Design And Implementation Of 64-Bit Ripple Carry Adder And Ripple Borrow Subtractor Using Reversible Logic Gates

Abstract

Minimal power design is desirable for a range of applications, including the Internet of Things (IoT), quantum computing, and so on. The reversible logic approach is at the foundation of a new technique for designing minimal power digital logic circuits for quantum computing applications. The reversible logic circuit offers a whole new approach to quantum computer processing. Reversible logic gates-based devices will be in high demand for future computer technologies since they require less power. Reversible logic gates were used to design a ripple carry adder (RCA) and a ripple borrow subtractor (RBS), which were simulated in Verilog 2018.3 and coded in Verilog HDL.
