4. Using the hardware given to the right, show the addition of two numbers in steps as it would take place. A= 8.625, B = -7.125 Show the steps in detail. Also show the contents of different registers (R1, .. R8) and control bits (C1, .. C9). It is noted that Control bits (C1, .. C9) could be either 1 or 0 and you can assign the logic levels for particular operations. You must present your answer in a Table, given below.
