Tehniat Banu, Manjunath R Kounte, Syeda Taranum · 2013
In recent years, there is a remarkable paradigm shift in computation efficiency due to information lossless computation performed by the reversible logic. The reversible logic means performing computation in such a way that using the output the input can be constructed and the erasure of intermediate data and power dissipation is eliminated. The reversible logic has been found advantages in the areas such as quantum computing, low power CMOS, Nano-Technology and optical computing. The classical counter developed with the gates such as NAND and NOR gate are not reversible. In this paper we will introduce few reversible gates such as Feynman gate, Sayem gate and using these gates we will construct a 4-bit Reversible asynchronous Up/Down counter and the corresponding output of the reversible counter obtained using tanner tool v.13 with 250nm technology is verified.
