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.[1] The company has about 600 employees and designs SoCs for tablets, digital audio players, photo viewers and related products.


In 2008 Actions Semiconductor acquired Hi-Trend Technology Co. Ltd's 2D graphics technology.[2] 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.[3] On 12 September 2016, Actions Semiconductor announced their merger with Starman Limited,[4][5] which was completed on 9 December 2016.[6]


The following is a list of system-on-chips developed and marketed by Actions Semiconductor, mainly targeting tablets.

  1. ^ The term "Cortex-A9 family" used by Actions is similar to the description used by the company for the CPU cores inside the ATM7029, which have been proven to be Cortex-A5 cores. The ARM Cortex-A5 would be more be accurately described as being "Cortex-A7 family", being slower than but otherwise equivalent to the ARM Cortex-A7, rather than being directly related to the higher-performance ARM Cortex-A9.

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.[20] This SoC has been used in the Ainol NOVO10 Hero II tablet and other low end tablets.[21]

For Q2 2014, Actions was reported to be fourth largest supplier of tablet processors to the Chinese market.[22]

Legal cases

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.[citation needed]
