摘　　要：基于H.264视频编码标准和ADSP-BF561双核的结构特点,结合ADI公司提供的H.264编码库,完成整个编码系统的设计。设计中图像采集采用OV7660,并利用了ADI公司高效、完备的系统级编码库支持,充分考虑了双核DSP的BF561在图像处理中的优异性能进行并行编码。测试结果表明,在BF561上实现H.264视频编码,实现视频流的高质量压缩是完全可行的。Based on H. 264 video coding standard and ADSP- BF561 dual- core structural features,design of the entire coding system is completed combined with H. 264 encodeng library provided by ADI. In this design,with the support of ADI＇s highly efficient,complete system- level encoding library, video is captured by OV7660, meanwhile, excellent performances of the dual - core DSP BF561 is given full consideration in image processing for parallel code. The result shows that it is possible to implement H. 264 video coding on BF561 and high quality compression of video flow.
