Abstract: A firmware upgrade scheme is designed to build the distributed system using FPGA as the main device on a large scale, 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 asphased array radar.

Key words: FPGA, SelectMap, firmware upgrade, 10 Gigabit Ethernet
