Paper Abstract

In the 1950s, digital designers noted that residue number systems offer the attractive feature of carry-free addition, subtraction, and multiplication. This interest waned, in part because residue number systems possess a multi-state character; flip flops and other binary state devices lend themselves more naturally to binary arithmetic than to multi-state arithmetic. Optics enjoys the requisite multi-state capability: lenses can resolve many discrete positions, gratings can resolve many discrete frequencies, and so forth. This fact has motivated efforts to create a residue based optical processor, which would combine the parallel, speed of light throughput of optics with processing accuracies possible only to digital systems. Our program has included the identification of appropriate roles for residue processors, the investigation of I/O techniques, such as analog to residue and residue to radix conversion, and the study of optical implementations of residue arithmetic.
