摘　　要：在DM642 EVM上实现了MPEG-4视频编解码算法,并对算法程序进行了优化。实验结果表明,经过优化的MPEG-4算法程序,在分辨率为720×576进行实时采集时,可以达到28F/S的实时要求。The MPEG- 4 video encode/decode algorithm was implemented based on DM642 EVM, and optimized the program of MPEG - 4 algorithm. Experimental results show that the optimized algorithm program could measure up real-time requirements of 28F/S, which was real-time capture in the resolution of 720 × 576.
