Reversibility is among the rapidly evolving areas of system design, where the design has ideally zero power dissipation. Considerable research and designs have been developed in this field and the recent designs of MACs (Multiplier and Accumulators) and memory elements in reversible logic are still a budding field of research. Reversible logic is a very promising choice for quantum computational systems, DNA computation and other Low Power digital system designs. Here, we propose three novel reversible Non-Linear Shift Register (NLFSR) designs. The proposed designs are implemented and compared in terms of area and power with a conventional non-reversible NLFSR design using the Synopsys Design Compiler Tool and ModelSIM Quartus 6.5. The proposed novel designs give a considerable reduction in switching power, when compared with the conventional design.
