Question: 6. Using 4 bit 1's complement (B2O), add the two operands Op1 and Op2 below, using the methods described in class for adding 1's complement


6. Using 4 bit 1's complement (B2O), add the two operands Op1 and Op2 below, using the methods described in class for adding 1's complement numbers correctly (Remember that the hardware needs to determine what bit value to use as the first carry, and that in some cases, 2 addition operations are required). a. How does the hardware (the addition unit in the CPU) determine if a second addition operation is required? ANSWER: b. Is a second addition operation required in this case? ANSWER: c. If a second addition is required, what is added back to the first sum from above to get the final correct result? ANSWER: d. If you interpret the result as a 1's complement value, is it the correct result? ANSWER: [] Yes [] No
