FFT/IFFT Block Floating Point Scaling




Introduction

The Altera® FFT MegaCore® function uses block-floating-point (BFP)
arithmetic internally to perform calculations. BFP architecture is a
trade-off between fixed-point and full floating-point architecture.
Unlike an FFT block that uses floating point arithmetic, a
block-floating-point FFT block does not provide an input for exponents.
Internally, a complex value integer pair is represented with a si ....etc

Low Power Consumption Using Dynamic Voltage Frequency Scaling
Abstract:
An effective mechanism for reducing processor power and energy.
In the last decade a lot of works have been done during the hardware and software implementation.
In this paper a proposed control loop of DVFS technique has been introduced.
Introduction:
In recent years the processors speed reaches Gigahertz, so the power dissipation increases rapidly in a level of the order of ten ....etc

Abstract
Smartcards are becoming the most secure and cheap portable computing device today. They have been used successfully in many applications involving money, proprietary and personal data. But, as smartcards get more powerful and become multiapplication, the need for database management arises. The design of very small databases for smartcards is constrained by the peculiar features of the physical medium. Also, smartcards have severe hardware limitations, which make traditional database technology irrelevant. The major task is to scale ....etc

Abstract

Interspecies allometric scaling, based on the assumption that a change in pharmacokinetic parameters correlates closely with body weight, can be described as an operation when a pharmacokinetic parameter of interest is scaled across species. This method has become a useful instrument in drug development, especially at the preclinical discovery stage, because the extrapolation facilitates the process of dosing transitions from animals to man and accelerates the drug testing and approval process. For greater extrapolation accur ....etc

VLSI Scaling for Architects



The Buzz is VLSI Wires are Bad

A lot of talk about VLSI wires
being a problem:
– Delay
– Noise coupling
• What are the characteristics of
chip wires?
– How do they compare to
scaled gates?
• And what does it really mean?
– To CAD developers
– To architects


Predicting the Future
• Is very difficult
– The only guarantee is:
The future will happen, and you will be wrong
• Two approache ....etc

Abstract:
Pharmacokinetic is mainly dedicated to the determination of the fate of substances administered externally to a living organism. In practice this discipline is applied mainly to drug substances, though in principle it concerns itself with all manner of compounds ingested or otherwise delivered externally to an organism, such as nutrients, metabolites, hormones, toxins and Pharmacokinetic models are designed to forecast the evolution of an endogenous or exogenous component on the tissues. To follow-up the evolution of the contr ....etc

Abstract:


Dynamic authority-based keyword search algorithms, such as ObjectRank and personalized PageRank, leverage semantic page link information to provide high quality, high recall search in databases, and the Web. Conceptually, these algorithms require a querytime PageRank-style iterative computation over the full graph. This computation is too expensive for large graphs, and not feasible at query time. Alternatively, building an index of precomputed results for s ....etc

2D TRANSFORMATIONS –TRANSLATION -SCALING
2D Transformation
 Given a 2D object, transformation is to change the object’s
 Position (translation)
 Size (scaling)
 Orientation (rotation)
 Shapes (shear)
 Apply a sequence of matrix multiplication to the object vertices
Translation
 Moving an object is called a translation. We translate a point by adding to the x and y coordinates, respectively, the amount the point should be shifted in the x an ....etc
