摘要
基于Xilinx FPGA Tandem PCIE模式配置程序加载原理分析,提出一种基于PCIE接口实现对PCIE板卡中FPGA程序的固化与更新方法,并进行软件开发验证.通过对应用程序、驱动程序以及FPGA内部软核的综合编程使用,该方法具有很高的灵活性,能够适应主机在远程端或者没有下载电缆在现场时的程序更新需求.
Abstract
Based on the analysis of the loading principle of the Xilinx FPGA Tandem PCIE mode configuration program,a solidification and update method of the FPGA program in the PCIE board is proposed based on the PCIE interface,and the software development is verified.With the com-prehensive programming use of applications,drivers,and soft cores inside the FPGA,the method is highly flexible and can adapt to program update needs when the host is at the remote end or in the field without a download cable.
