The development process of SRAM-based FPGA is various,and it is widely applied to astronautics. The SRAM FPGA are sensitive to single event upset ( SEU) which might result in information loss or functional interruption. The adverse effects caused by SEU can be effectively controlled by Triple Modular Redundancy ( TMR) and scrubbing. The TMR and scrubbing are discussed in detail. The solution of self-hosting configuration management and TMR is proposed. The efficient use of resources is improved based on self-hosting configuration management of FPGA,and the fault injection test result shows that this solution is feasible.
