5.3 Compute Co (in sum of product) of the carry-lookahead equation in terms of the G; P; and Co terms. Assume, all the P; and G terms are available, give the total number and type of logic gates needed to realize, Co. Include number of inputs to gates. Generalize to Cn. 5.5 Show the design of 2-bit adder with carry-lookahead generator as given in Figure 5.2.2 of the chapter.
