Single-Level Schematic Realization of Basic Operations of Modular Arithmetic in Unitary Codes

摘要

Some problems in the schematic realization of basic operations of modular arithmetic (operations of addition and multiplication modulo 5 and modulo 7) for the case of data representation in unitary codes are considered. Single-level logical schemes of modular adders and multipliers synthesized using EXCLUSIVE OR with a threshold are presented. These logical schemes are more efficient (in both complexity and depth) than the existing analogs.
