Abstract

Demand is increasing daily for a robust field programmable gate array that is useful for operations performed in a radiation-rich space environment, such as those of spacecraft, space satellites, and space stations. Optically reconfigurable gate arrays (ORGAs) are under development as robust field programmable gate arrays. Their holographic memories can generate correct configuration contexts at any time, even if up to 20 % of the holographic memory data are damaged. However, up to now, a soft error effect for a laser array on ORGA devices has never been discussed. Therefore, this paper first presents a proposal of a method to find an unexpected configuration procedure caused by a laser array driver circuit facing a soft error on conventional ORGA architectures and to recover from such a procedure. Then this paper presents a proposal of a new robust laser array driver circuit that is applicable for any ORGA architecture, which can perfectly remove the unexpected configuration procedure itself.
