摘要
PCI Express技术已成为PC桌面电脑和图形设备的标准互联总线,占据着主要市场。它作为第三代I/O总线互联技术开始取代PCI,PCI-X技术,成为最主要的高速互联技术,其已应用在服务器、移动设备、工作站、网络设备、通信设备、工业控制设备、图形设备等领域。通过分析PCI Express协议原理和Virtex5 Lxt PCIE Endpoint block硬核模块结构功能,设计基于Virtex5 lx50t硬件板卡,实现了PCI Express的数据传输。
Dominating the desktop PC motherboard and graphics markets, the PCI Express （PCIe） interconnect is poised to supplant PCI and PCI- X as the dominant high-bandwidth interconnect for the server, enterprise, mobile, workstation, networking, communications, industrial control and medical equipment markets. The PCI- Express specification is analysed,and the structure and function of Virtex5 Lxt PCIE Endpoint block hard core are tested in this article. A hardware card based on Virtex5 Lxt chip is designed,the data transform of PCI - Express bus is implemented.
