To date, optically reconfigurable gate arrays (ORGAs) have been developed to realize large virtual gates and to increase gate array performance by combining a holographic memory with a programmable gate array. Among such studies, a 16-context ORGA architecture with nanosecond-order reconfiguration capability has already been demonstrated. However, its reconfiguration contexts are too few to execute...
Fast reconfiguration and numerous reconfiguration contexts are two important features of dynamically reconfigurable devices. However, realizing both is difficult in current dynamically reconfigurable devices. Therefore, optically reconfigurable gate arrays (ORGAs) have been under development to solve this problem. Actually, ORGAs can realize a large virtual gate count over current VLSIs by combining...
Reconfiguration applications based on reconfigurable devices present new computational paradigms because increasing the reconfiguration frequency of such devices can enhance their activity and performance dramatically. Recently, optically reconfigurable gate arrays (ORGAs) with a holographic memory were developed, achieving important new advances in the areas of rapid reconfiguration and numerous...
Demand for fast dynamic reconfiguration has increased since dynamic reconfiguration can accelerate the performance of processors. Dynamic reconfiguration has two important prerequisites: fast reconfiguration and numerous reconfiguration contexts. Unfortunately, fast reconfigurations and numerous contexts share a tradeoff relation on current VLSIs. Therefore, optically reconfigurable gate arrays were...
Demand for fast dynamic reconfiguration has increased since dynamic reconfiguration can accelerate the performance of implementation circuits on a programmable device. Such dynamic reconfiguration necessitates two important features: fast reconfiguration and numerous contexts. However, because fast reconfiguration and numerous contexts share a tradeoff relation on current VLSIs, optically reconfigurable...
Optically differential reconfigurable gate arrays (ODRGAs) have been developed to achieve rapid reconfiguration and numerous reconfiguration contexts. Although fast reconfiguration experiments of a four-context ODRGA have been presented in earlier reports, the number of configuration contexts was insufficient for dynamic reconfiguration applications. Therefore, we have developed a more advanced nine-context...
