| Abstract(in English) | This paper presents a technique for ensuring reliable softcore processor implemented on SRAM-based Field Programmable Gate Arrays (FPGAs). Although FPGA is easy to be attacked by Single Event Upsets (SEUs), it can clear these errors due to its reconfigurability. In the case of combinational circuit, Triple Modular Redundancy (TMR) with the dynamic partial reconfiguration (DPR) assure its reliability. But these techniques don't assure reliability of the sequential circuit, because processing states are cleared by reconfiguration. So, we propose the synchronization technique after DPR using a interrupt process. Proposed system accomplish synchronization process only 8μs time overhead. |
