A 8 bits register that can do multiple operations
A demonstration of how to make it work with bigger values is included
Experiment 4
Here, I have created a 4-bit BPA (Binary Parallel Adder) using 4 full adder circuit. Here A0/B0 is LSB (Least Significant Bit) and A3/B3 is MSB (Most Significant Bit). This circuit can perform 4-bit binary addition of two numbers.
