Optical processing based on conditional higher-order trinary modified signed-digit symbolic substitution.
Techniques for higher-order modified signed-digit trinary arithmetic by using optical symbolic substitution are presented. This method provides fast multibit computation by adopting a two-step symbolicsubstitution scheme. Since more information is represented in fewer digits, this technique leads to a compact design. A content-addressable memory-based and a joint transform correlator-based optical implemention for the proposed technique are also presented.
