A 62.5 ns holographic reconfiguration of an optically differential reconfigurable gate array
Mao Nakajima, Minoru Watanabe · 2007
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.
