基于单指令多数据流技术的视频信息处理优化

Based on Single Instruction More Data Dlow Technology of Video Information Processing Optimization

文章以H.264编码为例,首先对单指令多数据指令系统进行了简单介绍,并在该技术基础之上,分别从H.264整数离散余弦变换、量化以及运动估计等方面分析和探讨了依托于单指令多数据流技术的视频信息处理的优化方式,与之前的程序编码技术相比较而言,经过优化处理的程序编码速率提升了数倍。

This paper to H.264 encoded as an example, the first single instruction to mulhple data instruction system is simply introduced, and in the technical basis, separately from H.264 integer discrete cosine transform, quantitative motion estimation and analyzes and discusses the single instruction relying on in more data flow of video information processing technology of optimization methods, and the program before encoding technology in comparison, after optimization procedure of treatment encoding speed up several times.
