Use another full adder/subtractor circuit to add 7 to the result of part (iii) and connect this result to four output pins. C. (note: when using your full adder/subtractor circuits, you do not need to use the N,Z,V,C output flags right now, so do not connect them to anything). Hand in a screen shot of your schematic. D. Show the circuit output when the following values are input using the excess 7 represen- tation: i. A=+1, B=-2 ii. A=+2, B=+4 iii. A=-1, B=-3 E. Verify the bitwise calculations of your circuit in part D by hand. Is your circuit accom- plishing the addition of two excess 7 values? F. Simplify the calculation ((A − 7) + (B − 7) + 7) in order to create a simpler circuit and re-run your tests from part D. G. How might this circuit be used if multiplying IEEE754 formatted floating point numbers?
