Abstract: Owing to its unique technique of One-to-One Mapping between the inputs and the corresponding outputs, the ReversibleLogicGates are now finding profound as well as promising applications in emerging growing paradigms such as Quantum Computing, Quantum Dot Cellular Automata, Optical Computing, Digital Signal Processing, Low Power CMOS Design, Nanotechnology etc. The Reversible Logic has received great attention in the past recent years due to its ability in reducing the power dissipation, the major concern in digital designing. To generate a useful gate function the Reversible Gates require constant inputs, called Ancillary Inputs, and some additional unused outputs, called Garbage Outputs, in order to maintain the reversibility of the digital circuits. The paper presents a novel design of different Arithmetic and Logic Units such as Half Adder, Half Subtracter and 1-Bit Comparator, using the existing Reversible Gates and the proposed new Reversible CNOT, BJN, and Peres Gates.
Keywords: CNOT Gate, Peres Gate, BJN Gate.
