The parallel prefix adder is one of the fastest types of adder that had been created and developed. Two common types of parallel prefix adder are the Brent Kung and Kogge Stone adders. This project will compare and study the performances of these two adders in terms of propagation delay and design area. The comparison and study for both adders will be conducted for 8, 16 and 32 bits size. By using the Quartus II design software, the designs for both Brent Kung and Kogge Stone adders will be developed. From the designs of both adders, a vector waveform will be produced as a result of the designs’ simulations. The simulation result will also show the propagation delay for the adders. Hence, this project is significant in showing which of the two adders being tested perform better in terms of propagation delay and design area based on different sizes of bits.
