Design a 32-bit carry look-ahead adder. It has two inputs A and B, each of 32 bits and one 1-bit

Design a 32-bit carry look-ahead adder. It has two inputs A and B, each of 32 bits and one 1-bit "enable input". The sum and carry out of CLA is given as: Si = Pi + Ci . * Ci + 1 = Gi+ Pi * Ci, where, Gi=AiBi and Pi = Ai Bi are called carry generate and carry propagate respectively. These equations show that a carry signal will be generated in two cases: i. if both bits Ai and Bi are 1 ii. if either Ai or Bi is 1 and the carry-in Ci is 1. If you apply these equations to a 4-bit adder: i. C1 = GO+ POCO ii.
