摘要
TMS320DM642是TI公司推出的一款具有专用视频接口(Video port)的高性能媒体处理DSP,具有强大的?DSP内核和优化的总线结构。以DM642芯片为数据处理核心,建立了包含视频AD&DA模块、视频处理与通信部分的视频采集处理系统,实现了外部模拟视频信号输入、模/数转换、视频采集、视频处理、数/模转换、视频及目标信息输出的完整功能,并为后续控制平台提供了通用接口。系统使用整体编程化的开发方法,采用部分调试与整机联调的调试方法提高了调试效率,加速了系统的研制。
TMS320DM642 is one of high performance DSPs promoted by TI, with specific video ports. DM642 has powerful DSP inner core and advanced Bus structure. Based on the data processing core DM642 chip, the video collection and processing system was compose of video AD＆DA module, video processing and communication part. The system realized the entire function and provided standard interfaces to next control platform, including analog video signal input, AID conversion, video collection, video processing, D/A conversion, and video reference information output. The system was exploited with whole system programmable method and debugged with both part and whole debugging methods, which improved debug efficiency to speed up system development.
