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 ...
We built a 4-bit Arithmetic Logic Unit (ALU) using Verilog HDL that runs on the DE1-SoC FPGA board. The ALU takes two 4-bit numbers as inputs through switches on the board and performs one of four ...
