基于FPGA的远程快速在线升级技术研究

Research into a Rapid Remote Online Upgrade Technology Based on FPGA

现场可编程门阵列(FPGA)在电子对抗领域如多通道数字接收机、波束合成阵列中大量应用,使用现有的JTAG调试器对其进行升级非常耗费时间。基于可执行文件对FPGA进行Multiboot配置,将FLASH配置区域进行自定义分区规划,通过千兆以太网对多块FPGA完成远程在线升级。该方法简化了配置链路,降低了配置复杂度,提升了配置速度;使用网线远程完成任务,省去了分批多次配置时需在多块板卡上进行拔插的复杂流程,克服了已列装设备在地理位置和结构上的诸多不便;具有校验回退机制,保证了配置安全。

Field programmable gate array(FPGA)is widely used in the field of electronic countermeasures such as multi-channel digital receiver and beam synthesis array.It is very time-consuming to upgrade FPGA by the existing JTAG debugger.Multiboot configuration of FPGA is performed based on executable files,and customized partition planning of FLASH configuration area is carried out,then the remote online upgrade of multiple FPGAs over gigabit Ethernet is finished.This method simplifies the configuration link,reduces the configuration complexity,and improves the configuration speed,completes tasks remotely by using network cables,which eliminates the complicated process of pulling and plugging of multi-board for multiple batches of configuration,and overcomes many inconveniences in the geographical location and structure of the installed equipment.The verification rollback mechanism ensures the configuration security.
