Enhanced Radiation Tolerance of an Optically Reconfigurable Gate Array by Exploiting an Inversion/Non-inversion Implementation
To date, optically reconfigurable gate arrays (ORGAs) have been developed to realize highly dependable embedded systems. ORGAs present many beneficial capabilities beyond those of field programmable gate arrays (FPGAs): The most important is that an ORGA can be reconfigured using an error-included configuration context that has been damaged by high-energy charged particles. The radiation tolerance of an ORGA is extremely high. Moreover, if an inversion/ non-inversion implementation architecture is introduced to an ORGA, the configuration dependability of the ORGA for radiation can be increased drastically. This paper therefore presents a demonstration of the enhanced radiation tolerance of an optically reconfigurable gate array achieved by exploiting the inversion/ non-inversion implementation.
