Adder is the most basic functional module, and is widely used to multiplier, divider and others. Therefore high speed adder must be developed for the fast operation. Though various types of adders were proposed, quantitative evaluation has not been performed yet. In this paper, we give the quantitative evaluation for each adders by 4 terms of power consumption, area, gates, and delay time by using hardware description language. From the results, it is clear that the sign digit (SD) adder is better than the others.
