Title
Triple module redundancy scheme on an optically reconfigure gate array
Abstract
Demand for programmable devices for space applications is increasing day by day to support hardware repair functions, hardware update functions, and hardware 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 configuration data that are damaged by high-energy charged particles in a radiation-rich space environment The amount of configuration data damage that can be sustained by ORGAs is greater than that by FPGAs with error checking and correction (ECC). An ORGA is therefore extremely robust in terms of its configuration data. Moreover, the ORGA's programmable gate array is reconfigurable at nanosecond order, with more than 100 reconfiguration contexts. For that reason, high-speed repair and update are possible. However, an ORGA's programmable gate array itself is never as robust against space radiation as that of an application-specific integrated circuit (ASIC) because the gate array's programmable architecture is identical to that of an FPGA. Therefore, this paper presents a proposal of a triple module redundancy scheme on an ORGA to achieve the same robust ability as that of ASICs.
