Design of Barrel Shifter Based on Quantum-Dot Cellular Automata
Nanotechnologies are widely seen as having huge potential to bring benefits to many areas of research and
application. Quantum-dot cellular automata (QCA) is one of the future nanotechnology that can replace currently CMOS
technology. Multiplication is mostly studied implementation in computing. A typical implementation is a process that
repeats addition method till to get the result. In arithmetic and logic operations barrel shifter is used to shift a desired number
of bits in a desired direction. Therefore, it is important component for the design of modern microprocessors. In this paper
we proposed barrel shifter design based on QCA technology.
