摘　　要：提出了基于TMS320DM642的视频处理系统硬件设计方案。视频处理系统主要包括存储器模块的设计,JTAG接口的设计、电源模块的设计、视频输入输出模块的设计、以太网接口的设计以及报警电路的设计等。同时介绍了系统的调试过程,主要有存储器模块的调试、静态图像的采集、视频显示模块的调试、报警模块的调试以及以太网模块的调试。调试结果表明,该系统可以用于图像采集和视频处理的各种场合。与传统的视频处理系统相比,该系统特有的报警功能增强了系统的实用性。A video processing system based on TMS320DM642 was proposed, mainly including memory module, JTAG interface, power module, video input and output module, Ethernet interface and alarm circuit Meantime, the debugging process of every module was introduced, including the following debugging, collecting of the static image, video displaying, debugging of the alarm and ethernet module. The system could be used in various fields such as image capture and video processing. Compared with the traditional video processing system, this system has an additional alarm function, therefore its practicability is improved.
