Design of DMA controller of PCIe bus interface based on FPGA

Abstract

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.
