When multiprocessor systems is working,in order to realize the rapid and effective communication,this paper introduced using multiple processors shared memory scheme.IDT7134 dual-port RAM is selected as sharing memory.According to the plan,this paper gave the interface circuit of hardware and software design.In the interface circuit design,it focused on the IDT7134 and CPU connection.In software design,this paper focused on how to handle the address contention when the both ports of the RAM have accessed the same location at the same time.Through setting up some software indications to avoid conflicts,it effectively realized data transmission with high speed.This program has been approved by theory and practice that it is feasible and effective.
