摘　　要：采用Altera公司FPGA提供的PCIe PHY IP和Synopsys公司提供的PCIe Core IP提出了一种PCIe总线接口的DMA控制器的实现方法,并搭建了4通道的PCIe传输系统。利用Synopsys VIP验证环境对系统进行了仿真验证,利用Altera Stratix V EX系列FPGA搭建平台进行了实际传输验证,验证了数据读写的正确性,在进行DMA读写事务操作时总线带宽峰值分别达到了1 547 MB/s和1 607 MB/s,能满足大部分实际应用中对数据传输的速率要求。A method to implement DMA controller of PCIe bus interface based on Altera FPGA PCIe PHY IP and Synopsys PCIe Core IP was proposed in this paper, and a 4-lane PCIe transmission system was builted. The correctness of reading and writing data was proved through the stimulation in Synopsys VIP environment and transfer verification in Altera Stratix V EX series FPGA platform. The bandwidth of DMA read and DMA write can achieve 1 547 MB/s and 1 607 MB/s respectively. The DMA controller can satisfy the demands of data transfer rates in most practical applications.
