✦ Synopsis

A symbolic substitution (SS) based optical numeric processor using quaternary signed-digit (QSD) number representations is proposed. Also, we propose new joint spatial encodings for the QSD numbers that reduce the SS computation rules involved in the processor. Optoelectronic implementation of the proposed QSD adder is feasible. The proposed adder is more compact than recently reported QSD counterparts.
