This project is a hardware-only 4-bit binary adder-subtractor circuit built using DIP switches, TTL logic ICs, and seven-segment displays. It performs addition and subtraction of two 4-bit binary ...

Abstract: Reversible logic has gained the interest of many researchers due to its applicability in emerging low power technologies such as Quantum computing, QCA, optical computing etc., ...

Abstract: In this paper, an n-bit Quantum Binary Adder-Subtractor (QBAS) is designed using quantum logic gates using IBM Qiskit. A comprehensive understanding of the principles of quantum computing ...

Anyone reading this uses computers, and a few very cool people have built their own computer out of chips, [zaphod] is doing something even cooler over on hackaday.io: he’s building a computer from ...

In Part 1 of this two-part binary coded decimal (BCD) extravaganza, we introduced a bunch of bodacious concepts, including the binary (base-2) number system, binary logic, binary computers, and bits, ...

This Verilog module implements a 4-bit Adder-Subtractor circuit, allowing both addition and subtraction operations based on a control signal. The design uses simple combinational logic to compute the ...
