DSP EMIF与FPGA双口RAM高速通信实现

Realization of high-speed communication between DSP and FPGA by EMIF dual-port RAM

现代电子技术的快速发展使得大量的数据需要处理与传输,为解决该问题,通过TMS320C6455的EMIF接口实现了DSP与FPGA之间的数据双向快速通信。FPGA通过EMIF接口将内部RAM中的数据传输给DSP进行处理,DSP将处理后的数据结果再通过EMIF接口传送到FPGA的片内接收模块双口RAM并进行存储。EMIF通道实现了对数据的传输,双口RAM完成了对数据的接收。实验结果表明,该设计方案能够实现数据的双向快速正确传输。

The rapid development of modern electronic technology requires the processing and transmission of plenty of da-ta. In order to solve this problem,TMS320C6455 EMIF interface was adopted to realized the rapid data intercommunication be-tween DSP and FPGA. FPGA transfers data in the internal RAM to DSP for processing through EMIF interface. DSP transmits the processed data through EMIF interface to dual-port RAM in FPGA to store. EMIF interface is used to achieve the data trans-mission,and dual-port RAM is used to realized the data reception. The experimental results show that the design scheme can realize data intercommunication quickly and correctly.
