Actions Semiconductor Co. Ltd. ( Chinese : 炬力集成 ; pinyin : Jùlì Jíchéng ) is a Chinese fabless semiconductor company founded in 2000 and headquartered in Zhuhai , Guangdong province and has offices in both Shanghai and Shenzhen . The company has about 600 employees and designs SoCs for tablets , digital audio players , photo viewers and related products.
7-401: In 2008 Actions Semiconductor acquired Hi-Trend Technology Co. Ltd's 2D graphics technology. The company acquired Mavrix technology in 2010. In November 2011, Niccolo Chen stepped down as CEO, and was replaced by Zhenyu Zhou who was Senior Vice President at the time, and was the founder of Mavrix in 2005. On 12 September 2016, Actions Semiconductor announced their merger with Starman Limited, which
14-444: A jumble of hard to identify internal designs, all employing non-mutually-interchangeable firmwares. Some models have additional features, such as: Available utilities for Microsoft Windows include an ACT to WAV file converter (for files recorded on the device), a basic desktop editor to enter contact details for the device's phone book function and device drivers for Windows 98 . An 8 cm CD-ROM containing some or all of these
21-685: Is comprised by a large amount of then-inexpensive handheld digital audio players . The players were mainly widespread around 2005–2006 but the series continued for years afterwards, blurring into that of so-called " MP4 players " employing S1 and competing architectures. Despite being primarily defined by the use of a system-on-a-chip of one of the Actions brands usually of the ATJ20xx series and some common core features, S1 products vary widely in software and hardware as well as design (including lookalikes and even counterfeits of other players), leading to
28-498: Is included with some versions of the device. There are also tools developed by individuals under the Open-Source license, such as s1res ans s1clone that allow the consumer to modify its device by changing bitmaps and text. By using decompilers, it is possible to add and replace features of the device, steps that were described on the s1mp3.org wiki page. The firmware used in various S1 MP3 players differs significantly, but this
35-474: Is not widely understood. Problems have arisen as consumers have attempted to upgrade their players using incompatible firmware with a higher version number. This can damage the players almost permanently. However, a 'dead' player can sometimes be recovered by opening it, shorting some pins and uploading a full firmware from the PC. Guides on recovering the players were available on a unofficial website s1mp3.org that
42-588: Was completed on 9 December 2016. The following is a list of system-on-chips developed and marketed by Actions Semiconductor, mainly targeting tablets. S1 MP3 players use chipsets designed by Actions. In 2012, Actions Semiconductor produced the ATM7029 which is a quad-core ARM Cortex-A5 -based SoC using Vivante Corporations GC1000 GPU . This SoC has been used in the Ainol NOVO10 Hero II tablet and other low end tablets. For Q2 2014, Actions
49-602: Was reported to be fourth largest supplier of tablet processors to the Chinese market. At one point, Actions was sued by SigmaTel with SigmaTel prevailing. The findings were that Actions infringed upon SigmaTel by directly copying the ASICs designed by SigmaTel, once a world leader in the MP3 ASIC market. SigmaTel later was sold to Freescale Semiconductor . S1 MP3 player The loosely defined category of S1 MP3 players
