-6 -5 For each number set, complete the following operations and predict what your output sums and carries should be. You should also note if overflow has occurred. Remember overflow occurs when you add two positive numbers and the result is negative or vice versa. Addition overflow cannot occur if one number is positive and the other is negative. Subtraction overflow occurs if the signs are different and the sign of the result is the same as the subtrahend's (bottom number's) sign. Subtraction overflow cannot occur if the signs of both numbers are the same. Set #1: ADD A= 1 A3 A₂ A₁ Ao B3 B₂ B₁ Bo Set #2: ADD 7 A= A3 A₂ A₁ Ao B3 B₂ B₁ Bo

3) Determine the sum generated by the 3-bit parallel adder in Figure 6-8 and show the intermediate carries when the binary numbers 101 and 011 are being added. FIGURE 6-8 A B C A B C 1175 FA2 A B C FA3 Cout E FAI
