Email: ptvani@yahoo.com Abstract mate prefix addition is a technique for improving the race of binary addition. Due to continuing integrating intensity and the ontogeny needs of portable devices, low-power and superior designs are of prime importance. The unsullied parallel prefix common viper structures presented in the literature all over the years perfect for logical system depth, area, fan-out and interconnect count of logic circuits. In this paper, a new architecture for performing 32-bit Parallel affix addition is proposed. The proposed 32-bit prefix common vip er is compared with several Hellenic adders of uniform bit width in terms of power, keep and count of computational nodes. The results reveal that the proposed 32-bit Parallel Prefix adder has the least(prenominal) power delay product when compared with its peer vivacious Prefix adder structures. Tanner EDA tool was used for simulating the adder designs in the TSMC 180 nm and TSMC 130 nm technologies.

These bits make for generate and propagate signals used in addition. The output of the operator is a new pair of bits which is again combined retain a dot operator or semi-dot operator with separate pairs of bits. This procedural use of dot operator and semi-dot operator creates a prefix tree network which ultimately ends in the propagation of all carry signals.
