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.
提出了利用光学符号替换实现高阶修正符号位三进制算术运算的技术。该方法通过采用两步符号替换方案提供快速多位计算。由于用较少的位数表示了更多的信息，该技术导致了紧凑的设计。还提出了基于内容可寻址存储器和基于联合变换相关器的该技术的光学实现。
