Huawei HiSilicon self-developed non-smart ATV TV chip: 28nm process with Lite OS


Early TVs were born in the era of CRT picture tubes, and the picture was displayed by emitting electron beams through an electron gun. There are requirements for the tube neck distance of the picture tube. The larger the screen, the larger the volume of the TV. Now, TVs have entered the era of LCD flat panels and OLEDs, and the visual experience brought by display technology is becoming clearer, more realistic and immersive.

However, on a global scale, there are still many areas that have not completed or even planned to carry out the digital transformation of TV signals. At the same time, there are also many families who cannot afford the cost of smart TV. According to statistics, about 30% of the TV market is non-smart TV every year, and there is no performance requirement. High, the size is generally below 40 inches, and the resolution is 1080P or below.

Huawei Shanghai HiSilicon said that HiSilicon smart media products have recently launched a boutique chip for the non-smart ATV market, which can receive analog TV signals, support external HDMI, VGA, CVBS and other input device signals, and support USB playback.

Huawei HiSilicon self-developed non-smart ATV TV chip: 28nm process with Lite OS

The non-smart ATV chip uses 28nm process, with self-developed CPU, and integrates the screen timing controller (TCON) module. The picture quality level is fully improved, and the self-developed SWS sound effect is integrated. Truly high integration, high performance; with self-developed real-time operating system Lite OS.

In this product range, due to its simpler functions and more sensitive to price, more advanced processes are generally not required. The current mainstream processes are still 40nm and above . HiSilicon’s ATV chip integrates self-developed CPU and TCON functions, upgrades the image quality processing module, and improves the production process to 28nm:

  • The overall performance is more than 20% higher than other products in the industry, and the heat dissipation performance is extremely good
  • The TCON function is integrated, so that the SoC can be directly matched with the screen, effectively reducing the cost of the whole machine
  • The chip has been adapted to all FHD/HD screens currently on the market in advance, effectively reducing the development and adaptation work of TV manufacturers
Secondly, the chip uses self-developed lightweight real-time Lite OS operating system, ultra-small kernel (<100K) low memory usage, real-time operating system can support multi-process synchronization processing, support dynamic loading, scattered loading, faster running speed, can provide Users bring better operating experience. Especially in some places with unstable circuits and frequent power outages, LiteOS's shorter boot time can help customers not miss exciting content.

This boutique chip also provides self-developed SWS sound effects for free. The overall effect of SWS sound effects can be comparable to mainstream surround sound effects. Combined with the improvement of chip image quality, it brings a better audio and video experience.
