Question

write
the generate and propagate function and draw the
carry lookahead generator circuit​

Answer 1

Answer:

The function Pi = Ai ⊕ Bi is called the propagate function. Whenever Pi is equal to 1, an incoming carry is propagated through the bit position from Ci to Ci11. For Pi equal to 0, carry propagation through the bit position is blocked. The function Gi = Ai ⋅ Bi and is called the generate function.
