基于EMIF模块的DM642与FPGA接口设计与实现

Design of the DM642 and FPGA interface based on EMIF

在分布式光纤传感系统中,通常采用FPGA对感应信号的采样、存储、处理和传输进行控制和管理。提出了一种新颖的DSP和FPGA相结合的方式,通过EMIF接口实现DM642对FPGA之间数据的传输。在Xilinx公司的器件上利用CHIPSCOPE对所编写的程序进行验证,实验结果表明:该方法能够通过EMIF接口很好地实现DM642和FPGA之间数据的读写操作的过程。

The sampling, storage, processing, transmission of actuated signal are controlled and managed by FPGA in the distributed fiber sensor system, the novelty way of Combining DSP with FPGA is presented in paper and the data is transmitted between DSP and FPGA by EMIF. The program is proved on Xilinx device by using the chipscope. The result indicates that the data can be transmitted between DM642 and FPGA based on EMIF interface
