s n − 1 {\displaystyle s_{n-1}} . The carry-select adder design can be complemented with a carry-lookahead adder structure to generate the MUX inputs,...

A carry-save adder is a type of digital adder, used to efficiently compute the sum of three or more binary numbers. It differs from other digital adders...

A carry-skip adder (also known as a carry-bypass adder) is an adder implementation that improves on the delay of a ripple-carry adder with little effort...

Kogge–Stone adder (KSA or KS) is a parallel prefix form of carry-lookahead adder. Other parallel prefix adders (PPA) include the Sklansky adder (SA), Brent–Kung...
