基于Zynq平台PCIE高速数据接口的设计与实现
Design and Implementation for High Speed Data Transfer Interface of PCI Express Based on Zynq Platform
摘要
Abstract
In order to use the excellent transmission performance of peripheral component interconnect express (PCIE) interface to carry out high-speed communication between peripherals and the host effectively,a multi-channel and high-speed PCIE interface scheme is designed based on Zynq family chip of Xilinx.The DMA hardcore controller,device driver and application program are designed on the basis of PCI express 2.0 hardcore using the FPGA+ARM architecture of Zynq-7000 platform.Test results show that the transfer rate in our project almost can reach 3.3 Gbps in PCIE× 1 lane and single logical channel,which increases about 20％ compared with the traditional existing designs.Our scheme owns higher expansibility and wide application prospect,it is an important design reference for external equipment and PCIE interface.关键词
