Abstract : Addition is important in many of data path subsystems. The primary factor for any design is to reduce the power
dissipation and to increase the performance. To achieve the performance and to reduce the power dissipation, selection of
adder topology is an important thing. The use of parallel prefix adders (PPA’s) increases the performance by reducing the
power dissipation. This paper represents the comparison between the different prefix trees and the implementation of radix-
4, 32 bit parallel prefix adder with sparseness of 4. The work involves the implementation of radix-2 and radix-4 32 bit
parallel prefix adder structures by comparing power, delay, power delay product and number of computational nodes. The
comparison result reveals that radix-4, 32 bit parallel prefix adder realizes minimum power and delay. The power and delay
of both the adders are analyzed and compared. Cadence sim vision tool used for verilog implementation and Cadence
virtuoso tool used for schematic implementation and the Encounter tool is used for the physical design of the both the
adders.
Keywords —Parallel prefix adders, arithmetic and logic unit, Power delay product.
