16 Bit Adder this adder uses Kogge Stone Algorithm the idea here we have essential node thats initialize the adder dynamic node this node varies each state it takes p,g and generate new p,g for the essential node p , g equation g = a AND b //////////////// p = a XOR b /////////////// for the dynamic node ////////////// g = g1 + p1 g0 ////////////// p = p1 p0 /////////////// the carrier equation /////////////// c0= g0 + p0 g0 ////////////// c1= g1 + p1 c0 ////////////// and so on ////////////// for the summation equation ////////////// a XOR b XOR c ////////////// the input carrier equlal zero
