基于Virtex-5的PCI-Express总线接口设计和实现

Design and Implementation of an PCI-Express Bus Interface Based on Virtex-5

本文描述了第三代通用I/O总线PCI-Express产生的背景,分析了PCI-Express总线的主要特点及体系结构。同时描述了在Xilinx公司的Virtex5系列的XC5VLX50T FPGA芯片上实现PCI-Express x4总线的设计并进行的相应传输速率的测试。

This paper describes the background of the third-generation I/0 bus, PCI-Express, analyses the main features and architecture of PCI-Express Bus. At the same time, the paper describes the design of a PCI-Express x4 bus based on XC5VLX50T FPGA chip which belongs to Virtex-5 series from Xilinx, and the testing of the transmission rate.
