Design of non-restoring binary array divider in quantum-dot cellular automata

Quantum-dot cellular automata (QCA), a promising candidate nanotechnology for the next generation computers, has attracted the interest of researchers all over the world since 1993. The divider is a major component of arithmetic logic unit, which has a remarkable impact on the performance of the central processing unit. The widely used algorithm in the divider is the non-restoring division, but there is no work which has reported the implementation of non-restoring dividers based on QCA. Presented is the design of a non-restoring binary array divider in QCA and its validity is verified using QCADesigner software. The proposed non-restoring divider has the advantage of time-saving and is easy to control when compared with the existing restoring dividers.
