Paper Abstract

Higher-order quaternary signed-digit arithmetic using optical symbolic substitution is presented. This technique allows for multi-bit carry-free addition and borrow-free subtraction via a two-step symbolic substitution scheme and leads to a compact design by incorporating more information in fewer digits. Optical implementations based on a contentaddressable memory and on a multichannel correlator are identified.
