Find the attached block diagram of the simple 2, four-bit manchester adders.
It can be generalized as below.

Boolean Equations:
1) Gi = Ai and Bi
2) Pi = Ai xorBi
3) Si = Pi xor Ci
4) Ci+1 = Gi or (Pi and Ci )
where
-- Gi -> carry generate of ith stage
-- Pi -> carry propagate of ith stage
-- Si -> sum of ith stage
-- Ci+1 -> carry out of ith stage
