Optically Reconfigurable Gate Arrays (ORGAs), by exploiting the large storage capacity of holo- graphic memory, offer the possibility of providing a virtual gate count that is much larger than those of currently available VLSI circuits. Because circuits implemented on a gate array must often be changed using virtual circuits stored in a holographic mem- ory, rapid reconfiguration is necessary to reduce the reconfiguration overhead. A simple means to real- ize a short reconfiguration time in ORGAs is to im- plement a high-power laser array. However, such an array presents the disadvantages of high power con- sumption, large implementation space, high cost, and so on. Therefore, this paper presents an accelera- tion method to increase ORGAs' reconfiguration fre- quency without the necessity for any increase of laser power. This technique also includes optimization be- tween the number of reconfiguration contexts and the reconfiguration frequency. The description in this pa- per clarifies the advantages using simulation and ex- perimental results.
