基于Xilinx PCI Express Core的高速DMA读写设计

High-speed DMA Read and Write Design Based on Xilinx PCI Express Core

本设计在基于Xilinx Virtex-6 FPGA内嵌PCI Express Core的基础上,实现了由PCI Express板卡主动发起的DMA读写,可完成PC和PCI Express板卡之间数据的高速传输。该设计已经在Xilinx评估板ML605上完成调试验证,DMA写内存速度稳定可达1 520 MB/s,满足了高速存储系统的要求。

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.
