摘　　要：数字信号处理器(DSP)作为嵌入式系统的核心器件被广泛应用于各个领域,急需专用的DSP辅助调试工具,在此介绍了一种基于CompactPCI接口的DSP总线监控仪的设计方法。应用FPGA构建DSP数据采集和控制系统,将数据通过高速LVDS接口传到上位机。同时,还简述了上位机通信接口卡WDM驱动程序的中断部分编制方法,最后简单的介绍了从应用程序中C语言语句查找对应机器地址的方法。以TI公司的TMS320C50为监控对象的设计实例,阐明了设计方法的实际应用。该设计方法稳定可靠,可以扩展应用于TI公司其他系列的DSP。Digital signal processor （DSP） as the core of embedded system devices are widely used in various fields, a dedicated DSP-assisted debug tools is in urgent need. A DSP based on the CompactPCI bus interface design method of monitor is introduced, which can implement real-time supervision on DSP bus. the system can transfer data to the master pc by high-speed lvds. Meanwhile , this paper give some words about how to program the WDM Driver＇ s interrupt handle for this card. Final some introduce was given about finding machine address from the program. The design method is stable and reliable and can be extended to other series of TI＇s DSP.
