This project implements a 4-bit Parallel Adder/Subtractor in Verilog using a Ripple Carry Adder (RCA) and logic gates like XOR, AND, and NOT. The design can perform both addition and subtraction based ...

This repository contains Verilog source files for a simple 4-bit signed calculator. The calculator can perform addition and subtraction using ripple-carry logic and detects overflow conditions. It was ...
