Abstract
Cellular arrays have been the topic of interest in computer arithmetic and architecture for the last four decades. In this letter, an overall quantum-dot cellular automata (QCA) design for a generalized pipeline cellular array is presented. QCA is one of the promising emerging nanotechnologies that are being considered as possible alternatives to complementary metal-oxide semiconductor technology due to the physical limitations of CMOS. The QCA designs for arithmetic cell and control cell used in the pipeline array are discussed in detail. The equivalent majority logic networks to these cells are generated using the best existing majority logic synthesis method in order to obtain the optimal majority networks which require fewer QCA cells and clock zones compared to other synthesis methods. The proposed array can perform all the basic arithmetic operations such as squaring, square rooting, multiplication, division, etc., which could be quite valuable in considering future large-scale QCA designs.
