Paper Abstract

Direct and indirect solutions to linear algebraic equations (LAEs) are considered with attention to the use of optical acousto-optic (AO) systolic array processors. Specific attention is given to error sources in one AO systolic processor. A case study of an LAE solution is conducted. The first error source model for an optical systolic array processor is advanced. Using this and digital computer modeling, a direct solution is found to be less sensitive to various optical system error sources than is an indirect solution. Acoustic attenuation is found to be the dominant error source in the AO systolic array processor considered. Related error source remarks on different bipolar data representation schemes and on optical versus digital solutions to a triangular system of equations are also advanced.
