This study presents efficient algorithms for performing multiply-by-3 (3N) and divide-by-3 (N/3) operations with the additions and subtractions, respectively. No multiplications and divisions are needed. Full adder (FA) and full subtractor (FS) can be implemented to realize the N3 and N/3 operations, respectively. For fast hardware implementation, this paper introduces two basic cells UCA and U...

In recent years, Quantum Electronics and Reversible Logic have emerged as a major area of research having applications in low power CMOS circuits, cryptography, optical computing and nanotechnology. The fact that classical logic gates such as AND, OR, XOR etc., barring the NOT gate, cannot predict the input given the output and hence generate heat due to information loss, has given rise to the ...

In this paper, the possibility of using a silicon waveguide based microring resonator as a nonlinear all-optical switch is described under low power operation through a two-photon absorption effect. All-optical multiplexer/demultiplexer scheme based on two cascaded microring resonators has been proposed and described. The proposed circuits require smaller number of ring resonators and a single ...
