Kogge-Stone Adder

The Kogge-Stone adder is a parallel prefix form carry look-ahead adder. It generates the carry signals in O(log n) time, and is widely considered the fastest adder design possible. It is the common design for high-performance adders in industry.

It greater area to implement than the Brent-Kung adder, but has a lower fanout at each stage which increase performance. Wiring congestion is often a problem for Kogge-Stone as well.
