This paper proposes a method of superimposing acceleration and optimizing the optical reconfiguration speed while requiring no increase of laser power. Using this technique, the optical reconfiguration speed is increased by superimposing multiple configuration contexts. Simultaneously, optimization of the number of configuration contexts and reconfiguration speed is possible. A full four-context optically reconfigurable gate array system consisting of an optically reconfigurable gate array VLSI, an easily rewritable liquid crystal holographic memory, and four vertical-cavity surface-emitting lasers was constructed to demonstrate this method. This paper clarifies the method's benefits using experimental results obtained from the demonstration system.
