基于DM642的违章车辆实时监控系统的硬件设计

Violation Vehicles Real-time Monitoring System Based on DM642

提出了基于TI公司最新视频处理器DM642的违章车辆实时监控系统的硬件设计方案。DM642使用了C64xx系列高速数字信号处理器的核心处理单元,其运算能力可达48亿条指令每秒(4800MIPS),是目前性能最高的数字信号处理器之一。主要介绍了硬件设计过程。在系统硬件设计部分从工作原理及电路设计方面详细介绍了硬件系统中两个主要的功能模块:外部存储器模块、视频输入输出模块。目前系统的设计和调试工作已经完成。系统使用的DM642处理器,使系统能够适用于各种高复杂度的视频信号处理算法。

This paper introduces a design proposal of the system using the DM642, which is the latest video signal processor from Texas Instruments.The DM642 has a C64x DSP＇s core,which is the one of most advanced DSPs with the high performance of up 4800 million instructions per second （MIPS）.The dissertation introduces the schematic design.The schematic design section introduces the design of two main function module （external memory module,video input/output module） of the system in detail.At present,the design and debugging of system has been accomplished.The performance meets the expectant requirement.
