Purpose-In this research work,brief quantum-dot cellular automata(QCA)concepts are discussed through arithmetic and logic *** work is most useful for nanoelectronic applications,VLSI industry mainly depends on this type of fault-tolerant QCA based arithmetic logic unit(ALU)*** ALU design is mainly depending on set instructions and rules;these are maintained through low-power ultra-functional tricks only possible with QCA-based reversible arithmetic and logic unit for *** main objective of this investigation is to design an ultra-low power and ultra-high-speed ALU design with QCA *** following QCA method has been implemented through reversible ***/methodology/approach-QCA logic is the main and critical condition for realizing NANO-scale design that delivers considerably fast integrate module,effective performable computation and is less energy efficiency at the nano-scale(QCA).Processors need an ALU in order to process and calculate *** ALU in QCA technology utilizing reverse logic is the primary objective of this *** are now two sections,*** ALU(RAU),logical(LAU)and arithmetical(RAU).Findings-A reversible 231 multiplexer based on the Fredkin gate(FRG)was developed to allow users to choose between arithmetic and logical *** full adders are also implemented to improve arithmetic operations’*** ALU is built using reversible logic gates that are ***/value-In contrast to earlier research,the suggested reversible multilayeredALU with reversible QCA operation is *** 8-and 16-bit ALU,as well as logical unit functioning,is designed through fewer gates,constant inputs and *** implementation is designed on the Mentor Graphics QCA tool and verifies all functionalities.
