چکیده

Parallel prefix addition is a technique for speeding up binary addition. Classical parallel prefix adder structures developed so far are optimized for logic depth, area, fan-out and interconnect count of logic circuits. Due to continuing integrating intensity and growing needs of portable devices, low-power and high-performance designs are of prime importance. A new technique, proposed for performing parallel prefix addition, has least power delay product in comparison with its peer prefix adder structures. Tanner EDA tool was used for simulation in TSMC 180 nm technology.

Fast Mux-based Adder with Low Delay and Low PDP

Adders, as one of the major components of digital computing systems, have a strong influence on their performance. There are various types of adders, each of which uses a different algorithm to do addition with a certain delay. In addition to low computational delay, minimizing power consumption is also a main priority in adder circuit design. In this paper, the proposed adder is divided into s...

A High-Speed Dual-Bit Parallel Adder based on Carbon Nanotube ‎FET technology for use in arithmetic units

In this paper, a Dual-Bit Parallel Adder (DBPA) based on minority function using Carbon-Nanotube Field-Effect Transistor (CNFET) is proposed. The possibility of having several threshold voltage (Vt) levels by CNFETs leading to wide use of them in designing of digital circuits. The main goal of designing proposed DBPA is to reduce critical path delay in adder circuits. The proposed design positi...

4 Parallel Prefix Adder

VLSI Integer adders find applications in Arithmetic and Logic Units (ALUs), microprocessors and memory addressing units. Speed of the adder often decides the minimum clock cycle time in a microprocessor. The need for a Parallel Prefix Adder (PPA) is that it is primarily fast when compared with a ripple carry adder. PPA is a family of adders derived from the commonly known carry look ahead adder...
