摘　　要：为了实现FPGA与TMS320DM642之间数据准确、高效、可靠的传输,给出FPGA的FIFO与TMS320DM642中EMIF(外部存储器接口)模块进行数据通信的一种设计方案。介绍EMIF与FIFO的结构特点,以及它们之间的硬件连接方式和软件实现方法。实验表明,该通信方案不但实现了数据的可靠、快速传输,而且具有结构灵活、调试方便等特点。In order to achieve accurate, efficient and reliable data transmission between the FPGA and TMS320DM642, we present a design solution for data communication between the modules of FIFO of FPGA and the EMIF （external memory interface） of TMS320DM642. The solution provides the structural characteristics of EMIF and FIFO, as well as their hardware connection and software implementation approaches. Experiments show that this communication solution achieves a reliable and fast data transmission, and also has the features of flexible structure and convenient debugging.
