Abstract
The Parallel Prefix
Adder (PPA) is one of the fastest type of adders that had been created and
developed from carry look ahead adders. Three common types of parallel prefix
adders are Brent-Kung, Han-Carlson and Kogge-Stone adders. This research
involves an investigation of the performances of these three adders in terms of
computational delay, Power, Speed and design area. The investigation and
comparison for these adders was conducted for a 16 bit size. By using the
Xilinx 14.5 design software, the designs for Brent Kung, Han-Carlson and Kogge
Stone adders were developed. Comparison of area, delay, speed and area for 16
bit Kogge Stone, Han-Carlson and Brent Kung adders show that the Kogge Stone
adder is best in terms of speed and the reduced area is obtained from the
Han-Carlson adder. The results and simulation are verified using Xilinx 14.5
software.
