Abstract

Various scheme and technical implementations of a vector- matrix multiplier for neuronetworks design are considered. Variants of the VMM laboratory model on the basis of the traditional optics and standard optoelectronic components are worked out. Input and output vectors are realized accordingly as radiation source and photodetector matrices; weights set with the help of a projector LCD. Possibility of an integrated optical VMM implementation as a monolithic circuit is considered; peculiarity of a planar circuit working is noted. The results of circuit elements calculations and complete VMM circuit arranging with a control block diagram are presented. This neurochip is made on the GaAs substrate by means of the traditional semiconductor technology (0.35 mkm) and takes 40 X 10 mm² area.
