Abstract

Recently, to realize autonomous functions resembling those of humans on space systems, higher-performance embedded systems than those of current space systems are necessary for use in long-distance space missions. Currently, a parallel-operation-oriented optically reconfigurable gate array (ORGA) has been under development. The ORGA can support a nanosecond-order high-speed reconfiguration and high-density implementation of parallel operations. The parallel-operation-oriented ORGA has many programmable gate array layers, which share a common configuration context and increase the number of implementable parallel operations. Therefore, a parallel-operation-oriented ORGA is suitable for hardware acceleration of a software operation on a processor. However, in a space environment, triple modular redundancy (TMR) must be used. Single common configuration memory becomes a weak point for radiation in terms of redundancy. Therefore, we propose a TMR implementation method that is suitable for the parallel-operation-oriented ORGA.
