摘　　要：传统的FPGA程序更新的方式是使用开发工具通过JTAG方式将FPGA程序固化至存储器件Nor Flash中,当某一复杂系统内需要更新多块FPGA时,JTAG方式由于同时只能更新一块FPGA,耗费时间长,并且还必须连接线缆,无法实现远程更新。因此,提出了一种FPGA在线更新程序的实现方案,该方案可以实现系统内的多块FPGA程序更新,最大化更新速度的同时,可通过网络实现远程更新,便于调试及远程升级。Traditional way of FPGA configuration file update is using development tools to write FPGA target code to storage devices such as Nor Flash through the JTAG way.However,when the system becomes complicated with multiple FPGA,it takes a long time to update all the FPGA due to the limitation that the JTAG way can only update FPGA once a time.Therefore this paper proposes a FPGA online updating method,which can update multiple FPGA programs at the same time,greatly shorten the update time and reduce the cost of the system.
