摘　　要：提出了利用双口RAM实现DSP与红外干涉仪并行接口的设计方案,以使双方进行高速通信。介绍了双口RAM器件IDT7024的原理与使用规则,并针对设计方案给出了接口电路和软件流程。最后,针对二者交换数据的仲裁方式,提出了三种解决冲突争端的方法。A design method of dual-port RAM used in the interface between Digital Signal Processors （DSP） and an interferonleter is presented, in order to enable the DSP to communicate with the interferometer at a high speed. The principle and operation rule of the IDT7024 are described. According to the design, the interface circuit and flow chart are also presented. Finally, three methods are proposed to prcvcnt the conflict of two systems according to the arbitrated access to the data exchanged between both sides.
