Application of Dual-Port RAM in data communication between DSP and microcontroller

Yi Kang

Abstract

In the multi-processors application system,the effective communication between two processors is the key element for the effective operation of the system.There are several communication methods between the two processors.There are several advantages by using Dual-Port RAM to realize communication,such as real-time capability,simple interface circuit and high volume data transmission etc.This paper introduces the architecture and function of dual-port RAM as well as the interface circuit and programming diagram.This interface circuit is also applicable to other kinds of multi-processors communication.
