| Abstract: | In the paper,a new image processing system based on TMS320C30 is designed.Considering the applied algorithm and multiprocessor architecture,two valid communication methods have been proposed: (1) Interlocked Communication Method between the Host and Processing Unit;(2) Email-Box Communication Method between different processing units (PP1 and PP2).The two communication methods can ensure all commands be executed correctly among the Host and each Processing Unit (PP1 and PP2).The results show that the rate of error in communication has been reduced rapidly by using the two methods. |
