Abstract

An opto-electronic shared content-addressable memory processor is used to perform parallel modified signed-digit (MSD) arithmetic operations. The MSD arithmetic operation (addition or subtraction of two N-bit numbers) is decomposed into a matrix-matrix multiplication followed by a combination of a threshold and logic operations.
