H.264基本档次码流解析的专用处理器设计

Specific Processor Design for Bit-stream Decoding in H.264 Baseline Profile

针对解析H.264基本档次码流提出一种专用处理器的设计方案,它采用软/硬件联合设计的方法。使硬件电路解码模块可实现每个时钟周期从码流中解析出1个码字的处理速度,比采用树形结构的纯软件方案提高了50倍。

By combining the hardware and software designs, a specific processor for bit-stream decoding in H.264 baseline profile is proposed. The hardware decoding module can decode one symbol in bit-stream per cycle. And the proposed design is 50 times faster than tree-based software solution.
