摘要
分析了基于TMS320DM6437平台的H.264/AVC编码器,对H.264/AVC编码器结构进行了适当的调整,对代码中大数据量搬移部分进行EDMA优化。使编码器的高速缓冲存储器(cache)命中率提高了20%～30%,编码速率提高了3～4f/s(帧/秒)。
In this paper, H.264/AVC codec is analyzed based on TMS320DM6437, the structure of the encoder is adjusted and the part of the codec with large amount of data transfer is optimized. The cache hits rate is improved significantly by 20%-30%, and the whole encoder velocity is enhanced by 3-4 frames per second.
