DESIGN AND IMPLEMENTATION OF LOGIC OPERATIONS AND ALU WITH LOW DELAY PROFILE USING REVERSIBLE GATES

Basically, reversible logic gates are most commonly used in the applications of CMOS, SOC, VLSI and DSP to reduce the energy consumption. Mainly reversible logic gates use the one to one mapping technique. In this paper the design and implementation of logical operations and ALU using reversible gates are presented. Reversible gates generally use ancillary inputs to generate function of gate. In this system firstly logical and shifting operations are performed. The shifting operation performed in parallel form from right shift and left shift. In this paper design the ALU using DKG gate,DPG gate and TOFFOLI gtaes. By using these gates we achieved the effective results in terms of route delay, logic delay and total delay.
