A 100-context optically reconfigurable gate array

To date, optically reconfigurable gate arrays (ORGAs) have been developed to realize large virtual gates and to increase gate array performance by combining a holographic memory with a programmable gate array. Among such studies, a 16-context ORGA architecture with nanosecond-order reconfiguration capability has already been demonstrated. However, its reconfiguration contexts are too few to execute large real-time operations. This paper therefore presents a proposal of a more advanced 100-context ORGA architecture in addition to related experimental results.
