PCI Express总线接口的DMA传输设计

摘要

在认真理解PCI Express协议及其应用技术的此基础上,使用FPGA实现PCI Express总线接口的DMA传输设计.本文主要从DMA发送模块、DMA接收模块和DMA状态控制模块三个部分对设计进行详细的介绍.最后,在基于Linux系统的PC机中实现PCI-E的驱动程序,使用BEEcube公司的miniBEE作为测试平台对设计进行检测并给出结果.%The DMA transfer design of PCI Express bus interface is realized by FPGA based on the in-depth understanding of PCI Express protocol and its application technology.This paper mainly introduces three parts of the design:DMA sending module,DMA receiving module and DMA state control module in detail.Finally,it realizes PCI-E driver in one PC based on Linux system,then uses miniBEE as a test platform of BEEcube Company to test the design and give the results.
