(10+ pts) Given a 1-bit full adder (you can use the box representation as below) show the circuitry required to make it into a 4-bit full adder and subtractor. Also show the hardware to compute the 4 primary flags for your 4-bit add/sub unit: carry (C), zero (Z), overflow (V), and sign (N). Remember, the Cou and Carry Flag are slightly different as we discussed in class. 5. (16 pts) Show the results for each of the additions/subtractions listed I'll give you specific numbers on the exam. Also show the equivalent decimal numbers for each Ain and Bin. NOTE: th for Ain and Bin are prior to any circuitry they are the raw inputs. e values given on the exam NA Sum INI D OUT 3 2 0 FLAGS ADD: Ain- Bin Bin SUM 3 2 0 FLAGS SUB: Ain Bin= in SUM (10+ pts) Given a 1-bit full adder (you can use the box representation as below) show the circuitry required to make it into a 4-bit full adder and subtractor.
