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

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

Abstract:
MANAGING MULTIDIMENSIONAL HISTORICAL AGGREGATE DATA IN UNSTRUCTURED P2P NETWORKS

A P2P-based framework supporting the extraction of aggregates from historical multidimensional data is proposed, which provides efficient and robust query evaluation. When a data population is published, data are summarized in a synopsis, consisting of an index built on top of a set of subsynopses (storing compressed representations of distinct data portions). The index and the subsy ....etc

Abstract

Multi-dimensional Visualization (hereafter, MDV) is to explore ways of graphically conveying useful information about digital library content to a user without confusing or overwhelming them. It seeks to present a user with an interactive graph of numeric and textual information gleaned from a semantic clustering system. Ultimately, the graphs will provide users with a system for efficient navigation through a document corpus. By graphically moving through a hierarchy of clusters, casual users and collection developers will browse ....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

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:


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

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
