A Novel Design of a 4 Bit Reversible ALU using Kogge-Stone Adder IJTSRD
Reversible circuits are one promising direction with applications in the field of low-power design or quantum computation. However, no real design flow for this new kind of circuits exists so far. Significant contributions have been made in the literature towards the design of reversible logic gate structures and arithmetic units, however, there are not many efforts directed towards the design of reversible ALUs. In this paper, a novel programmable reversible Kogge-Stone adder is presented and verified, and its implementation in the design ofa reversible Arithmetic Logic Unit is demonstrated. Then,reversible implementations of ripple-carry, Kogge-Stone carry look-ahead adders are analyzed and compared in terms of delay. The proposed design consists of the reversible Fred kin,Feynman, MG, HNG, PG and RKSC gates. The performance characteristics analysis is carried out in Xilinx environment.
