Abstract
A symbolic substitution (SS) based optical numeric processor using quaterna ry signed-digit (QSD) number representations is proposed. Also, we propose new joint spatial encodings for the QSD numbers that reduce the SS computat ion rules involved in the processor. Optoelectronic implementation of the p roposed QSD adder is feasible. The proposed adder is more compact than rece ntly reported QSD counterparts, (C) 1999 Elsevier Science Ltd. All rights r eserved.
