Demand for programmable devicesfor space apIs Increasing day by day to support hardware repair functions, hardware update functionshardware acceleration for space systems. To meet those needs, one candidate Is an optically reconfigurable gate array (ORGA)because the ORGA can be reconfigured with invalid coniiguration data that are damaged by high-energy charged particles Ina radiation-rich space environment. The amount of coniiguration data damage that can be sustained by ORGAs is greater thanthat by FPGAs with error checking and correction (ECC). An ORGA Is therefore extremely robust in terms of its coniigurationdata. Moreover, the ORGANS programmable gate array Is reconfigurable at nanosecond order, with more than 100 reconfigurationcontexts. For that reasonhigh-speed repair and updateare possible. However, an ORGA programmable gate array itselfis never as robust against space radiation as that of an application-speciiic Integrated circuit (ASIC) because the gatearray"s programmable architecture Is identical to that of an FPGA. Therefore, this paper presents a proposal of a triplemodule redundancy scheme on an ORGA to achieve the same robust ability as that of ASICs.
