Reversible - SAL Based Energy Efficient Design of CLA for DSP Application

A New Reversible with SAL logic generalization has been introduced for the very first time and it will emerge as a promising technology for ultra-low power VLSI design styles. The main principle of this reversible circuits are those circuits which will provide no information loss and computing process have all logic operations required that able to perform in a reversible manner thereby to reduce heat dissipation. This paper proposes a new circuit type adders design using reversible gates with SAL logic desire to higher densities and speed. As reversible logic very much useful for future research areas and it have variety of modern applications like optical computing, quantum computer, nanotechnology, DSP boards, FPGAs and energy saving embedded circuits. Thus, this paper also compares the implementation of proposed reversible-SAL design in terms of power consumption, delay, area, performance, energy dissipation and quantum cost. Proposed work provides significant improvement than other regular structures. The reversible – SAL based high speed adder circuits are designed and simulated using Tanner EDA tool under various process technology models.
