Products

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

Adoption

S1 MP3 players use chipsets designed by Actions. In 2012, Actions Semiconductor produced the ATM7029 which is a quad-core

ARM Cortex-A5 The ARM Cortex-A5 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2009. Overview The Cortex-A5 is intended to replace the ARM9 and ARM11 cores for use in low-end devices. The Cortex-A5 offe ...

-based SoC using Vivante Corporations GC1000

GPU A graphics processing unit (GPU) is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobi ...

. This SoC has been used in the Ainol NOVO10 Hero II tablet and other low end tablets. For Q2 2014, Actions was reported to be fourth largest supplier of tablet processors to the Chinese market.

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.
