Abstract

To date, optically reconfigurable gate arrays (ORGAs) consisting of a holographic memory, a laser array, and an optically reconfigurable gate array VLSI have been developed to realize fast reconfiguration and numerous reconfiguration contexts. Numerous configuration contexts can be stored on a holographic memory and can be programmed dynamically onto a gate array in a nanosecond-order period. Such high-speed dynamic reconfiguration enables a large virtual gate over a physical gate, for example a 1 Tera-gate VLSI. However, in addition to the advantages, the ORGA architecture allows high-speed optical Fourier transformation by addition of a programmable Fresnel lens. This paper presents a proposal of a new ORGA architecture to support Fourier transformation and results of its demonstration.
