双口RAM在FPGA与DSP通信中的运用

Application of True Dual Port RAM in Communication Between FPGA and DSP

设计实现了一种基于双口RAM的FPGA与DSP通信方式,使用EMIF接口在FPGA与DSP之间进行双向数据传输,通过RAM的A端口进行FPGA读写操作,B端口进行DSP的读写操作,且FPGA写数据与DSP写数据存放在不同的RAM地址空间。实验结果表明,该方法简单灵活,能够在FPGA与DSP之间进行可靠的数据传输。

This paper describes and implementes a communication method between FPGA and DSP based on True Dual Port RAM,which used EMIF interface to transmit data,adopted port A of RAM for FPGA reading and writing operation,and port B of RAM for DSP operation,and stored data in different RAM space while FPGA and DSP writing.The experimental results show that the method is simple and flexible and has high reliability of data transmitting between FPGA and DSP.
