Abstract

An optically reconfigurable gate array (ORGA) system, which consists of an ORGA very large scale integration (VLSI), an easily rewritable liquid crystal holographic memory recording four configuration contexts, and a laser array, is proposed. Circuits on a gate array of the ORGA-VLSI can be programmed rapidly by exploiting large parallel connections between a holographic memory and a gate array VLSI; that programming can be executed even as it is being programmed. Consequently, the gate array can be switched from a certain circuit to another circuit instantaneously. We present a demonstration of the ORGA system and experimental results.
