Abstract
Integer addition is one of the mast important operations in digital computer systems because the performance of processors is significantly influenced by the speed of their adders. This paper proposes a delay insensitive, carry-lookahead adder in which the logic complexity is a linear function of n, the number of inputs, and the average computation time is proportional to the logarithm of the logarithm of n. We also show an economic implementation of this adder in CMOS technology.
