High-speed optically reconfigurable gate array exploiting a MEMS and a laser array

Optically reconfigurable gate arrays (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. Although 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 research has demonstrated a microelectromechanical system (MEMS) interleaving method for a holographic memory of optically reconfigurable gate arrays. This method can provide an addressing capability of a billion configuration contexts along with a nanosecond-order high-speed configuration capability.
