Question 49 |
The number of full and half-adders required to add 16-bit numbers is
8 half-adders, 8 full-adders | |
1 half-adder, 15 full-adders | |
16 half-adders, 0 full-adders | |
4 half-adders, 12 full-adders |
Question 49 Explanation:
For Least Significant Bit we do not need a full adder since initially carry is not present.
But for rest of bits we need full address since carry from previous addition has to be included into the addition operation.
So, in total 1 half adder and 15 full adders are required.
But for rest of bits we need full address since carry from previous addition has to be included into the addition operation.
So, in total 1 half adder and 15 full adders are required.
