Hi, I need to design a circuit that adds two 4 bit numbers that are positive/positive, positive/negative, and negative/negative in two's compliment format.
The range is -7 to 8. I have set up a table matching the binary representation of each input. Now what?
I have been hinted that I would need to use XOR gates.
