In case of the parallel adder, the speed with which an addition can be performed is governed by the time required for the carries to propagate or ripple through all the stages of the adder. Which of the following statements are correct?
(A) The method of speeding up the addition process is based on additional functions of full adder called carry generate and carry propagation.
(B) The look-ahead carry adder speeds up the process by eliminating ripple carry dely.
(C) The final sum output of the nth stage is given by Sn = Pn ⊕ Cn where Pn = An ⊕ Bn
(D) The final carry output of nth stage is given by Cn+1 = Gn + Pn where Gn = An ⋅ Bn

Concept:- Carry look-ahead adder
→ In the case of the parallel adder, the speed with which addition can be performed is governed by the time required for the carries to propagate or ripple through all of the stages of the adder.
The look–ahead–carry adder speeds up the process by eliminating this ripple carry delay.
→ It examines all the input bits simultaneously & also generates the carry-in bits for all the stages simultaneously.

 
→ Consider the circuit:-
Si = Pi ⊕ Ci
& Pi = Ai ⊕ Bi
Gi = Ai ⋅ Bi
Ci + 1 = Pi Ci + Gi
So, Statements A, B & C are correct only.
