摘　　要：针对TI推出的高端专用视频处理芯片TMS320DM642和视频解码芯片TVP5150构建的嵌入式视频监控系统,介绍了DM642的类/微型驱动模型,在此基础上设计了视频采集底层设备驱动程序,并对DM642在图像采集时产生的分屏现象提出了解决办法。本驱动程序已在视频监控系统中得到应用,运行稳定。Aimed at embedded video surveillance system consisted of high-powered video processing chip TMS320DM642 and video decoder TVP5150 of TI, this paper introduces the Class/Mini-Driver Module of DM642, and designs the device driver programs for video capturing. Further more, it provides the solution of splitting-screen problem when DM642 is capturing video. This driver program has been applied to the video surveillance system and testing result indicates that this program runs stably.
