摘　　要：根据数字失超探测器数据采集系统的应用需求,设计实现了现场可编程逻辑阵列(FPGA)和数字信号处理(DSP,TMS320C40)之间基于直接存储器访问(DMA)方式的通讯,介绍了两种平台间数据通讯的特点及通讯接口的硬件设计,并对DMA通讯机制、FPGA逻辑编程及DSP通讯控制程序等的实现进行了详细描述。该设计已通过实验平台的测试,并应用于数字探测器数据采集及处理系统中。According to the application requirements of Digital Quench Detection Device data acquisition and processing system, the communication with the Direct Memory Access （DMA） method under the Field Program- mable Logic Array （FPGA） and Digital Signal Processing （DSP） platforms was designed and implemented. Base on the platforms, the characteristics of data communication, the hardware design of communication inter- face, the DMA communication mechanism and the soft design of FPGA logic programming and DSP communica- tion control program were given detailed discussion in the paper. The research has been proved and used to the Digital Quench Detection data acquisition and processing system.
