Abstract
Optically reconfigurable gate array (ORGAs) were developed to realize next-generation large-virtual gate count programmable VLSIs. An ORGA consists of an ORGA-VLSI, a holographic memory, and a laser array, which is used for addressing the holographic memory. Since many configuration contexts can be stored on a volume-type holographic memory, the corresponding number of lasers must be implemented on an ORGA. However, a laser array with numerous lasers is always expensive. Therefore, to accommodate numerous configuration contexts with fewer lasers, this paper presents a novel method using an interleaving read operation of a holographic memory for ORGAs. This method can provide an addressing capability of a billion configuration contexts along with a nanosecond-order high-speed configuration capability.
