Using the hardware given to the right, show the addition of two numbers in steps as it would take place.

A = 18.625,         B = 2.125

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 can present your answer preferably in a table. (If you wish, you can prepare your own Table to present your answer in better way)

Time Step-1	operation	R1	R2	..	..	C1	C2	…	Comments, if any
Time Step-2
