摘要 在TMS320DM643平台上实现H.264基档次编码器的移植与优化显得格外实用和必要。基于对DSP平台的结构特性和H.264的计算复杂度分析,主要从核心算法、数据传输和存储器/Cache使用几方面对H.264编码器进行了优化。实验结果表明,对于C IF格式的视频序列,优化后的H.264编码器能够达到每秒高于24帧的编码速度,满足了视频处理对于实时性的要求。 It is particularly useful and necessary in TMS320DM643 platform to achieve the optimization and transplantation of Baseline Profile of H.264 encoder.Based on the analyzing of structural characteristics of DSP platform and the computational complexity of H.264,the article optimizes the H.264 encoder on core algorithm,data transmission and memory/Cache.Experimental results show that the optimized H.264 encoder can achieve higher than 24 frames per second encoding rate for CIF format video sequences and meet the requirements of video processing for real-time.
