Abstract

In this paper, we present a way to obtain efficient carry-skip adders, built with blocks of different sizes in VLSI technologies. We give some results about two-level carry-skip adders. We reduce our optimization problem to a geometrical problem, solved by means of an algorithm easily implemented on a microcomputer. Then we present an example of the realization of such an adder.
