For my CCOM 3030 class
3 bit counter
Computer Systems Architecture
32-bit ALU, only with AND, OR, and ADDER/SUBTRACTOR.
A simple adder that adds two 4-bit integers and returns the result on a hex display.
It also keeps track of the flags.
It can also subtract if the ADD/SUB is 1
ADD/SUB = 0 => add
ADD/SUB = 1 => sub
