摘　　要：文章为实现基于TMS320DM6446的H.264视频编码器的实时性能,提出一系列优化方法.首先描述X264代码向TMS320DM6446平台的移植过程,然后从项目级优化、指令级优化和算法级优化等几个方面提出优化实现方案.实验结果表明:对于CIF格式的视频,优化后的H.264编码器可以达到24帧/s以上的编码速度,基本满足视频监控系统中编码器的需求.In order to achieve the real-time performance of H.264 video encoder based on TMS320DM6446,a series of optimization methods have been presented.First of all,it described X264 platform code porting to the TMS320DM6437,then several implementation techniques for optimization were presented in this paper from several aspects,including project optimization,instruction level optimization and algorithm optimization.The experimental results show that,for the video sequences with CIF format,the optimized version of H.264 encoder can achieve the encoding rate of more than 24 frames per second,which is basically to meet the needs of the encoder in video monitoring system.
