摘　　要：基于H.264视频编码标准和多核DSP ADSP-BF561的结构特点,提出了一种H.264并行编码方案。这种方案将输入视频分为两个相对独立的Slice编码,适应该DSP的同构双核结构,充分发挥了DSP的处理性能。实验结果表明,该并行方案在几乎不降低图像质量的情况下,编码速度提高了40%左右。A scheme for H.264 parallel coding based on the H.264 video coding standard and the structural characteristics of multi-core DSP ADSP-BF561 is presented.In the scheme,the video is divided into two relatively independent slices to code so as to adapt to which has same structure of dual cores to bring the DSP into full play.The experimental results show that this method improves encoding speed by 40% without degrading the image quality.
