(a) In a multi-bit add operation, the input carry Cin is the most important information.
Therefore,
we introduce three carry status: delete (D), propagate (P), and
generate (G), to describe the carry status. Please write down the logic expression of D,
P, and G using the three inputs: A, B, and Cin.
D =
td =
P=
G=
(b) To construct a 16-bit adder, the most straightforward way is to use the ripple-carry
topology, which links all bit successively. Calculate the worst-case delay of ta if we
choose this topology. Assume fearry = 1 ns and Tsum = tcarry + tsum=2 ns.
