简要介绍了AVS视频编码标准的主要特点以及单指令多数据（SIMD）汇编指令集运算优势，通过分析AVS参考解码器软件的性能以及造成解码器速度瓶颈的原因，提出了基于SIMD汇编指令的优化方案，最终实现了基于PC的高清AVS视频实时解码。

英文摘要：

In this paper, the video compression standard AVS and the advantages of assembly language SIMD are introduced. Through analyzing the speed bottleneck of the reference AVS decoder program, an optimization method is proposed to accelerate decoding speed. Experimental results show the proposed scheme can significantly improve decoder speed, and then high definition video is finally decoded on general computer in real time.
