Comment on the Sequential and Indeterminate Behavior of an End-Around-Carry Adder
نویسنده
چکیده
The sequential and indeterminate behavior of an end-around-carry (EAC) adder is examined. This behavior is commonly overlooked in the literature. Design modifications to impose determinism are provided. These modifications also eliminate the troublesome negative zero found in the one's complement number system.

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...
متن کاملA 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...
متن کاملThe Meaning and Esoteric Hermeneutics of: Then let them make an end of their unkemptness
In the 29th verse of the Hajj, the Holy Qur'an has commanded the pilgrims to say: "Then let them make an end of their unkemptness and pay their vows and go around the ancient House." On the What of "making the unkemptness" various meanings have been given by commentators. This article aims to analyze analytically the meaning of " making the unkemptness" in this verse in a descriptive-analytic m...

The purpose of this paper is to design a 64×64 bit low power, low delay and high speed Arithmetic Logic Unit (ALU). Arithmetic Logic Unit performs arithmetic operation like addition, multiplication. Adders play important role in ALU. For designing adder, the combination of carry lookahead adder and carry select adder, also add-one circuit have been used to achieve high speed and low area. In mu...
متن کاملModular Multipliers Using a Modified Residue Addition Algorithm with Signed-Digit Number Representation
In this paper, we present multipliers using a modified addition algorithm modulo m with a signed-digit(SD) number representation where m = 2 − 1, 2 or 2 + 1. To simplify an SD modular adder, new addition rules are proposed for generating the intermediate sum and carry with a binary number representation. By using the new codes for intermediate sum and carry and the end-around carry architecture...
