一种基于FPGA的在线程序升级方案

Scheme of a in-system program updating based on FPGA

介绍了一种基于XILINX FPGA的在线程序升级方案,该方案不需要额外增加器件,在不改变硬件状态的前提下,实现产品的软件功能升级。由于对配置芯片(PROM)的所有操作均由FPGA的内部逻辑实现,故此方案具有良好的移植性和扩展性。

A in-system programming updating scheme based on XILINX FPGA is proposed. The product software functions can be updated with no destruction of hardware status and no need for adding extra devices.As all of the operations on PROM are imple- mented by means of FPGA＇s logic resources,the scheme has good portability and scalability.
