ARM - who does what: Telechips (11)

Telechips is a fairly new company, founded in 2000 and who specialized in chips for the audio world. The company offers SoC ARM and equip their entry-level tablets and Media Center boxes at low cost from China. It is mainly based models and SoC TCC8900 TCC8902. The core CPU is quite old, it is an ARM1176 of ARM.

This core issue and in order simply use the ARMv6 instruction set and is found mainly in the low range or a little old (like smartphones of 2007). In SoC TCC890x, it operates at 500 MHz or 720 MHz, depending on the voltage (1.2 V and 1.5 V) and of course the autonomy expected. For the GPU is a chip, ARM Mali 200 of which is incorporated.

OpenGL ES 2.0 and OpenVG 1.1. Power is not announced, but the video chip is capable of decoding the H.264 1080p and 720p encode. It is particularly used in "Google TV" low-end, based on a classical system Android. The SoC is conventional and is oriented to video: HDMI support (1.3), direct support of DVB-X, SATA, etc..

The TCC890x are engraved in 65nm, a priori by TSMC, the company is fabless. In the future, the company will offer the TCC8800, a chip based on a Cortex A8 core, significantly faster than ARM11.
