摘要
为了解决某些领域对视频实时处理系统工作温度范围要求较高的问题,设计了基于TMS320DM642和ADV7179的视频实时处理和显示系统,包括系统硬件和基于DSP/BIOS的软件系统的设计。同时还提出了一种采用TMS320DM642GPIO接口接收MPEG-2传输流(TS)的方案。实验结果较好地验证了设计的合理性和正确性。
In order to meet the high requirements of working temperature range of real-time video processing system in military and other areas, a real-time video processing and displaying system based on TMS320DM642 and ADV7179 is designed, including the design of hardware and software system based on DSP/BIOS. It is also innovative in putting forward a kind of scheme which makes use of TMS320DM642 GPIO interface in receiving MPEG-2 transport streams （TS）. The results of the experiment prove the reasonability and correctness of this design.
