摘　　要：在多处理器的应用系统中,处理器之间的有效通信是系统能否协同工作的关键。多处理器之间的通信方法有很多种,以双口RAM作为共享存储器来实现2个处理器之间的通信具有实时性好、接口电路简单、数据传输量大等优点。文中介绍了双口RAM内部结构与功能,以及用它来实现DSP与单片机之间通信的接口电路与通信流程,此接口电路同样适合其他类型的多处理器间的通信。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.
