【摘要】 达芬奇(DaVinci)TMS320DM6446是TI公司的目前最先进的专门面向多媒体应用的专用DSP。基于达芬奇平台,文章对H.264视频压缩标准中的一些核心模块进行了优化。实验结果表明,在保证图像质量及相同率失真性能条件下,图像的平均编码速度提高了104%,基本达到了实时视频编码的要求。更多还原

【Abstract】 DaVinci TMS320DM6446 is the most advanced DSP of TI Corporation currently,which faces the multimedia applications. Based on the DaVinci platform, the article has carried on the optimization to H.264 video compression standard key techniques. Ex- perimental results show that the encoder speed has been improves 104% on average while maintaining the same rate distortion performance, and the realtime encoder has been realized basically.更多还原
