Arithmetic Operations in Multi-Valued Logic

This paper presents arithmetic operations like addition, subtraction and multiplications in Modulo-4 arithmetic, and also addition, multiplication in Galois field, using multi-valued logic (MVL). Quaternary to binary and binary to quaternary converters are designed using down literal circuits. Negation in modular arithmetic is designed with only one gate. Logic design of each operation is achieved by reducing the terms using Karnaugh diagrams, keeping minimum number of gates and depth of net in to consideration. Quaternary multiplier circuit is proposed to achieve required optimization. Simulation result of each operation is shown separately using Hspice.Comment: 12 Pages, VLSICS Journal 201

Optical Quadruple Feynman Gate using SLM and Savart Plate

In recent years, Reversible logic is emerged as a promising computing paradigm with applications in low-power CMOS, quantum computing, optical computing and nanotechnology. The classical set of gates such as AND, OR, andEXOR are not reversible. However, optical computing technology the trinary and quadruple valued logic systems are the most important ones in the many valued logic system.In this paper, spatial light modulator (SLM) and Savart Plate based circuit has been proposed and described for realization of quadruple Fenyman Gate. It is optical in nature. SLM and Savart Plate can play a significant role in this field of ultra-fast all optical signalprocessing
