The key objective of today's circuit design is to increase the performance without the proportional increase in power consumption. In this regard, reversible logic has become an immensely promising technology in the field of low power computing and designing. On the other hand, data shifting and rotating are required in many operations such as arithmetic and logical operations, address decoding and...
Reversible shift registers are required to construct reversible memory circuits. This paper presents novel designs of reversible shift registers such as serial-in serial-out (SISO), serial-in parallel-out (SIPO), parallel-in serial-out (PISO), parallel-in parallel-out (PIPO) and universal shift registers. In order to show the efficiency, lower bounds of the proposed designs are shown in terms of number...
Reversible logic has become one of the most promising research areas in the past few decades and has found its applications in several technologies; such as low power CMOS, nanocomputing and optical computing. This paper presents improved and efficient reversible logic implementations for Binary Coded Decimal (BCD) adder as well as Carry Skip BCD adder. It has been shown that the modified designs...
