Optical content-addressable parallel processor for high-speed database processing.

We extend the concept of optical content-addressable parallel processing [Appl. Opt. 31, 3241 (1992)] to a novel architecture designed specifically for the parallel and high-speed implementation of database operations called optical content-addressable parallel processor for relational database processing (OCAPPRP). An OCAPPRP combines a parallel model of computation, associative processing, wi...

Iterative processing on a hybrid optical parallel array logic system with a selectable coherent correlator.

A new version of an experimental system of an optoelectronic hybrid optical parallel array logic system is constructed. The experimental system is composed of a two-dimensional correlator with selectable holographic filters and parallel electronic circuits. The system can process images consisting of 3 × 3 pixels at a time. Several types of processing are achieved both without and with dynamic ...

Image Processing Applications using an Associative Processor Array

It was decided to implement the FFT on GLiTCH because it is both a useful routine for image processing and also very computationally demanding. When implemented on an array processor, the FFT serves as a good test of the mathematic and data movement capabilites of the machine. Given that GLiTCH is restricted on memory size, and is also only a pseudo-2D array, it was felt that the 2D FFT would s...

Massively Parallel Processing Using Optical Interconnections

This chapter discusses why and how optical communication technology might be used in future large scale parallel processing systems. Commercial systems currently being built can interconnect thousands of processors, and future systems may be even larger. Systems with thousands of processors are often called massively parallel systems. In these systems, the ability to eeciently communicate and s...
