Paper Abstract

An analog optical matrix-vector processor with 10-bit accuracy is described. The operating mode of the various components of the system and the system architecture are reviewed. The system is capable of handling bipolar and complex-valued data with no loss in throughput. Various applications of this architecture and initial laboratory data and simulation results are provided. Applications addressed include: finite impulse response filters, two high/low accuracy algorithms and systems for solving linear algebraic equations, a correlation cancellation loop processor and new algorithms and architectures for the discrete and continuous steepest descent algorithms and solutions, plus preconditioning algorithms and associated techniques for these systems, and finally constrained LAE solutions for reduced accuracy processors (using ridge regression techniques).
