Design Of Information Processing Experimental Platform Based On DSP

The thesis introduced the requirements of Digital Signal Processing integrate system, and designed the Digital Signal Processing experiment system based on the new frame of DSP+CPLD. Modular design method is adopted in the system. The thesis designed the hardware in detail and tested including core module, controller module, memory module, matrix LCD module, voice process module, network control module, the bootloader module and PLD module, etc. About the software, the thesis introduced the algorithm and programmed the driver of FLASH memory, voice collection and LCD of voice control module; analyzed the data transmission mode between all the network protocols' of TCP/IP and PC to system, at the same time, analyzed leading and realization method of self-startup between SCM and DSP host port interface.
