Carry-select adder

In electronics, a carry-select adder is a particular way to implement an adder, which is a logic element that computes the ( n + 1 ) {\displaystyle (n+1)} -bit sum of two n {\displaystyle n} -bit numbers. The carry-select adder is simple but rather fast, having a gate level depth of O ( n ) {\displaystyle O({\sqrt {n}})} .
