The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company . The first system, EEC I, used processors and components developed by Toshiba in 1973. It began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
116-627: The EEC I and EEC II modules used a common processor and memory so they can be described together. The microprocessor was a 12-bit central processing unit manufactured by Toshiba , the TLCS-12 , which began development in 1971 and was completed in 1973. It was a 32 mm² chip with about 2,800 silicon gates , manufactured on a 6 μm process . The system's semiconductor memory included 512-bit RAM , 2 kb ROM and 2 kb EPROM . The system began production in 1974, and went into mass production in 1975. Ford's internal code name for
232-404: A MOS -based chipset as the core CPU. The design was significantly (approximately 20 times) smaller and much more reliable than the mechanical systems it competed against and was used in all of the early Tomcat models. This system contained "a 20-bit, pipelined , parallel multi-microprocessor ". The Navy refused to allow publication of the design until 1997. Released in 1998, the documentation on
348-505: A bit slice approach necessary. Instead of processing all of a long word on one integrated circuit, multiple circuits in parallel processed subsets of each word. While this required extra logic to handle, for example, carry and overflow within each slice, the result was a system that could handle, for example, 32-bit words using integrated circuits with a capacity for only four bits each. The ability to put large numbers of transistors on one chip makes it feasible to integrate memory on
464-460: A control logic section. The ALU performs addition, subtraction, and operations such as AND or OR. Each operation of the ALU sets one or more flags in a status register , which indicate the results of the last operation (zero value, negative number, overflow , or others). The control logic retrieves instruction codes from memory and initiates the sequence of operations required for the ALU to carry out
580-616: A static design , meaning that the clock frequency could be made arbitrarily low, or even stopped. This let the Galileo spacecraft use minimum electric power for long uneventful stretches of a voyage. Timers or sensors would awaken the processor in time for important tasks, such as navigation updates, attitude control, data acquisition, and radio communication. Current versions of the Western Design Center 65C02 and 65C816 also have static cores , and thus retain data even when
696-470: A 50-degree range depending on calibration. This increased spark capability requires greater separation of adjacent distributor cap electrodes to prevent cross-fire, resulting in a large-diameter distributor cap. EEC-III on carbureted cars controlled the same Ford 7200 VV carburetor as the EEC-II. On fuel-injected cars, the module fired two high pressure (approximately 40 psi) fuel injectors that were mounted in
812-529: A French defense firm. Motorola's biometric business unit was headquartered in Anaheim, California. The deal closed in April 2009. The unit became part of Sagem Morpho , which was renamed MorphoTrak . On March 26, 2008, Motorola's board of directors approved a split into two different publicly traded companies. This came after talk of selling the company to another corporation. These new companies would comprise
928-529: A ROM chip for storing the programs, a dynamic RAM chip for storing data, a simple I/O device, and a 4-bit central processing unit (CPU). Although not a chip designer, he felt the CPU could be integrated into a single chip, but as he lacked the technical know-how the idea remained just a wish for the time being. While the architecture and specifications of the MCS-4 came from the interaction of Hoff with Stanley Mazor ,
1044-708: A ban on the use of water that lasted three days and affected almost 5000 people in the area. Motorola was found to be the main source of the TCE, an industrial solvent that is thought to cause cancer. The TCE contamination was caused by a faulty blower on an air stripping tower that was used to take TCE from the water, and Motorola has attributed the situation to operator error. Of eighteen leading electronics manufacturers in Greenpeace 's Guide to Greener Electronics (October 2010), Motorola shared sixth place with competitors Panasonic and Sony . Motorola scored relatively well on
1160-562: A chip for a terminal they were designing, the Datapoint 2200 —fundamental aspects of the design came not from Intel but from CTC. In 1968, CTC's Vic Poor and Harry Pyle developed the original design for the instruction set and operation of the processor. In 1969, CTC contracted two companies, Intel and Texas Instruments , to make a single-chip implementation, known as the CTC 1201. In late 1970 or early 1971, TI dropped out being unable to make
1276-471: A complete computer processor could be contained on several MOS LSI chips. Designers in the late 1960s were striving to integrate the central processing unit (CPU) functions of a computer onto a handful of MOS LSI chips, called microprocessor unit (MPU) chipsets. While there is disagreement over who invented the microprocessor, the first commercially available microprocessor was the Intel 4004 , released as

This chip could also arguably lay claim to be one of the first microprocessors or microcontrollers having ROM , RAM and a RISC instruction set on-chip. The layout for the four layers of the PMOS process was hand drawn at x500 scale on mylar film, a significant task at the time given the complexity of
1508-468: A courtroom demonstration computer system, together with RAM, ROM, and an input-output device. In 1968, Garrett AiResearch (who employed designers Ray Holt and Steve Geller) was invited to produce a digital computer to compete with electromechanical systems then under development for the main flight control computer in the US Navy 's new F-14 Tomcat fighter. The design was complete by 1970, and used
1624-497: A decades-long legal battle with the state of California over alleged unpaid taxes on his patent's windfall after 1990, which would culminate in a landmark Supreme Court case addressing states' sovereign immunity in Franchise Tax Board of California v. Hyatt (2019) . Along with Intel (who developed the 8008 ), Texas Instruments developed in 1970–1971 a one-chip CPU replacement for the Datapoint 2200 terminal,
1740-782: A four-function calculator. The TMS1802NC, despite its designation, was not part of the TMS 1000 series; it was later redesignated as part of the TMS 0100 series, which was used in the TI Datamath calculator. Although marketed as a calculator-on-a-chip, the TMS1802NC was fully programmable, including on the chip a CPU with an 11-bit instruction word, 3520 bits (320 instructions) of ROM and 182 bits of RAM. In 1971, Pico Electronics and General Instrument (GI) introduced their first collaboration in ICs,
1856-550: A further 4,000 job cuts in June and another 20% cut of its research division a few days later. In July 2008, a large number of executives left Motorola to work on Apple Inc. 's iPhone . The company's handset division was also put on offer for sale. Also that month, analyst Mark McKechnie from American Technology Research said that Motorola "would be lucky to fetch $ 500 million" for selling its handset business. Analyst Richard Windsor said that Motorola might have to pay someone to take
1972-541: A major advance over Intel, and two year earlier. It actually worked and was flying in the F-14 when the Intel 4004 was announced. It indicates that today's industry theme of converging DSP - microcontroller architectures was started in 1971. This convergence of DSP and microcontroller architectures is known as a digital signal controller . In 1990, American engineer Gilbert Hyatt was awarded U.S. Patent No. 4,942,516, which
2088-560: A more central player in the early stages of the GSM standardization process in 1987. With this addition Motorola strengthened its position in Europe significantly. As Motorola's European development arm, Storno developed a GSM terminal in 1992. On January 29, 1988, Motorola sold its Arcade, New York facility and automotive alternators, electromechanical speedometers and tachometers products to Prestolite Electric . In 1996, Motorola released
2204-500: A professor. Shannon is considered "The Father of Information Theory". In 1951 Microprogramming was invented by Maurice Wilkes at the University of Cambridge , UK, from the realisation that the central processor could be controlled by a specialised program in a dedicated ROM . Wilkes is also credited with the idea of symbolic labels, macros and subroutine libraries. Following the development of MOS integrated circuit chips in
2320-550: A reliable part. In 1970, with Intel yet to deliver the part, CTC opted to use their own implementation in the Datapoint 2200, using traditional TTL logic instead (thus the first machine to run "8008 code" was not in fact a microprocessor at all and was delivered a year earlier). Intel's version of the 1201 microprocessor arrived in late 1971, but was too late, slow, and required a number of additional support chips. CTC had no interest in using it. CTC had originally contracted Intel for
2436-451: A single MOS LSI chip in 1971. The single-chip microprocessor was made possible with the development of MOS silicon-gate technology (SGT). The earliest MOS transistors had aluminium metal gates , which Italian physicist Federico Faggin replaced with silicon self-aligned gates to develop the first silicon-gate MOS chip at Fairchild Semiconductor in 1968. Faggin later joined Intel and used his silicon-gate MOS technology to develop

Vadász at the time of the MCS-4 development but Vadász's attention was completely focused on the mainstream business of semiconductor memories so he left the leadership and the management of the MCS-4 project to Faggin, who was ultimately responsible for leading the 4004 project to its realization. Production units of
2668-676: A small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU). The IC is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock -driven, register -based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory , and provides results (also in binary form) as output. Microprocessors contain both combinational logic and sequential digital logic , and operate on numbers and symbols represented in

In April 1970, Intel hired Italian engineer Federico Faggin as project leader, a move that ultimately made the single-chip CPU final design a reality (Shima meanwhile designed the Busicom calculator firmware and assisted Faggin during the first six months of
2900-405: A special circuit triggered the ignition system in synchronization with the reference pulses from the engine. Third, the processor was not allowed to start until the internal voltage was stabilized above 10 volts. The EEC-II controlled air-fuel ratio via Ford's model 7200 Variable Venturi (VV) Carburetor, the last carburetor designed and built by Ford US. In it, the air-fuel ratio was controlled by
3016-434: A stepper motor that operated a rack which moved a pintle that opened and closed the float bowl vent. When closed, no air could enter the bowl, causing the fuel mixture to be lean. When open, the fuel mixture was rich. Each carburetor was hand-calibrated in a pressure-controlled room. Although there was much in common "inside the box", the size, shape and main connector were different between EEC I and II. This processor design
3132-612: A system can provide control strategies that would be impractical to implement using electromechanical controls or purpose-built electronic controls. For example, an internal combustion engine's control system can adjust ignition timing based on engine speed, load, temperature, and any observed tendency for knocking—allowing the engine to operate on a range of fuel grades. The advent of low-cost computers on integrated circuits has transformed modern society . General-purpose microprocessors in personal computers are used for computation, text editing, multimedia display , and communication over

An 8- or 16-bit processor may be selected over a 32-bit processor for system on a chip or microcontroller applications that require extremely low-power electronics , or are part of a mixed-signal integrated circuit with noise-sensitive on-chip analog electronics such as high-resolution analog to digital converters, or both. Some people say that running 32-bit arithmetic on an 8-bit chip could end up using more power, as
3364-417: A throttle body attached to a traditional intake manifold in the center valley of the 5.0 liter (302 cid) engine. The processor was designed and manufactured by Motorola . It featured an 8-bit data length, a 10-bit instruction length and a 13-bit address length. The address space was "paged", meaning you could not directly address all of the address space without special instructions. There were 4 pages. Page 0

Memory quickly grew to 2 - 8k/128 MROM/RAM chips and then a separate 32K MROM and 1K RAM. Bus loading limited the design to 2 external memory devices. Intel only manufactured chips, not modules. Eventually there was a unique MBUS UVEPROM designed and manufactured by Intel. Motorola and Ford Electronics Division designed and manufactured

Because the clone makers' licenses were valid only for Apple's System 7 operating system, Apple's release of Mac OS 8 left the clone manufacturers unable to ship a current Mac OS version without negotiation with Apple. A heated telephone conversation between Jobs and then Motorola CEO Christopher Galvin resulted in
4988-519: The binary number system. The integration of a whole CPU onto a single or a few integrated circuits using Very-Large-Scale Integration (VLSI) greatly reduced the cost of processing power. Integrated circuit processors are produced in large numbers by highly automated metal–oxide–semiconductor (MOS) fabrication processes , resulting in a relatively low unit price . Single-chip processors increase reliability because there are fewer electrical connections that can fail. As microprocessor designs improve,

It was an ambitious and well thought-through 8-bit design that was source compatible with the 6800 , and implemented using purely hard-wired logic (subsequent 16-bit microprocessors typically used microcode to some extent, as CISC design requirements were becoming too complex for pure hard-wired logic). Another early 8-bit microprocessor
5220-465: The 4004 were first delivered to Busicom in March 1971 and shipped to other customers in late 1971. The Intel 4004 was followed in 1972 by the Intel 8008 , intel's first 8-bit microprocessor. The 8008 was not, however, an extension of the 4004 design, but instead the culmination of a separate design project at Intel, arising from a contract with Computer Terminals Corporation , of San Antonio TX, for
5336-433: The 4004, along with Marcian Hoff , Stanley Mazor and Masatoshi Shima in 1971. The 4004 was designed for Busicom , which had earlier proposed a multi-chip design in 1969, before Faggin's team at Intel changed it into a new single-chip design. Intel introduced the first commercial microprocessor, the 4-bit Intel 4004, in 1971. It was soon followed by the 8-bit microprocessor Intel 8008 in 1972. The MP944 chipset used in

This chip was never sold commercially, but a close variation, the 8096 , was extremely popular. The major difference between these two chips was the external instruction/data bus. Ford wanted to minimize the number of pins used for input and output so Intel designed a unique bus (MBUS) that multiplexed address and data onto an 8 bit bus. Several additional control lines were used for transferring information on this bus. Because of

(2007), The scientific papers and literature published around 1971 reveal that the MP944 digital processor used for the F-14 Tomcat aircraft of the US Navy qualifies as the first microprocessor. Although interesting, it was not a single-chip processor, as
8004-476: The earliest adopters of digital electronics on a race car. These EEC-IV were used on the Ford/Cosworth 1.5L turbo Formula 1 engine in 1985. This engine with the EEC-IV was used by Haas/FORCE F1 a.k.a. Hass/Lola. This team employed both Ross Brawn and Adrian Newey. Additional performance needs drove Ford Electronics to develop an enhanced microprocessor named the 8065 building on EEC-IV technology. Memory
8120-461: The early 1960s, MOS chips reached higher transistor density and lower manufacturing costs than bipolar integrated circuits by 1964. MOS chips further increased in complexity at a rate predicted by Moore's law , leading to large-scale integration (LSI) with hundreds of transistors on a single MOS chip by the late 1960s. The application of MOS LSI chips to computing was the basis for the first microprocessors, as engineers began recognizing that
8236-453: The famous words "That's one small step for man, one giant leap for mankind" from the Moon on a Motorola transceiver. In 1973, Motorola demonstrated the first hand-held portable telephone. In 1974, Motorola introduced its first microprocessor, the 8-bit MC6800 , used in automotive, computing and video game applications. The 6800 was the basis for the more popular MOS Technology 6502 which
8352-493: The first true microprocessor built on a single chip, priced at US$ 60 (equivalent to $ 450 in 2023). The claim of being the first is definitely false, as the earlier TMS1802NC was also a true microprocessor built on a single chip and the same applies for the - prototype only - 8-bit TMX 1795. The first known advertisement for the 4004 is dated November 15, 1971, and appeared in Electronic News . The microprocessor
8468-548: The implementation). Faggin, who originally developed the silicon gate technology (SGT) in 1968 at Fairchild Semiconductor and designed the world's first commercial integrated circuit using SGT, the Fairchild 3708, had the correct background to lead the project into what would become the first commercial general purpose microprocessor. Since SGT was his very own invention, Faggin also used it to create his new methodology for random logic design that made it possible to implement
8584-459: The instruction. A single operation code might affect many individual data paths, registers, and other elements of the processor. As integrated circuit technology advanced, it was feasible to manufacture more and more complex processors on a single chip. The size of data objects became larger; allowing more transistors on a chip allowed word sizes to increase from 4- and 8-bit words up to today's 64-bit words. Additional features were added to
8700-565: The intellectual property of Sendo for $ 30,000 and paid £362,575 for the plant, machinery and equipment. In June 2006, Motorola acquired the software platform ( AJAR ) developed by the British company TTP Communications plc. Later in 2006, the firm announced a music subscription service named iRadio . The technology came after a break in a partnership with Apple Computer (which in 2005 had produced an iTunes compatible cell phone ROKR E1 , and most recently, mid-2007, its own iPhone ). iRadio
8816-589: The largest single market for semiconductors so Pico and GI went on to have significant success in this burgeoning market. GI continued to innovate in microprocessors and microcontrollers with products including the CP1600, IOB1680 and PIC1650. In 1987, the GI Microelectronics business was spun out into the Microchip PIC microcontroller business. The Intel 4004 is often (falsely) regarded as
8932-484: The latest system with a PowerPC microcontroller used by Ford Motor Company , utilizing mostly the CAN bus and Ford's proprietary MS-CAN architecture. Other variations currently exist, but no additional information about them is available at this time. Microprocessor A microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or
9048-488: The magazine Radio-Electronics in 1974. This processor had an 8-bit data bus and a 14-bit address bus. The 8008 was the precursor to the successful Intel 8080 (1974), which offered improved performance over the 8008 and required fewer support chips. Federico Faggin conceived and designed it using high voltage N channel MOS. The Zilog Z80 (1976) was also a Faggin design, using low voltage N channel with depletion load and derivative Intel 8-bit processors: all designed with
9164-452: The methodology Faggin created for the 4004. Motorola released the competing 6800 in August 1974, and the similar MOS Technology 6502 was released in 1975 (both designed largely by the same people). The 6502 family rivaled the Z80 in popularity during the 1980s. A low overall cost, little packaging, simple computer bus requirements, and sometimes the integration of extra circuitry (e.g.
9280-408: The microprocessor and the payment of substantial royalties through a Philips N.V. subsidiary, until Texas Instruments prevailed in a complex legal battle in 1996, when the U.S. Patent Office overturned key parts of the patent, while allowing Hyatt to keep it. Hyatt said in a 1990 Los Angeles Times article that his invention would have been created had his prospective investors backed him, and that
9396-445: The mid-1970s on. The first use of the term "microprocessor" is attributed to Viatron Computer Systems describing the custom integrated circuit used in their System 21 small computer system announced in 1968. Since the early 1970s, the increase in capacity of microprocessors has followed Moore's law ; this originally suggested that the number of components that can be fitted onto a chip doubles every year. With present technology, it
9512-404: The modules were designed and assembled by Motorola, Toshiba, or Ford. The designs were functionally equivalent but slightly different components were used. Motorola optimized their design to use as many of their own components as possible. Preliminary design work in EEC-IV started even before EEC-III was in production. Over time, there were many different modules designed around this processor. It
9628-537: The modules. After several years of Intel being the sole supplier of processor chips, Ford persuaded Intel to share the design with Motorola and allow them to produce 8061 chips, but only for consumption by Ford. Over the years, there were many variations of EEC-IV modules depending on the number of engine cylinders and the types and quantities of inputs and outputs. There were even a series of special EEC-IV modules designed for use in Formula 1 race cars, making Ford one of
9744-680: The name "Motorola" by linking "motor" (from motor car) with "ola" (from Victrola ), which was also a popular ending for many companies at the time, e.g. Moviola , Crayola . The company sold its first Motorola branded radio on June 23, 1930, to Herbert C. Wall of Fort Wayne, Indiana, for $ 30. The Motorola brand name became so well known that Galvin Manufacturing Corporation later changed its name to Motorola, Inc., in 1947. Galvin Manufacturing Corporation began selling Motorola car-radio receivers to police departments and municipalities in November 1930. The company's first public safety customers (all in
9860-757: The packaged PDP-11/03 minicomputer —and the Fairchild Semiconductor MicroFlame 9440, both introduced in 1975–76. In late 1974, National introduced the first 16-bit single-chip microprocessor, the National Semiconductor PACE , which was later followed by an NMOS version, the INS8900 . Next in list is the General Instrument CP1600 , released in February 1975, which was used mainly in
9976-522: The processor architecture; more on-chip registers sped up programs, and complex instructions could be used to make more compact programs. Floating-point arithmetic , for example, was often not available on 8-bit microprocessors, but had to be carried out in software . Integration of the floating-point unit , first as a separate integrated circuit and then as part of the same microprocessor chip, sped up floating-point calculations. Occasionally, physical limitations of integrated circuits made such practices as
10092-470: The remainder of Motorola, Inc., which comprised the government and enterprise equipment businesses, would become Motorola Solutions . The split was closed on January 4, 2011. Motorola Mobility was eventually acquired by Google on May 22, 2012. Google later sold Motorola Mobility's cable equipment business to Arris Group in December 2012, and Motorola Mobility itself to Lenovo on October 30, 2014. At
10208-524: The same die as the processor. This CPU cache has the advantage of faster access than off-chip memory and increases the processing speed of the system for many applications. Processor clock frequency has increased more rapidly than external memory speed, so cache memory is necessary if the processor is not to be delayed by slower external memory. The design of some processors has become complicated enough to be difficult to fully test , and this has caused problems at large cloud providers. A microprocessor
10324-440: The smallest embedded systems and handheld devices to the largest mainframes and supercomputers . A microprocessor is distinct from a microcontroller including a system on a chip . A microprocessor is related but distinct from a digital signal processor , a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing . The complexity of an integrated circuit
10440-513: The spark advance for vehicles experiencing pre-ignition (knock). The processor module featured a 10 volt reference for its analog-to-digital converter which was used to gather data from various sensors. This could have been an issue as the available power to the module varied above and below 10 volts during engine cranking. The problem was solved by several steps. First, all sensors used a ratiometric measuring method that ensured accuracy in spite of varying reference voltage. Second, during cranking,
10556-623: The termination of Motorola's clone contract, the discontinuation of the Motorola StarMax, and the long-favored Apple being demoted to "just another customer" mainly for PowerPC CPUs. Apple (and Jobs) did not want Motorola to limit the PowerPC CPU supply so as retaliation, Apple and IBM expelled Motorola from the AIM alliance and forced Motorola to stop producing any PowerPC CPUs, leaving IBM to make all future PowerPC CPUs. However, Motorola
10672-473: The time of its split, Motorola had three divisions: Motorola's handset division recorded a loss of $ 1.2 billion in the fourth quarter of 2007, while the company as a whole earned $ 100 million during that quarter. It lost several key executives to rivals, and the website TrustedReviews called the company's products repetitive and un-innovative. Motorola laid off 3,500 workers in January 2008, followed by
10788-470: The unique nature of the bus, custom memory chips were required. EEC-IV first appeared on the 1983 1.6L EFI, 2.3L High Swirl Combustion (HSC), 2.3L EFI Turbo and 2.8L truck engines. With the Escort, the base engine was the same as all US Escorts, the 1.6L CVH, but featured unique intake and exhaust manifolds in addition to EFI . This was non-sequential EFI , meaning 1/4 of the required fuel for each cylinder
10904-452: The value of World War II military production contracts. Motorola went public in 1943, and became Motorola, Inc. in 1947. At that time Motorola's main business was producing and selling televisions and radios. The last plant was listed in Quincy, Illinois at 1400 North 30th Street where 1,200 employees made radio assemblies for both homes and automobiles. In 1969, Neil Armstrong spoke
11020-574: The venture investors leaked details of his chip to the industry, though he did not elaborate with evidence to support this claim. In the same article, The Chip author T.R. Reid was quoted as saying that historians may ultimately place Hyatt as a co-inventor of the microprocessor, in the way that Intel's Noyce and TI's Kilby share credit for the invention of the chip in 1958: "Kilby got the idea first, but Noyce made it practical. The legal ruling finally favored Noyce, but they are considered co-inventors. The same could happen here." Hyatt would go on to fight
11136-491: The widely varying operating conditions of an automobile. Non-programmable controls would require bulky, or costly implementation to achieve the results possible with a microprocessor. A microprocessor control program ( embedded software ) can be tailored to fit the needs of a product line, allowing upgrades in performance with minimal redesign of the product. Unique features can be implemented in product line's various models at negligible production cost. Microprocessor control of
11252-530: The world in 1940, defense electronics, cellular infrastructure equipment, and mobile phone manufacturing. In the same year, the company built its research and development program with Dan Noble , a pioneer in FM radio and semiconductor technologies, who joined the company as director of research. The company produced the hand-held AM SCR-536 radio during World War II , which was vital to Allied communication. Motorola ranked 94th among United States corporations in
11368-683: The world's first commercial GPRS cellular network to BT Cellnet in the United Kingdom. Motorola also developed the world's first GPRS cell phone. In August 2000, Motorola acquired Printrak International Inc. for $ 160 million. In doing so, Motorola not only acquired computer aided dispatch and related software, but also acquired Automated fingerprint identification system software. With recent acquisitions from that year, Motorola reached its peak employment of 150,000 employees worldwide. Two years later, employment would be at 93,000 due to layoffs and spinoffs. In June 2005, Motorola overtook
11484-456: The wrong vehicle. EEC-III uses a Duraspark III module (brown grommet where wires emerge) and a Duraspark II ignition coil. A resistance wire is used in the primary circuit. The distributors in EEC-III (and later) systems eliminate conventional mechanical and vacuum advance mechanisms. All timing is controlled by the engine computer, which is capable of firing the spark plug at any point within
11600-793: Was a pioneer in cellular telephones. Also known as the Personal Communication Sector (PCS) prior to 2004, it pioneered the "mobile phone" with the first truly mobile "brick phone" DynaTAC , "flip phone" with the MicroTAC as well as the "clam phone" with the StarTAC in the mid-1990s. It had staged a resurgence by the mid-2000s with the RAZR , but lost market share in the second half of that decade. Later it focused on smartphones using Google 's open-source Android mobile operating system. The first phone to use Android 2.0 "Eclair" ,
11716-419: Was also delivered in 1969. The Four-Phase Systems AL1 was an 8-bit bit slice chip containing eight registers and an ALU. It was designed by Lee Boysel in 1969. At the time, it formed part of a nine-chip, 24-bit CPU with three AL1s. It was later called a microprocessor when, in response to 1990s litigation by Texas Instruments , Boysel constructed a demonstration system where a single AL1 formed part of
11832-403: Was based on a 16-bit serial computer he built at his Northridge, California , home in 1969 from boards of bipolar chips after quitting his job at Teledyne in 1968; though the patent had been submitted in December 1970 and prior to Texas Instruments ' filings for the TMX 1795 and TMS 0100, Hyatt's invention was never manufactured. This nonetheless led to claims that Hyatt was the inventor of
11948-460: Was designed by a team consisting of Italian engineer Federico Faggin , American engineers Marcian Hoff and Stanley Mazor , and Japanese engineer Masatoshi Shima . The project that produced the 4004 originated in 1969, when Busicom , a Japanese calculator manufacturer, asked Intel to build a chipset for high-performance desktop calculators . Busicom's original design called for a programmable chip set consisting of seven different chips. Three of
12064-572: Was expanded from 64K to 1 megabyte, speed tripled, and I/O more than doubled. Additional interrupts and improved time controlled I/O allowed continued use of EEC-IV code and extended the family lifetime to almost 20 years in production. European Ford Diesel Duratorq engines (all TDDi and TDCi starting with model year 2000) used EEC-V DPC-xxx series, which used variant of Intel i196 microcontroller with 28F200 flash memory. The EEC-V DPC ECUs were later replaced by Delphi, Bosch EDC16, Siemens SID80x/SID20x, or Visteon DCU ECUs. Visteon Levanta 'Black Oak' PCM
12180-425: Was for normal (background) code. Page 1 was for interrupt code. Page 2 was also for background, but could only be accessed by a special "Jump Page" instruction from page 0. Page 3 was used to store parametric ("calibration") data or additional interrupt level code. This chip was never sold commercially. Like EEC-I and -II, all code was written in assembly language. The processor chips were manufactured by Motorola, and
12296-654: Was injected into the intake manifold, near the intake valve for each cylinder firing. The first EEC-IV module was different from future modules. It had a unique "edge card" connector intended to reduce cost versus the EEC I/II/II pin-and-socket connectors, but was quickly abandoned due to poor reliability. It utilized a 40 pin DIP IC package which limited the number of inputs/outputs. It also used only 1 memory chip which contained 8K bytes of MROM instructions/data and 128 addition bytes of RAM. All subsequent EEC-IV modules used
12412-549: Was later reinstated into the alliance in 1998. In 1998, Motorola was overtaken by Nokia as the world's biggest seller of mobile phone handsets. In 1999, Motorola separated a portion of its semiconductor business—the Semiconductor Components Group (SCG)-- and formed onsemi (then ON Semiconductor ), whose headquarters were located in Phoenix, Arizona . In June 2000, Motorola and Cisco supplied
12528-563: Was made by former Motorola employees. That same year, Motorola sold its television business to the Japan-based Matsushita – the parent company of Panasonic . In 1980, Motorola's next generation 32-bit microprocessor, the MC68000 , led the wave of technologies that spurred the computing revolution in 1984, powering devices from companies such as Apple , Commodore , Atari , Sun , and Hewlett-Packard . In September 1983,
12644-540: Was no "stack" for subroutine calls and returns. Rather the Instruction Pointer Register was "swapped" with another register that had been previously filled with the address of the target subroutine. Returning was accomplished by swapping back. All code was written in assembly language. Another feature on the EEC I/II modules was the use of a separate memory module that bolted to the housing of
12760-432: Was not the Intel 4004 – they both were more like a set of parallel building blocks you could use to make a general-purpose form. It contains a CPU, RAM , ROM , and two other support chips like the Intel 4004. It was made from the same P-channel technology, operated at military specifications and had larger chips – an excellent computer engineering design by any standards. Its design indicates
12876-492: Was significantly upgraded as a candidate for use in EEC-III but was not chosen. This system was used on certain 1980-83 vehicles. There were two different EEC-III modules; one for use with a feedback carburetor, and one for use with Ford's "Central" throttle-body fuel injection system. The module size and shape were approximately the same as the EEC-II and still utilized the external memory module. The two modules had differently keyed connectors to prevent accidental insertion in
12992-932: Was split into two independent public companies, Motorola Mobility and Motorola Solutions , on January 4, 2011. The reorganization was structured with Motorola Solutions legally succeeding Motorola, Inc., and Motorola Mobility being spun off. Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Motorola's home and broadcast network products included set-top boxes , digital video recorders , and network equipment used to enable video broadcasting, computer telephony, and high-definition television . Its business and government customers consisted mainly of wireless voice and broadband systems (used to build private networks), and public safety communications systems like Astro and Dimetra . These businesses, except for set-top boxes and cable modems , became part of Motorola Solutions. Motorola's wireless telephone handset division
13108-471: Was the Signetics 2650 , which enjoyed a brief surge of interest due to its innovative and powerful instruction set architecture . A seminal microprocessor in the world of spaceflight was RCA 's RCA 1802 (aka CDP1802, RCA COSMAC) (introduced in 1976), which was used on board the Galileo probe to Jupiter (launched 1989, arrived 1995). RCA COSMAC was the first to implement CMOS technology. The CDP1802
13224-442: Was the only commercially available chip to feature all four mathematical functions (addition, subtraction, multiplication and division) at the time. The choice of 12 bits was not accidental. For accuracy, it was determined that formulas needed to be able to resolve 1 part in 1000 or about 10 bits. Another bit was required for sign. This, logically, was rounded up to 12 bits which also resulted in an address space of 16 kilo-words. There
13340-464: Was to have many similarities with existing satellite radio services (such as Sirius and XM Radio ) by offering live streams of commercial-free music content. Unlike satellite services, however, iRadio content would be downloaded via a broadband internet connection. However, iRadio was never commercially released. Greg Brown became Motorola's chief executive officer in 2008. In October 2008, Motorola agreed to sell its Biometrics business to Safran ,
13456-469: Was used because it could be run at very low power , and because a variant was available fabricated using a special production process, silicon on sapphire (SOS), which provided much better protection against cosmic radiation and electrostatic discharge than that of any other processor of the era. Thus, the SOS version of the 1802 was said to be the first radiation-hardened microprocessor. The RCA 1802 had
