Abstract

The basic algebraic properties of Parity Function and the relevant relations are summarized. Two basic Parity Function Modules, PFM2 and PFM3, respectively for two and three variables, are proposed as the building blocks for optical realization of general multi-level parity functions. The performance and the number of key active components, and the levels of logic and/or functional operations required for each of the proposed configurations are given. A unique dual purpose Combined Full Adder-Subtractor, optically cascadable for simultaneous parallel addition and subtraction of multi-bits is presented as an example of simple application involving Parity Functions.
