| Abstract: | 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. |
