| Abstract(in English) | SRAM-based FPGAs are susceptible to SEU which is induced by high energy particles or radiation. An SEU can corrupt the system output and can alter the function of the FPGA. This paper focuses on FPGA for real time applications and proposes a reactive rejuvenation scheme on a dual-FPGA architecture to handle SEUs. Duplication check is utilized to detect errors. Rollback and re-computation will be attempted when the error is detected. If the error remains, the rejuvenation will be triggered. After the rejuvenation the FPGA is assured to be fault-free. The proposed architecture consists of two identical FPGAs. Even if one has to undergo a rejuvenation process, the other is available to operate the system. This ensures the real time computing constraint of the application. The proposed architecture is expected to improve the reliability and the resilience of the system. Key words Single event upset, FPGA fault tolerance, rejuvenation, real time application. |
