Design of arithmetic logic unit in QCA

Abstract

In this chapter, we examined the reversible arithmetic logic unit (ALU) and its implementation in QCA framework. ALU is one of the fundamental components as it defines the performance of any processing systems. This chapter is structured in four sections. First section discusses different ALU structures in QCA. In Sect. 7.2, we analyze and validate one of the reversible ALU designs in QCA framework. Section 7.3 inspects the complexity of different reversible and non-reversible ALU structures with comparative analysis. Section 7.4 presents the summary of the chapter. © Springer Nature Singapore Pte Ltd 2020.
