摘　　要：介绍了一种将DSP应用于交通参数检测的视频监控系统。系统采用TI公司的DSP处理芯片TM320DM642作为处理器,配合FPGA,视频解码芯片SAA7115H、编码芯片SAA7115,共同来完成对各种交通参数的采集,以及实时车道现场视频数据的远程获取。基于TMS320DM642芯片设计的评估开发板TDS642EVM,给出了处理器TM320DM642的编程方案,在PC上利用Visual C++进行界面设计,对DSP发送的数据进行分析处理与显示,并显示出交通参数的检测结果。A video monitoring system was introduced, in which DSP is applied to detecting traffic parameters. The system consists of TMS320DM642, FPGA, video decoding processor SAA7115H and video encoding processor SAA7115. TMS320DM642 is produced by Texas Instruments Incorporated. The DSP system may complete a variety of traffic parameters, as well as real-time video data from a long-distance. TDS642EVM based on TMS320DM642 chip design was introduced, and the programming plan of the DSP processor TMS320DM642 was presented. Finally, a window was designed by Visual C＋ A- program in a personal computer. The data by DSP were analyzed and displayed. The results of traffic parameters were also displayed.
