H．264标准是ITU．T视频编码专家组和ISO IEC活动图像专家组共同组成的联合视频组开发的新一代视频压缩标准。H．264高效的编码效率建立在其高复杂度的编码算法基础上，而采用具有较强并行处理能力的C64x+DSP芯片的达芬奇(Davinci)技术平台，则以较高的运算性能和丰富的外围接口成为目前实现视频应
用系统的理想平台。本文对H．264编码算法的帧间及帧内预测算法进行改进，并进行了H．264编码器在DM6437平台上的移植和优化。-H．264 was jointly proposed by ITU—T Video Coding Experts Group and IS0／IEC
Moving Picture Experts Group．Compared with other former standards．H．264 has
incomparable advantage in the compression rate，video quality and the robust network stream．However，H．264 algorithm has high encoding efficiency but also high complexity，Davinci technology platform combines the DSP chip with C64x+
processor，providing a strong parallel processing capability．It has presently become an ideal platform in the area of video frequency application for its high computing
performance and rich peripheral interface．This paper provided a improved inter and intra flame prediction algorithm，furthermore transplanted and optimized the H．264
