Shenzhen Hisilicon production cheap H.264 codec LSI

(Hisilicon Technologies Co. Shenzhen Hisilicon Ltd) began production supply H.264 LSI codec Hi3510". The biggest feature of the product is "cheaper than the MPEG-4 codec LSI" (Japanese distributor Silicondevice). Can be in accordance with the H.264 specification SDTV (720 x 480 pixels, 30 frames / s) video codec.

Hisilicon Hi3510 development is a venture enterprise founded in October 2004, is separated from the Chinese communications equipment giant HUAWEI technology in. The development of the Hi3510 is the company's first official export products (Silicondevice).

Hi3510 integrates the CPU kernel "ARM926EJ-S", DSP and H.264 codec accelerator. At the same time, it is equipped with 10/100Base-T Mac layer processing circuit, etc., so that only a small number of external components can constitute a IP camera and IP videophone terminal (Silicondevice). The IP camera here refers to the direct access to the Internet video monitoring head. According to Silicondevice, China has 3 companies decided to adopt Hi3510, is expected to be a company in Taiwan will be.

The supported protocol is Baseline Profile (Level 2.2). The maximum data rate of SDTV video coding with H.264 specification is 4Mbit/ seconds. And the connection between the external memory bandwidth of about 100MHz. Normal operating requirements of the minimum memory capacity of 32MB. Standard power consumption of 700mW. Using 400 pin LFBGA package, the overall size of 19mm * 19mm * 1.36mm. The working temperature is - 25 DEG C 85. Design process for the 130nm, power supply voltage includes 1.2V, 2.5V and 3.3V three.

In addition, Hi3510 also supports H.263, H.261, JPEG and Windows Media Audio audio codec. The production plan to further expand the Hass semiconductor interface circuit of the Hi3511 in the first quarter of 2007 to the second quarter". New interfaces include USB2.0, IEEE802.11b/g and UWB.
