摘　　要：设计了一种大规模使用FPGA作为主要器件构建分布式系统的固件升级方案,并涵盖了软硬件设计。为了降低系统调试和维护期间固件升级的复杂程度,提高调试及固件升级效率,设计了一种解决方案。采用Xilinx FPGA的SelectMap配置方式,使用DSP作为主处理器为FPGA提供加载驱动,万兆以太网及万兆以太网交换机为系统提供组网能力,使整个系统具备使用PC上位机进行固件一键升级的能力。该方案可在相控阵雷达等系统上进行应用。A firmware upgrade scheme using FPGA as the main device to build the distributed system on a large scale is designed,and covers the design of software and hardware.In order to reduce the complexity of firmware upgrade during system debugging and maintenance and improve the efficiency of debugging and firmware upgrade,a solution is designed.The SelectMap configuration mode of Xilinx FPGA is adopted,DSP is used as the main processor to provide loading driver for FPGA,and 10 Gigabit Ethernet and 10 Gigabit Ethernet switch are used to provide networking capability for the system.The whole system has the ability to use PC host computer to upgrade firmware with one click,which can be applied in systems such as phased array radar.
