A 62.5 ns holographic reconfiguration of an optically differential reconfigurable gate array

To date, holographic configuration speeds have remained limited to 16 mus because of issues related to the architecture of optically reconfigurable gate array VLSIs (ORGA-VLSIs). Therefore, to improve the issue, optically differential reconfigurable gate array VLSIs (ODRGA-VLSIs) have been developed and have achieved zero-overhead and nanosecond optical reconfiguration. Moreover, the architecture of an ODRGA-VLSI has the advantage of accelerating the reconfiguration speed compared to that of other ORGAs. However, nanosecond holographic configurations and, in particular, rapid holographic reconfiguration exploiting the advantages of ODRGA-VLSIs have not been reported. Therefore, this paper presents results of the world´s fastest 62.5 ns holographic reconfiguration, exploiting advantages of the ODRGA-VLSI.
