Abstract :
This paper explores a variation of the Han-Carlson adder for large word sizes and compares the performance of the new design with the traditional design. This work introduces a second type of design with two Brent-Kung stages each at the beginning and at the end and with Kogge-Stone stages in the middle, henceforth referred to as the “Hybrid Han-Carlson design.” With the new design, the Hybrid Han-Carlson adder, the delay increases slightly, but the complexity, silicon area and power are reduced significantly.
