中文摘要: 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.
Abstract: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.
