OMAP-L138DSP与FPGA通信方案设计

Design on Communication between OMAP-L138 DSP and FPGA

针对双刀头高性能柔性材料切割数控系统,结合OMAP-L138+FPGA控制系统的数据传送需求以及平台资源,提出一种OMAP-L138的DSP通过EMIFA接口与FPGA的FIFO进行数据通信的设计方案,DSP将处理后的数据通过EMIFA接口传送到FPGA的异步缓存FIFO模块。FIFO在接收DSP发送的高速数据的同时,将缓存的数据输出。通过逻辑分析仪实验测试验证,该方案能够实现数据的正确通信。

A data communication design between OMAP-L138 DSP and FPGA FIFO is proposed with the data transfer requirement of OMAPL138 ＋ FPGA control system and the platform resources for High performance flexible materials pole head CNC cutting system. DSP transmits the processed data to FPGA via the asynchronous FIFO with EMIFA interface. And the FIFO receivers the high-speed data from DSP, while outputting data from the asynchronous FIFO. The design is verified to achieve the correct communication with the laboratory tests by logic analyzer.
