MSD Addition by Ternary Logic Optical Processor

Abstract

Ternary logic optical processor which is completed according to Decreased-Radix Design Principle (DRDP) can construct all dualistic ternary logic operators (add up to19683 kinds). There is no carry propagation of addition of Modified Signed Digit (MSD) representation and the computation only needs several dualistic ternary logical transformations. Thus, MSD addition completed by ternary logic optical processor can be fully-parallel and no carry. The principle, working steps and experiment results of this new method are discussed.
