| Abstract: | A design based on the Xilinx Virtex-6 FPGA embedded PCI Express Core is presented, which im- plement the DMA read and write initiatively launched by the PCI Express board for high-speed data transfer between PC and PCI Express board. The design has been debugged and verified on the Xilinx evaluation board ML605. With a DMA write memory speed up to 1 520 MB/s, the design can meet the requirements of high-speed storage system. |
