摘　　要：H.264视频压缩标准凭借高压缩比和较好的图像质量,己经作为一种新型的标准被广泛接受。由于H.264的解码复杂度很高,软件实现难以满足实时性的要求,所以需要采用硬件解码。本文提出了一种针对H.264视频编码标准的可变长指数哥伦布码解码的硬件设计结构,给出了一种系统解码时间消耗与系统资源占用较少的硬件设计方案,最后给出了设计最终的仿真以及后端设计的结果。Based on its high compression ratio and better image quality,the new standard of video compression, H. 264 has been widely accepted and used in many applications. Because the decoding of H. 264 is very complex,software implementation can＇t decode the video in real - time. We implement the H. 264 decoder in hardware. We propose a hardware architecture of Exp-Golomb decoder for H. 264. This design has less decoding time and uses less logical resource. Finally the simulation and back end design results are also presented in this paper.
