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 ...
This project focuses on designing two components: a 4-bit binary adder-subtractor and a 4-bit Arithmetic Logic Unit (ALU). Adder-Subtractor: The 4-bit binary adder-subtractor is designed to perform ...
Abstract: The article describes in detail the design of a 4-bit adder and subtractor. We will design the necessary sub-blocks for its proper functioning, such as a 2-bit multiplexer and a complete ...
