A blitter is a circuit, sometimes as a coprocessor or a logic block on a microprocessor , dedicated to the rapid movement and modification of data within a computer's memory . A blitter can copy large quantities of data from one memory area to another relatively quickly, and in parallel with the CPU , while freeing up the CPU's more complex capabilities for other operations. A typical use for a blitter is the movement of a bitmap , such as windows and icons in a graphical user interface or images and backgrounds in a 2D video game. The name comes from the bit blit operation of the 1973 Xerox Alto , which stands for bit-block transfer. A blit operation is more than a memory copy, because it can involve data that's not byte aligned (hence the bit in bit blit ), handling transparent pixels (pixels which should not overwrite the destination), and various ways of combining the source and destination data.

130-491: Blitters have largely been superseded by programmable graphics processing units . In computers without hardware accelerated raster graphics , which includes most 1970s and 1980s home computers and IBM PC compatibles through the mid-1990s, the frame buffer is commonly stored in CPU-accessible memory. Drawing is accomplished by updating the frame buffer via software. For fundamental graphics routines, like compositing

260-480: A GEMDOS file system which became part of Atari TOS (for "The Operating System", colloquially known as the "Tramiel Operating System"). This gave the ST a fast, hierarchical file system , essential for hard drives , and provided programmers with function calls similar to MS-DOS . The Atari ST character set is based on codepage 437 . After six months of intensive effort following Tramiel's takeover, Atari announced

390-491: A personal computer graphics display processor as a single large-scale integration (LSI) integrated circuit chip. This enabled the design of low-cost, high-performance video graphics cards such as those from Number Nine Visual Technology . It became the best-known GPU until the mid-1980s. It was the first fully integrated VLSI (very large-scale integration) metal–oxide–semiconductor ( NMOS ) graphics display processor for PCs, supported up to 1024×1024 resolution , and laid

520-562: A vector processor ), running compute kernels . This turns the massive computational power of a modern graphics accelerator's shader pipeline into general-purpose computing power. In certain applications requiring massive vector operations, this can yield several orders of magnitude higher performance than a conventional CPU. The two largest discrete (see " Dedicated graphics processing unit " above) GPU designers, AMD and Nvidia , are pursuing this approach with an array of applications. Both Nvidia and AMD teamed with Stanford University to create

650-470: A 16-bit bus, which reduces performance and cost. In another cost-reduction measure, Atari shipped the Falcon in an inexpensive case much like that of the ST and ST . Aftermarket upgrade kits allow it to be put in a desktop or rack-mount case, with the keyboard separate. Released in 1992, the Falcon was discontinued by Atari the following year. In Europe, C-Lab licensed the Falcon design from Atari and released

780-583: A GPU-based client for the Folding@home distributed computing project for protein folding calculations. In certain circumstances, the GPU calculates forty times faster than the CPUs traditionally used by such applications. GPGPUs can be used for many types of embarrassingly parallel tasks including ray tracing . They are generally suited to high-throughput computations that exhibit data-parallelism to exploit

910-507: A Vérité V2200 core to create a graphics card with a full T&L engine years before Nvidia's GeForce 256 ; This card, designed to reduce the load placed upon the system's CPU, never made it to market. NVIDIA RIVA 128 was one of the first consumer-facing GPU integrated 3D processing unit and 2D processing unit on a chip. OpenGL was introduced in the early '90s by SGI as a professional graphics API, with proprietary hardware support for 3D rasterization. In 1994 Microsoft acquired Softimage ,

1040-469: A concern—except to invoke the pixel shader). Nvidia's CUDA platform, first introduced in 2007, was the earliest widely adopted programming model for GPU computing. OpenCL is an open standard defined by the Khronos Group that allows for the development of code for both GPUs and CPUs with an emphasis on portability. OpenCL solutions are supported by Intel, AMD, Nvidia, and ARM, and according to

1170-560: A development machine for Capcom 's CP System arcade board. Fujitsu's FM Towns computer, released in 1989, had support for a 16,777,216 color palette. In 1988, the first dedicated polygonal 3D graphics boards were introduced in arcades with the Namco System 21 and Taito Air System. IBM introduced its proprietary Video Graphics Array (VGA) display standard in 1987, with a maximum resolution of 640×480 pixels. In November 1988, NEC Home Electronics announced its creation of

1300-404: A few months later and were included in new machines and as an upgrade for older machines. Atari originally intended to include GEM's GDOS (Graphical Device Operating System), which allows programs to send GEM VDI ( Virtual Device Interface ) commands to drivers loaded by GDOS. This allows developers to send VDI instructions to other devices simply by pointing to it. However, GDOS was not ready at

1430-657: A highly customizable function block and did not really "run" a program. Many of these disparities between vertex and pixel shading were not addressed until the Unified Shader Model . In October 2002, with the introduction of the ATI Radeon 9700 (also known as R300), the world's first Direct3D 9.0 accelerator, pixel and vertex shaders could implement looping and lengthy floating point math, and were quickly becoming as flexible as CPUs, yet orders of magnitude faster for image-array operations. Pixel shading

1560-555: A letter by Gilman Louie , head of Spectrum HoloByte . He stated that he had been warned by competitors that releasing a game like Falcon on the ST would fail because BBSs would widely disseminate it. Within 30 days of releasing the non- copy protected ST version, the game was available on BBSs with maps and code wheels . Because the ST market was smaller than that for the IBM PC, it was more vulnerable to piracy which, Louie said, seemed to be better organized and more widely accepted for

1690-723: A list price of US$ 999 (equivalent to about $ 2,800 in 2023) in the US, BYTE hailed it as the first computer to break the $ 1000 per megabyte price barrier. Compute! noted that the 1040ST is the first computer with one megabyte of RAM to sell for less than $ 2,500. A limited number of 1040STFs shipped with a single-sided floppy drive. Initial sales were strong, especially in Europe, where Atari sold 75% of its computers. West Germany became Atari's strongest market, with small business owners using them for desktop publishing and CAD. To address this growing market segment, Atari introduced

1820-449: A little under one year. Atari had intended to release the 130ST with 128 KB of RAM and the 260ST with 256 KB. However, the ST initially shipped without TOS in ROM and required booting TOS from floppy, taking 206 KB RAM away from applications. The 260ST was launched in Europe on a limited basis. Early models have six ROM sockets for easy upgrades to TOS. New ROMs were released

1950-470: A low-cost desktop publishing package. A custom blitter coprocessor improved some graphics performance, but was not included in all models. Developers wanting to use it had to detect its presence in their programs. Properly written applications using the GEM API automatically make use of the blitter. In late 1989, Atari Corporation released the 520ST and 1040ST (also written STE), enhanced version of

2080-587: A new design with an integrated hard-drive enclosure. The final model of ST computer is the Falcon030. Like the TT, it is 68030-based, at 16 MHz, but with improved video modes and an on-board Motorola 56001 audio digital signal processor . Like the Atari STE , it supports sampling frequencies above 44.1 kHz; the sampling master clock is 98340 Hz (which can be divided by a number between 2 and 16 to get

2210-552: A number of arcade games starting in 1988 with Narc and including Hard Drivin' , Smash TV , Mortal Kombat , and NBA Jam , It was also used in graphics accelerator boards in the 1990s. 1987: The IBM 8514/A display adapter, introduced with the IBM Personal System/2 computers in April 1987, includes bit block transfer hardware. 1987: The Atari Mega ST 2 ships with a blitter chip. Officially called

2340-466: A number of brand names. In 2009, Intel , Nvidia , and AMD / ATI were the market share leaders, with 49.4%, 27.8%, and 20.6% market share respectively. In addition, Matrox produces GPUs. Modern smartphones use mostly Adreno GPUs from Qualcomm , PowerVR GPUs from Imagination Technologies , and Mali GPUs from ARM . Modern GPUs have traditionally used most of their transistors to do calculations related to 3D computer graphics . In addition to

2470-633: A permanent bitmap makes them unsuitable for general desktop GUI acceleration. Graphics processing unit A graphics processing unit ( GPU ) is a specialized electronic circuit initially designed for digital image processing and to accelerate computer graphics , being present either as a discrete video card or embedded on motherboards , mobile phones , personal computers , workstations , and game consoles . After their initial design, GPUs were found to be useful for non-graphic calculations involving embarrassingly parallel problems due to their parallel structure . Other non-graphical uses include

2600-605: A pixel, but contain 8 single-bit pixels, 4 two-bit pixels, or a pair of 4-bit pixels. Manipulating packed pixels requires extra shifting and masking operations on the CPU. Blitters were developed to offload repetitive tasks of copying data or filling blocks of memory faster than possible by the CPU. This can be done in parallel with the CPU and also handle special cases which would be significantly slower if coded by hand, such as skipping over pixels marked as transparent or handling data that isn't byte-aligned. 1973: The Xerox Alto , where

2730-615: A report in 2011 by Evans Data, OpenCL had become the second most popular HPC tool. In 2010, Nvidia partnered with Audi to power their cars' dashboards, using the Tegra GPU to provide increased functionality to cars' navigation and entertainment systems. Advances in GPU technology in cars helped advance self-driving technology . AMD's Radeon HD 6000 series cards were released in 2010, and in 2011 AMD released its 6000M Series discrete GPUs for mobile devices. The Kepler line of graphics cards by Nvidia were released in 2012 and were used in

2860-717: A second 1 bit per pixel image used as a mask to indicate which pixels to transfer and which to leave untouched. The mask operates like a stencil . The logical operation is: Hardware sprites are small bitmaps which can be positioned independently and are composited together with the background on-the-fly by the video chip. The frame buffer is not modified. The downside of sprites is a limit of moving graphics per scanline, which can range from three ( Atari 2600 ) to eight ( Commodore 64 and Atari 8-bit computers ) to significantly higher for 16-bit consoles and arcade hardware (the Neo Geo can display 96 sprites per line. The inability to update

2990-721: A single double-sided one, to avoid alienating early adopters . Some software uses formats which allow the full disk to be read by double-sided drives but still lets single-sided drives access side A of the disk. Many magazine coverdisks (such as the first 30 issues of ST Format ) were designed this way, as were a few games. The music in Carrier Command and the intro sequence in Populous are not accessible to single-sided drives, for example. STs with double-sided drives can read disks formatted by MS-DOS , but IBM PC compatibles can not read Atari disks because of differences in

3120-411: A single physical pool of RAM, allowing more efficient transfer of data. Hybrid GPUs compete with integrated graphics in the low-end desktop and notebook markets. The most common implementations of this are ATI's HyperMemory and Nvidia's TurboCache . Hybrid graphics cards are somewhat more expensive than integrated graphics, but much less expensive than dedicated graphics cards. They share memory with

3250-683: A single resolution of 640 × 400 at 71.25 Hz. The attached monitor determines available resolutions, so each application either supports both types of monitors or only one. Most ST games require colour with productivity software favouring the monochrome. The Philips CM8833-II was a popular color monitor for the Atari ST. Atari initially used single-sided 3.5 inch floppy disk drives that could store up to 360 KB. Later drives were double-sided and stored 720 KB. Some commercial software, particularly games, shipped by default on single-sided disks, even supplying two 360 KB floppies instead of

3380-404: A smaller image into a larger one (such as for a video game) or drawing a filled rectangle, large amounts of memory need to be manipulated, and many cycles are spent fetching and decoding short loops of load/store instructions. For CPUs without caches, the bus requirement for instructions is as significant as data. To reduce the size of the frame buffer, a single byte may not necessarily correspond to

3510-522: A specific use, real-time 3D graphics, or other mass calculations: Dedicated graphics processing units uses RAM that is dedicated to the GPU rather than relying on the computer’s main system memory. This RAM is usually specially selected for the expected serial workload of the graphics card (see GDDR ). Sometimes systems with dedicated discrete GPUs were called "DIS" systems as opposed to "UMA" systems (see next section). Dedicated GPUs are not necessarily removable, nor does it necessarily interface with

3640-603: A variety of imitators: by 1995, all major PC graphics chip makers had added 2D acceleration support to their chips. Fixed-function Windows accelerators surpassed expensive general-purpose graphics coprocessors in Windows performance, and such coprocessors faded from the PC market. Throughout the 1990s, 2D GUI acceleration evolved. As manufacturing capabilities improved, so did the level of integration of graphics chips. Additional application programming interfaces (APIs) arrived for

3770-538: A variety of tasks, such as Microsoft's WinG graphics library for Windows 3.x , and their later DirectDraw interface for hardware acceleration of 2D games in Windows 95 and later. In the early- and mid-1990s, real-time 3D graphics became increasingly common in arcade, computer, and console games, which led to increasing public demand for hardware-accelerated 3D graphics. Early examples of mass-market 3D graphics hardware can be found in arcade system boards such as

3900-493: A version of Digital Research 's GEM interface / operating system from February 1985. The Atari 1040ST , released in 1986 with 1 MB of memory, was the first home computer with a cost per kilobyte of RAM under US$ 1/KB. After Jack Tramiel purchased the assets of the Atari, Inc. consumer division in 1984 to create Atari Corporation, the 520ST was designed in five months by a small team led by Shiraz Shivji . Alongside

4030-453: Is a general purpose 32-bit processor with built-in instructions, including PIXBLT (Pixel Block Transfer), for manipulating bitmap data. It is optimized for cases that would take extra processing if implemented in software, such as handling transparent pixels, working with non-byte aligned data, and converting between bit depths. PIXBLT provides 22 ways of combining the source and destination data. The TMS34010 serves as both CPU and GPU for

4160-453: Is based on CP/M-68K, a direct port of CP/M to the 68000. By 1985, CP/M was becoming increasingly outdated; it did not support subdirectories, for example. Digital Research was also in the process of building GEMDOS, a disk operating system for GEM, and debated whether a port of it could be completed in time for product delivery in June. The decision was eventually taken to port it, resulting in

4290-712: Is commonly referred to as "GPU accelerated video decoding", "GPU assisted video decoding", "GPU hardware accelerated video decoding", or "GPU hardware assisted video decoding". Recent graphics cards decode high-definition video on the card, offloading the central processing unit. The most common APIs for GPU accelerated video decoding are DxVA for Microsoft Windows operating systems and VDPAU , VAAPI , XvMC , and XvBA for Linux-based and UNIX-like operating systems. All except XvMC are capable of decoding videos encoded with MPEG-1 , MPEG-2 , MPEG-4 ASP (MPEG-4 Part 2) , MPEG-4 AVC (H.264 / DivX 6), VC-1 , WMV3 / WMV9 , Xvid / OpenDivX (DivX 4), and DivX 5 codecs , while XvMC

4420-736: Is not available. Technologies such as Scan-Line Interleave by 3dfx, SLI and NVLink by Nvidia and CrossFire by AMD allow multiple GPUs to draw images simultaneously for a single screen, increasing the processing power available for graphics. These technologies, however, are increasingly uncommon; most games do not fully use multiple GPUs, as most users cannot afford them. Multiple GPUs are still used on supercomputers (like in Summit ), on workstations to accelerate video (processing multiple videos at once) and 3D rendering, for VFX , GPGPU workloads and for simulations, and in AI to expedite training, as

4550-708: Is often used for bump mapping , which adds texture to make an object look shiny, dull, rough, or even round or extruded. With the introduction of the Nvidia GeForce 8 series and new generic stream processing units, GPUs became more generalized computing devices. Parallel GPUs are making computational inroads against the CPU, and a subfield of research, dubbed GPU computing or GPGPU for general purpose computing on GPU , has found applications in fields as diverse as machine learning , oil exploration , scientific image processing , linear algebra , statistics , 3D reconstruction , and stock options pricing. GPGPU

4680-518: Is only capable of decoding MPEG-1 and MPEG-2. There are several dedicated hardware video decoding and encoding solutions . Video decoding processes that can be accelerated by modern GPU hardware are: These operations also have applications in video editing, encoding, and transcoding. An earlier GPU may support one or more 2D graphics API for 2D acceleration, such as GDI and DirectDraw . A GPU can support one or more 3D graphics API, such as DirectX , Metal , OpenGL , OpenGL ES , Vulkan . In

4810-687: Is the Super FX chip, a RISC -based on-cartridge graphics chip used in some SNES games, notably Doom and Star Fox . Some systems used DSPs to accelerate transformations. Fujitsu , which worked on the Sega Model 2 arcade system, began working on integrating T&L into a single LSI solution for use in home computers in 1995; the Fujitsu Pinolite, the first 3D geometry processor for personal computers, released in 1997. The first hardware T&L GPU on home video game consoles

4940-457: Is the case with Nvidia's lineup of DGX workstations and servers, Tesla GPUs, and Intel's Ponte Vecchio GPUs. Integrated graphics processing units (IGPU), integrated graphics , shared graphics solutions , integrated graphics processors (IGP), or unified memory architectures (UMA) use a portion of a computer's system RAM rather than dedicated graphics memory. IGPs can be integrated onto a motherboard as part of its northbridge chipset, or on

5070-467: Is the first Atari with PCM audio; using a new chip, it added the ability to play back 8-bit (signed) samples at 6258 Hz, 12,517 Hz, 25,033 Hz, and even 50,066 Hz, via direct memory access (DMA). The channels are arranged as either a mono track or a track of LRLRLRLR... bytes. RAM is now much more simply upgradable via SIMMs . Two enhanced joystick ports were added (two normal joysticks can be plugged into each port with an adapter), with

5200-609: The GeForce 256 as "the world's first GPU". It was presented as a "single-chip processor with integrated transform, lighting, triangle setup/clipping , and rendering engines". Rival ATI Technologies coined the term " visual processing unit " or VPU with the release of the Radeon 9700 in 2002. The AMD Alveo MA35D features dual VPU’s, each using the 5 nm process in 2023. In personal computers, there are two main forms of GPUs. Each has many synonyms: Most GPUs are designed for

5330-517: The Intel Core line and with contemporary Pentiums and Celerons. This resulted in a large nominal market share, as the majority of computers with an Intel CPU also featured this embedded graphics processor. These generally lagged behind discrete processors in performance. Intel re-entered the discrete GPU market in 2022 with its Arc series, which competed with the then-current GeForce 30 series and Radeon 6000 series cards at competitive prices. In

5460-516: The Jaguar video game console. The Atari ST was born from the rivalry between home computer makers Atari, Inc. and Commodore International . Jay Miner , one of the designers of the custom chips in the Atari 2600 and Atari 8-bit computers , tried to convince Atari management to create a new chipset for a video game console and computer. When his idea was rejected, he left Atari to form a small think tank called Hi-Toro in 1982 and began designing

5590-605: The Macintosh , Amiga , Apple IIGS and Acorn Archimedes , the ST is part of a mid-1980s generation of computers with 16- or 32-bit processors, 256  KB or more of RAM, and mouse -controlled graphical user interfaces. "ST" officially stands for "Sixteen/Thirty-two", referring to the Motorola 68000 's 16-bit external bus and 32-bit internals. The ST was sold with either Atari's color monitor or less expensive monochrome monitor . Color graphics modes are available only on

5720-586: The Mega STE , is an STE in a grey Atari TT case that had a switchable 16 MHz, dual-bus design (16-bit external, 32-bit internal), optional Motorola 68881 FPU , built-in 1.44 MB "HD" 3 1 ⁄ 2 -inch floppy disk drive, VME expansion slot, a network port (very similar to that used by Apple's LocalTalk ) and an optional built-in 3 1 ⁄ 2 " hard drive. It also shipped with TOS 2.00 (better support for hard drives, enhanced desktop interface, memory test, 1.44 MB floppy support, bug fixes). It

5850-583: The Motorola 68000 . The Atari ST design was completed in five months in 1984, concluding with it being shown at the January 1985 Consumer Electronics Show. A custom sound processor called AMY had been in development at Atari, Inc. and was considered for the new ST computer design. The chip needed more time to complete, so AMY was dropped in favor of a commodity Yamaha YM2149F variant of the General Instrument AY-3-8910 . Soon after

5980-465: The PowerVR and the 3dfx Voodoo . However, as manufacturing technology continued to progress, video, 2D GUI acceleration, and 3D functionality were all integrated into one chip. Rendition 's Verite chipsets were among the first to do this well. In 1997, Rendition collaborated with Hercules and Fujitsu on a "Thriller Conspiracy" project which combined a Fujitsu FXG-1 Pinolite geometry processor with

6110-522: The Sega Model 1 , Namco System 22 , and Sega Model 2 , and the fifth-generation video game consoles such as the Saturn , PlayStation , and Nintendo 64 . Arcade systems such as the Sega Model 2 and SGI Onyx -based Namco Magic Edge Hornet Simulator in 1993 were capable of hardware T&L ( transform, clipping, and lighting ) years before appearing in consumer graphics cards. Another early example

6240-616: The Video Electronics Standards Association (VESA) to develop and promote a Super VGA (SVGA) computer display standard as a successor to VGA. Super VGA enabled graphics display resolutions up to 800×600 pixels , a 36% increase. In 1991, S3 Graphics introduced the S3 86C911 , which its designers named after the Porsche 911 as an indication of the performance increase it promised. The 86C911 spawned

6370-412: The motherboard by means of an expansion slot such as PCI Express (PCIe) or Accelerated Graphics Port (AGP). They can usually be replaced or upgraded with relative ease, assuming the motherboard is capable of supporting the upgrade. A few graphics cards still use Peripheral Component Interconnect (PCI) slots, but their bandwidth is so limited that they are generally used only when a PCIe or AGP slot

6500-465: The rotation and translation of vertices into different coordinate systems . Recent developments in GPUs include support for programmable shaders which can manipulate vertices and textures with many of the same operations that are supported by CPUs , oversampling and interpolation techniques to reduce aliasing , and very high-precision color spaces . Several factors of GPU construction affect

6630-510: The "Atari ST Bit-Block Transfer Processor", stylized as BLiTTER, it provides 16 options for merging source and destination data. The blitter is supported on most subsequent ST machines. 1989: The short-lived Atari Transputer Workstation contains blitter hardware as part of its (Mega ST-based) "Blossom" video system. 1989: The Atari Lynx color handheld game system has a custom blitter with scaling and distortion effects. 1993: The Atari Jaguar game console has blitter hardware as part of

6760-534: The 1850XLD. After leaving Commodore International in January 1984, Jack Tramiel formed Tramel (without an "i") Technology, Ltd. with his sons and other ex-Commodore employees and, in April, began planning a new computer. Interested in Atari's overseas manufacturing and worldwide distribution network, Tramiel negotiated with Warner in May and June 1984. He secured funding and bought Atari's consumer division, which included

6890-483: The 1970s, the term "GPU" originally stood for graphics processor unit and described a programmable processing unit working independently from the CPU that was responsible for graphics manipulation and output. In 1994, Sony used the term (now standing for graphics processing unit ) in reference to the PlayStation console's Toshiba -designed Sony GPU . The term was popularized by Nvidia in 1999, who marketed

7020-598: The 2020s, GPUs have been increasingly used for calculations involving embarrassingly parallel problems, such as training of neural networks on enormous datasets that are needed for large language models . Specialized processing cores on some modern workstation's GPUs are dedicated for deep learning since they have significant FLOPS performance increases, using 4×4 matrix multiplication and division, resulting in hardware performance up to 128 TFLOPS in some applications. These tensor cores are expected to appear in consumer cards, as well. Many companies have produced GPUs under

7150-422: The 3D hardware, today's GPUs include basic 2D acceleration and framebuffer capabilities (usually with a VGA compatibility mode). Newer cards such as AMD/ATI HD5000–HD7000 lack dedicated 2D acceleration; it is emulated by 3D hardware. GPUs were initially used to accelerate the memory-intensive work of texture mapping and rendering polygons. Later, units were added to accelerate geometric calculations such as

7280-565: The 520ST at the Winter Consumer Electronics Show in Las Vegas in January 1985. InfoWorld assessed the prototypes shown at computer shows as follows: Pilot production models of the Atari machine are much slicker than the hand-built models shown at earlier computer fairs; it doesn't look like a typical Commodore 64-style, corner-cutting, low-cost Jack Tramiel product of the past. Atari unexpectedly displayed

7410-505: The Amiga had almost none. After Atlanta COMDEX, The New York Times reported that "more than 100 software titles will be available for the [ST], most written by small software houses that desperately need work", and contrasted the "small, little-known companies" at Las Vegas with the larger ones like Electronic Arts and Activision , which planned Amiga applications. Trip Hawkins of Electronic Arts said, "I don't think Atari understands

7540-536: The Atari 520ST in June 1985. In March 1987, the two companies settled the dispute out of court in a closed decision. The lead architect of the new computer project at Tramel Technology and Atari Corporation was ex-Commodore employee Shiraz Shivji , who previously worked on the Commodore 64 's development. Different CPUs were investigated, including the 32-bit National Semiconductor NS32000 , but engineers were disappointed with its performance, and they moved to

7670-403: The Atari buyout, Microsoft suggested to Tramiel that it could port Windows to the platform, but the delivery date was out by two years. Another possibility was Digital Research , which was working on a new GUI-based system then known as Crystal, soon to become GEM . Another option was to write a new operating system, but this was rejected as Atari management was unsure whether the company had

7800-574: The C-Lab Falcon Mk I, identical to Atari's Falcon except for slight modifications to the audio circuitry. The Mk II added an internal 500 MB SCSI hard disk; and the Mk X further added a desktop case. C-Lab Falcons were also imported to the US by some Atari dealers. As with the Atari 8-bit computers , software publishers attributed their reluctance to produce Atari ST products in part to—as Compute! reported in 1988—the belief in

7930-698: The CPU for relatively slow system RAM, as it has minimal or no dedicated video memory. IGPs use system memory with bandwidth up to a current maximum of 128 GB/s, whereas a discrete graphics card may have a bandwidth of more than 1000 GB/s between its VRAM and GPU core. This memory bus bandwidth can limit the performance of the GPU, though multi-channel memory can mitigate this deficiency. Older integrated graphics chipsets lacked hardware transform and lighting , but newer ones include it. On systems with "Unified Memory Architecture" (UMA), including modern AMD processors with integrated graphics, modern Intel processors with integrated graphics, Apple processors,

The ST supports a monochrome or colour monitor. The colour hardware supports two resolutions: 320 × 200 pixels, with 16 of 512 colours; and 640 × 200, with 4 of 512 colours. The monochrome monitor was less expensive and has

A feature in this GPU microarchitecture included GPU boost, a technology that adjusts the clock-speed of a video card to increase or decrease it according to its power draw. The Kepler microarchitecture was manufactured on the 28 nm process . The PS4 and Xbox One were released in 2013; they both use GPUs based on AMD's Radeon HD 7850 and 7790 . Nvidia's Kepler line of GPUs

These chips were essentially previous-generation 2D accelerators with 3D features bolted on. Many were pin-compatible with the earlier-generation chips for ease of implementation and minimal cost. Initially, 3D graphics were possible only with discrete boards dedicated to accelerating 3D functions (and lacking 2D graphical user interface (GUI) acceleration entirely) such as

8450-573: The PS5 and Xbox Series (among others), the CPU cores and the GPU block share the same pool of RAM and memory address space. This allows the system to dynamically allocate memory between the CPU cores and the GPU block based on memory needs (without needing a large static split of the RAM) and thanks to zero copy transfers, removes the need for either copying data over a bus (computing) between physically separate RAM pools or copying between separate address spaces on

8580-556: The R9 290X or better at the time of their release. Cards based on the Pascal microarchitecture were released in 2016. The GeForce 10 series of cards are of this generation of graphics cards. They are made using the 16 nm manufacturing process which improves upon previous microarchitectures. Nvidia released one non-consumer card under the new Volta architecture, the Titan V. Changes from

8710-535: The RTX 20 series GPUs that added ray-tracing cores to GPUs, improving their performance on lighting effects. Polaris 11 and Polaris 10 GPUs from AMD are fabricated by a 14 nm process. Their release resulted in a substantial increase in the performance per watt of AMD video cards. AMD also released the Vega GPU series for the high end market as a competitor to Nvidia's high end Pascal cards, also featuring HBM2 like

8840-560: The RX 6800, RX 6800 XT, and RX 6900 XT. The RX 6700 XT, which is based on Navi 22, was launched in early 2021. The PlayStation 5 and Xbox Series X and Series S were released in 2020; they both use GPUs based on the RDNA 2 microarchitecture with incremental improvements and different GPU configurations in each system's implementation. Intel first entered the GPU market in the late 1990s, but produced lackluster 3D accelerators compared to

8970-677: The ST at Atlanta COMDEX in May. Similarities to the original Macintosh and Tramiel's role in its development resulted in it being nicknamed Jackintosh . Atari's rapid development of the ST amazed many, but others were skeptical, citing its "cheap" appearance, Atari's uncertain financial health, and poor relations between Tramiel-led Commodore and software developers. Atari ST print advertisements stated, "America, We Built It For You", and quoted Atari president Sam Tramiel: "We promised. We delivered. With pride, determination, and good old ATARI know how". But Jack Tramiel admitted that sales of its earlier 8-bit systems were "very, very slow", Atari

9100-522: The ST or Amiga, and the majority of software companies were hesitant to support another platform beyond the IBM PC , Apple, and Commodore 64 . Philippe Kahn of Borland said, "These days, if I were a consumer, I'd stick with companies [such as Apple and IBM] I know will be around ". At Las Vegas COMDEX in November 1985, the industry was surprised by more than 30 companies exhibiting ST software while

9230-473: The ST or the Amiga. John C. Dvorak wrote that the public saw both Commodore and Atari as selling "cheap disposable" game machines, in part because of their computers' sophisticated graphics. The original 520ST case design was created by Ira Velinsky, Atari's chief Industrial Designer. It is wedge-shaped, with bold angular lines and a series of grilles cut into the rear for airflow. The keyboard has soft tactile feedback and rhomboid-shaped function keys across

9360-528: The ST with improvements to the multimedia hardware and operating system. It features an increased color palette of 4,096 colors from the ST's 512 (though the maximum displayable palette without programming tricks is still limited to 16 in the lowest 320 × 200 resolution, and even fewer in higher resolutions), genlock support, and a blitter coprocessor (stylized as "BLiTTER") which can quickly move large blocks of data (particularly, graphics data) around in RAM. The STE

9490-547: The ST. After a meeting with Atari, one analyst said, "We've seen marketing strategies changed before our eyes". Tramiel's poor reputation influenced potential software developers. One said, "Dealing with Commodore is like dealing with Attila the Hun. I don't know if Tramiel will be following his old habits ... I don't see a lot of people rushing to get software on the machine." Large business-software companies like Lotus , Ashton-Tate , and Microsoft did not promise software for either

9620-516: The ST1 at Comdex in 1986. Renamed to Mega, it includes a high-quality detached keyboard, a stronger case to support the weight of a monitor, and an internal bus expansion connector. An optional 20 MB hard drive can be placed below or above the main case. Initially equipped with 2 or 4 MB of RAM (a 1 MB version, the Mega 1, followed), the Mega machines can be combined with Atari's laser printer for

9750-587: The SubGenius ). The ST was less expensive than most contemporaries, including the Macintosh Plus , and is faster than many. Largely as a result of its price and performance factor, the ST became fairly popular, especially in Europe where foreign-exchange rates amplified prices. The company's English advertising slogan of the era was "Power Without the Price". An Atari ST and terminal emulation software

9880-608: The Titan V. In 2019, AMD released the successor to their Graphics Core Next (GCN) microarchitecture/instruction set. Dubbed RDNA, the first product featuring it was the Radeon RX 5000 series of video cards. The company announced that the successor to the RDNA microarchitecture would be incremental (aka a refresh). AMD unveiled the Radeon RX 6000 series , its RDNA 2 graphics cards with support for hardware-accelerated ray tracing. The product series, launched in late 2020, consisted of

10010-493: The Titan XP, Pascal's high-end card, include an increase in the number of CUDA cores, the addition of tensor cores, and HBM2 . Tensor cores are designed for deep learning, while high-bandwidth memory is on-die, stacked, lower-clocked memory that offers an extremely wide memory bus. To emphasize that the Titan V is not a gaming card, Nvidia removed the "GeForce GTX" suffix it adds to consumer gaming cards. In 2018, Nvidia launched

10140-456: The actual display rate. Most GPUs made since 1995 support the YUV color space and hardware overlays , important for digital video playback, and many GPUs made since 2000 also support MPEG primitives such as motion compensation and iDCT . This hardware-accelerated video decoding, in which portions of the video decoding process and video post-processing are offloaded to the GPU hardware,

10270-462: The actual sampling frequencies). It can play the STE sample frequencies (up to 50066 Hz) in 8 or 16 bit, mono or stereo, all by using the same DMA interface as the STE, with a few additions. It can both play back and record samples, with 8 mono channels and 4 stereo channels, allowing musicians to use it for recording to hard drive. Although the 68030 microprocessor can use 32-bit memory, the Falcon uses

10400-609: The basis of the Texas Instruments Graphics Architecture ("TIGA") Windows accelerator cards. In 1987, the IBM 8514 graphics system was released. It was one of the first video cards for IBM PC compatibles to implement fixed-function 2D primitives in electronic hardware . Sharp 's X68000 , released in 1987, used a custom graphics chipset with a 65,536 color palette and hardware support for sprites, scrolling, and multiple playfields. It served as

10530-406: The blitter to begin operating. The CPU is free for other processing while the blitter is working, though the blit running in parallel uses memory bandwidth. To copy data with fully transparent pixels—such as sprites—some hardware allows a specific pixel value to be ignored, such as color 0, during the blit. Those pixels are not written to the destination. Another approach on some systems is to have

10660-612: The books: " Game of X " v.1 and v.2 by Russel Demaria, " Renegades of the Empire " by Mike Drummond, " Opening the Xbox " by Dean Takahashi and " Masters of Doom " by David Kushner. The Nvidia GeForce 256 (also known as NV10) was the first consumer-level card with hardware-accelerated T&L; While the OpenGL API provided software support for texture mapping and lighting the first 3D hardware acceleration for these features arrived with

10790-676: The chipset. Tramiel countered by suing Amiga Corp. on August 13, 1984, seeking damages and an injunction to bar Amiga (and effectively Commodore) from producing anything with its technology. The lawsuit left the Amiga team in limbo during mid-1984. Commodore eventually moved forward, with plans to improve the chipset and develop an operating system . Commodore announced the Amiga 1000 with the Lorraine chipset in July 1985, but it wasn't available in quantity until 1986. The delay gave Atari time to deliver

10920-579: The competition at the time. Rather than attempting to compete with the high-end manufacturers Nvidia and ATI/AMD, they began integrating Intel Graphics Technology GPUs into motherboard chipsets, beginning with the Intel 810 for the Pentium III, and later into CPUs. They began with the Intel Atom 'Pineview' laptop processor in 2009, continuing in 2010 with desktop processors in the first generation of

11050-530: The console and home computer departments, in July. As executives and engineers left Commodore to join Tramel Technology, Commodore responded by filing lawsuits against four former engineers for infringement of trade secrets . The Tramiels did not purchase the employee contracts with the assets of Atari, Inc. and re-hired approximately 100 of the 900 former employees. Tramel Technology soon changed its name to Atari Corporation . Amid rumors that Tramiel

11180-405: The custom "Tom" chip. 1996: The VESA Group introduced a standardized way to access features like hardware Bit Block transfers with VBE/accelerator functions (VBE/AF) on IBM PC compatibles. Typically, a computer program puts information into certain hardware registers describing what memory transfer needs to be completed and the logical operations to perform on the data. The CPU then triggers

11310-541: The dominant CGI movie production tool used for early CGI movie hits like Jurassic Park, Terminator 2 and Titanic. With that deal came a strategic relationship with SGI and a commercial license of SGI's OpenGL libraries enabling Microsoft to port the API to the Windows NT OS but not to the upcoming release of Windows '95. Although it was little known at the time, SGI had contracted with Microsoft to transition from Unix to

11440-440: The existence of a "higher-than-normal amount of software piracy". That year, WordPerfect threatened to discontinue the Atari ST version of its word processor because the company discovered that pirate bulletin board systems (BBSs) were distributing it, causing ST-Log to warn that "we had better put a stop to piracy now ... it can have harmful effects on the longevity and health of your computer". In 1989, magazines published

11570-517: The first Direct3D accelerated consumer GPU's . Nvidia was first to produce a chip capable of programmable shading : the GeForce 3 . Each pixel could now be processed by a short program that could include additional image textures as inputs, and each geometric vertex could likewise be processed by a short program before it was projected onto the screen. Used in the Xbox console, this chip competed with

11700-479: The first Direct3D GPU's. Nvidia, quickly pivoted from a failed deal with Sega in 1996 to aggressively embracing support for Direct3D. In this era Microsoft merged their internal Direct3D and OpenGL teams and worked closely with SGI to unify driver standards for both industrial and consumer 3D graphics hardware accelerators. Microsoft ran annual events for 3D chip makers called "Meltdowns" to test their 3D hardware and drivers to work both with Direct3D and OpenGL. It

11830-430: The first major CMOS graphics processor for personal computers. The ARTC could display up to 4K resolution when in monochrome mode. It was used in a number of graphics cards and terminals during the late 1980s. In 1985, the Amiga was released with a custom graphics chip including a blitter for bitmap manipulation, line drawing, and area fill. It also included a coprocessor with its own simple instruction set, that

11960-547: The football for Charlie Brown , you can believe Jack Tramiel"; another said that because of its experience with Tramiel, "our interest in Atari is zero, zilch". Neither Atari nor Commodore could persuade large chains like ComputerLand or BusinessLand to sell its products. Observers criticized Atari's erratic discussion of its stated plans for the new computer, as it shifted between using mass merchandisers , specialty computer stores, and both. When asked at COMDEX, Atari executives could not name any computer stores that would carry

12090-463: The former while the highest-resolution mode requires the monochrome monitor. Some models can display the color modes on a TV. In Germany and some other markets, the ST gained a foothold for CAD and desktop publishing . With built-in MIDI ports, it was popular for music sequencing and as a controller of musical instruments among amateur and professional musicians. The Atari ST's primary competitor

12220-496: The forthcoming Windows '95 consumer OS, in '95 Microsoft announced the acquisition of UK based Rendermorphics Ltd and the Direct3D driver model for the acceleration of consumer 3D graphics. The Direct3D driver model shipped with DirectX 2.0 in 1996. It included standards and specifications for 3D chip makers to compete to support 3D texture, lighting and Z-buffering. ATI, which was later to be acquired by AMD, began development on

12350-441: The forthcoming Windows NT OS , the deal which was signed in 1995 was not announced publicly until 1998. In the intervening period, Microsoft worked closely with SGI to port OpenGL to Windows NT. In that era OpenGL had no standard driver model for competing hardware accelerators to compete on the basis of support for higher level 3D texturing and lighting functionality. In 1994 Microsoft announced DirectX 1.0 and support for gaming in

12480-483: The foundations for the emerging PC graphics market. It was used in a number of graphics cards and was licensed for clones such as the Intel 82720, the first of Intel's graphics processing units . The Williams Electronics arcade games Robotron 2084 , Joust , Sinistar , and Bubbles , all released in 1982, contain custom blitter chips for operating on 16-color bitmaps. In 1984, Hitachi released ARTC HD63484,

12610-435: The keyboard. An "FM" variant includes an RF modulator allowing a television to be used instead of a monitor. The trailing "F" and "FM" were often dropped in common usage. In BYTE magazine's March 1986 cover photo of the system, the name plate reads 1040ST but in the headline and article it's simply "1040ST". The 1040ST is one of the earliest personal computers shipped with a base RAM configuration of 1 MB. With

12740-405: The layout of data on track 0. Atari upgraded the basic design in 1986 with the 1040STF, stylized as 1040ST : essentially a 520ST with twice the RAM and with the power supply and a double-sided floppy drive built-in instead of external. This adds to the size of the machine, but reduces cable clutter. The joystick and mouse ports, formerly on the right side of the machine, are in a recess underneath

12870-581: The motherboard in a standard fashion. The term "dedicated" refers to the fact that graphics cards have RAM that is dedicated to the card's use, not to the fact that most dedicated GPUs are removable. Dedicated GPUs for portable computers are most commonly interfaced through a non-standard and often proprietary slot due to size and weight constraints. Such ports may still be considered PCIe or AGP in terms of their logical host interface, even if they are not physically interchangeable with their counterparts. Graphics cards with dedicated GPUs typically interface with

13000-402: The new "Lorraine" chipset. Hi-Toro, by then renamed Amiga, ran out of capital to complete Lorraine's development, and Atari, now owned by Warner Communications , paid Amiga to continue its work. In return, Atari received exclusive use of the Lorraine design for one year as a video game console. After that time, Atari had the right to add a keyboard and market the complete computer, designated

13130-485: The new connectors placed in more easily accessed locations on the side of the case. The enhanced joystick ports were re-used in the Atari Jaguar console and are compatible. The STE models initially had software and hardware conflicts resulting in some applications and video games written for the ST line being unstable or even completely unusable, primarily caused by programming direct hardware calls which bypassed

13260-410: The number of core on-silicon processor units within the GPU chip that perform the core calculations, typically working in parallel with other SM/CUs on the GPU. GPU performance is typically measured in floating point operations per second ( FLOPS ); GPUs in the 2010s and 2020s typically deliver performance measured in teraflops (TFLOPS). This is an estimated performance measure, as other factors can affect

13390-519: The one in the PlayStation 2 , which used a custom vector unit for hardware accelerated vertex processing (commonly referred to as VU0/VU1). The earliest incarnations of shader execution engines used in Xbox were not general purpose and could not execute arbitrary pixel code. Vertices and pixels were processed by different units which had their own resources, with pixel shaders having tighter constraints (because they execute at higher frequencies than vertices). Pixel shading engines were actually more akin to

13520-485: The operating system. Furthermore, even having a joystick plugged in would sometimes cause strange behavior with a few applications (such as the WYSIWYG word-processor application 1st Word Plus ). Sleepwalker was the only STE-only game from a major publisher, but there were STe enhancements in games such as Another World , Zool and The Chaos Engine , as well as exclusives from smaller companies. The last STE machine,

13650-410: The performance of the card for real-time rendering, such as the size of the connector pathways in the semiconductor device fabrication , the clock signal frequency, and the number and size of various on-chip memory caches . Performance is also affected by the number of streaming multiprocessors (SM) for NVidia GPUs, or compute units (CU) for AMD GPUs, or Xe cores for Intel discrete GPUs, which describe

13780-480: The required expertise. Digital Research was fully committed to the Intel platform, so a team from Atari was sent to the Digital Research headquarters to work with the "Monterey Team", which comprised a mixture of Atari and Digital Research engineers. Atari's Leonard Tramiel oversaw "Project Jason" (also known as The Operating System) for the ST series, named for designer and developer Jason Loveman. GEM

13910-482: The same die (integrated circuit) with the CPU (like AMD APU or Intel HD Graphics ). On certain motherboards, AMD's IGPs can use dedicated sideport memory: a separate fixed block of high performance memory that is dedicated for use by the GPU. As of early 2007 computers with integrated graphics account for about 90% of all PC shipments. They are less costly to implement than dedicated graphics processing, but tend to be less capable. Historically, integrated processing

14040-410: The same hardware in other games from the time period, including Sinistar and Joust . 1984: The MS-DOS compatible Mindset personal computer contains a custom VLSI chip to move rectangular sections of a bitmap. The hardware handles transparency and eight modes for combining the source and destination data. The Mindset was claimed to have graphics up to 50x faster than IBM PC compatibles of

14170-415: The scan lines map to specific bitmapped or character modes and where the memory is stored (so there did not need to be a contiguous frame buffer). 6502 machine code subroutines could be triggered on scan lines by setting a bit on a display list instruction. ANTIC also supported smooth vertical and horizontal scrolling independent of the CPU. The NEC μPD7220 was the first implementation of

14300-450: The screen. The design was licensed by Intel and sold as the 82720 graphics display controller. 1982: The Robotron: 2084 arcade video game from Williams Electronics includes two blitter chips which allow the game to have up to 80 simultaneously moving objects. Performance was measured at roughly 910 KB/second. The blitter operates on 4-bit (16 color) pixels where color 0 is transparent, allowing for non-rectangular shapes. Williams used

14430-623: The software business. I'm still skeptical about its resources and its credibility." Although Michael Berlyn of Infocom promised that his company would quickly publish all of its games for the new computer, he doubted many others would soon do so. Spinnaker and Lifetree were more positive, both promising to release ST software. Spinnaker said that "Atari has a vastly improved attitude toward software developers. They are eager to give us technical support and machines". Lifetree said, "We are giving Atari high priority". Some, such as Software Publishing Corporation , were unsure of whether to develop for

14560-486: The system and have a small dedicated memory cache, to make up for the high latency of the system RAM. Technologies within PCI Express make this possible. While these solutions are sometimes advertised as having as much as 768 MB of RAM, this refers to how much can be shared with the system memory. It is common to use a general purpose graphics processing unit (GPGPU) as a modified form of stream processor (or

14690-546: The term bit blit originated, has a bit block transfer instruction implemented in microcode , making it much faster than the same operation written on the CPU. The microcode was implemented by Dan Ingalls . 1978: The Bally Astrocade home console ships with primitive blitter hardware. 1982: In addition to drawing shape primitives, the NEC μPD7220 video display processor can transfer rectangular bitmaps to display memory via direct memory access and fill rectangular portions of

14820-511: The time the ST started shipping and was included in software packages and with later ST machines. Later versions of GDOS support vector fonts . A limited set of GEM fonts were included in the ROMs, including the ST's standard 8x8 pixel graphical character set. It contains four characters which can be placed together in a square, forming the face of J. R. "Bob" Dobbs (the figurehead of the Church of

14950-400: The time, but the system was not successful. 1985: One of the coprocessors in the Amiga personal computer is a blitter. The first US patent filing to use the term blitter was "Personal computer apparatus for block transfer of bit-mapped image data," assigned to Commodore-Amiga, Inc. The blitter performs an arbitrary boolean operation on three bit vectors of size 16: 1986: The TMS34010

15080-435: The top. It is an all-in-one unit, similar to earlier home computers like the Commodore 64 , but with a larger keyboard with cursor keys and a numeric keypad. The original has an external floppy drive (SF354) and AC adapter . Starting with the 1040ST, the floppy drive and power supply are integrated into the base unit. The ports on the 520ST remained largely unchanged over its history. Because of its bi-directional design,

15210-728: The training of neural networks and cryptocurrency mining . Arcade system boards have used specialized graphics circuits since the 1970s. In early video game hardware, RAM for frame buffers was expensive, so video chips composited data together as the display was being scanned out on the monitor. A specialized barrel shifter circuit helped the CPU animate the framebuffer graphics for various 1970s arcade video games from Midway and Taito , such as Gun Fight (1975), Sea Wolf (1976), and Space Invaders (1978). The Namco Galaxian arcade system in 1979 used specialized graphics hardware that supported RGB color , multi-colored sprites, and tilemap backgrounds. The Galaxian hardware

15340-462: The wide vector width SIMD architecture of the GPU. Atari ST Atari ST is a line of personal computers from Atari Corporation and the successor to the company's 8-bit home computers . The initial model, the Atari 520ST , had limited release in April–June 1985, and was widely available in July. It was the first personal computer with a bitmapped color graphical user interface , using

15470-471: Was capable of manipulating graphics hardware registers in sync with the video beam (e.g. for per-scanline palette switches, sprite multiplexing, and hardware windowing), or driving the blitter. In 1986, Texas Instruments released the TMS34010 , the first fully programmable graphics processor. It could run general-purpose code, but it had a graphics-oriented instruction set. During 1990–1992, this chip became

15600-504: Was considered unfit for 3D games or graphically intensive programs but could run less intensive programs such as Adobe Flash. Examples of such IGPs would be offerings from SiS and VIA circa 2004. However, modern integrated graphics processors such as AMD Accelerated Processing Unit and Intel Graphics Technology (HD, UHD, Iris, Iris Pro, Iris Plus, and Xe-LP ) can handle 2D graphics or low-stress 3D graphics. Since GPU computations are memory-intensive, integrated processing may compete with

15730-517: Was during this period of strong Microsoft influence over 3D standards that 3D accelerator cards moved beyond being simple rasterizers to become more powerful general purpose processors as support for hardware accelerated texture mapping, lighting, Z-buffering and compute created the modern GPU. During this period the same Microsoft team responsible for Direct3D and OpenGL driver standardization introduced their own Microsoft 3D chip design called Talisman . Details of this era are documented extensively in

15860-569: Was followed by the Maxwell line, manufactured on the same process. Nvidia's 28 nm chips were manufactured by TSMC in Taiwan using the 28 nm process. Compared to the 40 nm technology from the past, this manufacturing process allowed a 20 percent boost in performance while drawing less power. Virtual reality headsets have high system requirements; manufacturers recommended the GTX 970 and

15990-455: Was marketed as more affordable than a TT but more powerful than an ordinary ST. In 1990, Atari released the high-end workstation-oriented Atari TT030, based on a 32 MHz Motorola 68030 processor. The "TT" name ("Thirty-two/Thirty-two") continued the nomenclature because the 68030 chip has 32-bit buses both internally and externally. Originally planned with a 68020 CPU, the TT has improved graphics and more powerful support chips. The case has

16120-413: Was much cheaper than a Digital VT220 terminal, commonly needed by offices with central computers. By late 1985, the 520ST added an RF modulator for TV display. Computer Gaming World stated that Tramiel's poor pre-Atari reputation would likely make computer stores reluctant to deal with the company, hurting its distribution of the ST. One retailer said, "If you can believe Lucy when she holds

16250-401: Was negotiating to buy Atari, Amiga Corp. entered discussions with Commodore. This led to Commodore wanting to purchase Amiga Corporation outright, which Commodore believed would cancel any outstanding contracts, including Atari's. Instead of Amiga Corp. delivering Lorraine to Atari, Commodore delivered a check of $ 500,000 on Amiga's behalf, in effect returning the funds Atari invested in Amiga for

16380-401: Was out of cash, and employees feared that he would shut the company down. In early 1985, the 520ST shipped to the press, developers, and user groups , and in early July 1985 for general retail sales. It saved the company. By November, Atari stated that more than 50,000 520STs had been sold, "with U.S. sales alone well into five figures". The machine had gone from concept to store shelves in

16510-498: Was the Nintendo 64 's Reality Coprocessor , released in 1996. In 1997, Mitsubishi released the 3Dpro/2MP , a GPU capable of transformation and lighting, for workstations and Windows NT desktops; ATi used it for its FireGL 4000 graphics card , released in 1997. The term "GPU" was coined by Sony in reference to the 32-bit Sony GPU (designed by Toshiba ) in the PlayStation video game console, released in 1994. In

16640-402: Was the Amiga from Commodore . The 520ST and 1040ST were followed by the Mega series, the STE, and the portable STacy . In the early 1990s, Atari released three final evolutions of the ST with significant technical differences from the original models: TT030 (1990), Mega STE (1991), and Falcon (1992). Atari discontinued the entire ST computer line in 1993, shifting the company's focus to

16770-426: Was the precursor to what is now called a compute shader (e.g. CUDA, OpenCL, DirectCompute) and actually abused the hardware to a degree by treating the data passed to algorithms as texture maps and executing algorithms by drawing a triangle or quad with an appropriate pixel shader. This entails some overheads since units like the scan converter are involved where they are not needed (nor are triangle manipulations even

16900-484: Was widely used during the golden age of arcade video games , by game companies such as Namco , Centuri , Gremlin , Irem , Konami , Midway, Nichibutsu , Sega , and Taito. The Atari 2600 in 1977 used a video shifter called the Television Interface Adaptor . Atari 8-bit computers (1979) had ANTIC , a video processor which interpreted instructions describing a " display list "—the way
