Optically reconfigurable gate arrays (ORGAs), which consist of a gate array VLSI, a holographic memory, and a laser diode array, are a type of programmable gate array that can achieve rapid reconfiguration for numerous reconfiguration contexts. The gate array of an ORGA is optically reconfigured using diffraction patterns from a holographic memory that is addressed by a laser diode array. It is noteworthy that ORGA-VLSIs that can be reconfigured in less than 10 ns without any overhead have already been fabricated. However, up to now, a multi -holographic reconfiguration system that is suitable for such fast-reconfigurable ORGA-VLSIs without any overhead has never been developed. As the first step toward such realization, a multi-context component is demonstrated experimentally using a liquid crystal spatial light modulator and a pulse laser. This paper describes experimental results and plans for future work.
