Abstract:PCI Express is a new bus and interface standard.It supports high speed data transmission,point to point connection and hot plugging.This paper introduces the development and structure of PCI Express bus firstly.In the process of acquisition device design,the solution is chosen by using Xilinx FPGA and PHY chips,then the hardware system design is realized in details.Describing the physical layer,link layer and transaction layer of PCI Express in Xilinx Pipe Core.And then the simple driver program development is given by WinDriver.Data acquisition device based on PCI Express bus can develop the performance and replace the acquisition device based on other bus.
Keywords:PCI Express  PHY Pipe Core  WinDriver
