摘　　要：提出了一种基于CPLD、通过电脑串口对多个DSP进行程序远程下载的系统。介绍了CPLD与上位机和底层DSP之间的接口电路,详细阐述了CPLD的内部原理图以及实现其内部各个功能模块的程序,给出了仿真的时序波形,并应用Visual Basic 6.0编写了上层界面,最终完成了多个DSP的程序远程受控下载。A long-distance programming loading system of multi- DSPs by serial communications based on CPLD is presented. The interface circuits between CPLD and PC, DSPs are introduced. Meanwhile the configuration fig inside CPLD and the program used to realize every module＇s function are expounded. The simulating waveform is shown and the man-machine interface is written by Visual Basic6.0. Ultimately it is realized that multi-DSPs can be long- distance programmed.

关 键 词：CPLD 串行加载 DSP 串口通信
