Abstract
Reconfiguration applications based on reconfigurable devices present
new computational paradigms since, by increasing the reconfiguration frequency
of reconfigurable devices, their activity and performance can be improved
dramatically. Recently, Optically Reconfigurable Gate Arrays (ORGAs) with
a holographic memory were developed. They realize rapid reconfigurations and
numerous reconfiguration contexts. Furthermore, Optically Differential Reconfigurable
Gate Arrays (ODRGAs) have been developed to accelerate optical reconfigurations
of conventional ORGAs. However, fast configuration experiments under multiple
contexts exploiting the ODRGA architecture have never been reported. Therefore,
this paper presents a four-context ODRGA system and experimental results demonstrating
its fast reconfiguration. The advantage of the ODRGA architecture is discussed
based on those results.
