Abstract :
Reversible circuits are one promising direction withapplications in the field of low-power design or quantumcomputation. However, no real design flow for this new kind ofcircuits exists so far. Significant contributions have been madein the literature towards the design of reversible logic gatestructures and arithmetic units, however, there are not manyefforts directed towards the design of reversible ALUs. In thispaper, a novel programmable reversible Kogge-Stone adder ispresented and verified, and its implementation in the design ofa reversible Arithmetic Logic Unit is demonstrated. Then,reversible implementations of ripple-carry, Kogge-Stone carrylook-ahead adders are analyzed and compared in terms ofdelay. The proposed design consists of the reversible Fredkin,Feynman, MG, HNG, PG and RKSC gates. The performancecharacteristics analysis is carried out in Xilinx environment.
