1. How could you use your ALU to compute a bitwise Xor function of two 8-bit numbers? [Hint: you might need to use it multiple times.] 2. Would you expect your ALU to run faster, i.e. take less time for its output to stabilise at a true or false value, when f is zero or when f is one? Briefly explain your choice. 3. What extra input and output would you need to add to your 8-bit ALU to make it useful for adding 16-bit numbers, either in a sequential circuit or in software?
