Dsp Experimental Platform For The Development And Design

The theories and techniques of DSP are basic engineering theories and core techniques of electronics technique and IT field nowadays. Actually,the technique of DSP has already been deep into all kinds of applied industry technique, it has already become the common foundation of various new technical at the beginning of 21 centuries. Therefore,it has very important significance in applying DSP techniques into teaching practice. The system takes the TM320VC5402 chip of the TI company as the core to set up the minimum work system,thus sets up an open experimental platform,make it easy to master the chip's basic function and application.This paper is composed of four parts The first part introduces the DSP chip's characteristics,function index,internal structure,the software development tool etc.. and the minimum system which is set up with the 5402 as the core chip. The second part introduce the extend circuit of A/D and D/A conversion base on the minimum system. The third part introduces the signal generator. The forth part introduces the serial to parallel and parallel to serial converse circuit.The research of this topic,make the learner not only carry on the regular DSP experiment to grasp the chip's basic function and program method but also extend the hardware platform according to the user's different needs. Thus make the learner have a good foundation and the teaching have more practical meaning, more gradually, more systematize and more easy to master. In actual application, the system is easy to fix and upgrade quickly.
