摘　　要：针对BF561视频处理系统中视频实时采集和显示这一基础问题,从软硬件两个方面对以ADSP-BF561为核心的视频处理系统中的采集和输出模块的设计和开发方法进行描述。该设计方案在分析系统硬件结构和所采集的视频信号格式的基础上,通过对视频输入/输出工作流程以及BF561片上外设资源的合理安排和配置,保证视频传输的连续性,实现了视频图像的实时采集和显示,为视频处理系统的工作奠定了基础。Tin order to realize the real-time video acquisition and display in the BF561video processing system, the design and developing method of the acquisition and output modules in the video processing system based on ADSP-BF561 are de- scribed in the aspects of hardware and software. According to the analysis of the system hardware architecture and video signal format, the design scheme ensured the continuity of video transmission, realized the real-time acquisition and display of video images, and laid out a foundation for the development of video processing system through the reasonable arrangement and con- figuration of video input/output working flow management and the peripheral resource on BF 561.
