Optical Parallel Digital Computers – Pure Optical Parallel Array Logic System – Yoshiki

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 ...

Modular components for an optical array logic system.

On the basis of modularization of an optical parallel array logic system (OPALS), a new concept of an optical digital computer is considered. The OPALS is a parallel digital optical computing system using optical array logic capable of executing parallel neighborhood logical operations, or cellular logic. Modularizing functional elements in the OPALS, stability, reliability, and flexibility of ...

Parallel Logic Programming on Distributed Shared Memory System

This paper presents an implementation of a parallel logic programming system on a distributed shared memory(DSM) system. Firstly, we give a brie,f introduction of Andorra-I parallel logic programming system implemented on multiprocessors. Secondly, we ou'tline the concurrent programming environment provided by a distributed shared memory system-TreadMarks. Thirdly, we discuss the implementation...

Forward Position Kinematics of a Parallel Manipulator with New Architecture

The forward position kinematics (FPK) of a parallel manipulator with new architecture supposed to be used as a moving mechanism in a flight simulator project is discussed in this paper. The closed form solution for the FPK problem of the manipulator is first determined. It has, then, been shown that there are at most 24 solutions for FPK problem. This result has been verified by using other tec...
