摘　　要：多种应用环境中不允许使用JTAG下载器升级可编程器件的程序,要求通过设备对外的通信接口实现可编程器件的在线升级,对于XILINX公司的FPGA芯片及其配置芯片,提出了一种基于USB接口的程序在线升级方法。该USB2.0接口是扩展在FPGA上用于与上位机进行通讯的接口,通过与上位机软件配合,对FPGA配置芯片进行擦除和编程烧写,实现FPGA程序的在线升级。本文给出了该方法的升级原理和方法。JTAG downloader is not allowed to upgrade the programmable devices in various application. The external communication interface of the device is required to upgrade the programmable devices. For the FPGA chip and its Flash PROM chips of XILINX Company,an online upgrade program method based on USB interface is proposed. The USB2.0 interface is an interface which extends the FPGA and communicates with the computer. The Flash PROM chips can be erased and programmed with the software,and then the online upgrade of the FPGA can be achieved. The upgrading principle is proposed in this paper.
