Minimizing and Exploiting Leakage in VLSI Design /by Nikhil Jayakumar (Author), Suganth Paul (Author), Rajesh Garg (Author), Kanupriya Gulati (Author), Sunil P. Khatri (Author) .Power consumption of VLSI (Very Large Scale Integrated) circuits has been growing at an alarmingly rapid rate. This increase in power consumption, coupled with the increasing demand for portable/hand-held electronics, has made power consumption a dominant concern in the design of VLSI circuits today.

Traditionally, dynamic (switching) power has dominated the total power consumption of an IC. However, due to current scaling trends, leakage power has now become a major component of the total power consumption in VLSI circuits. Leakage power reduction is especially important in portable/hand-held electronics such as cell-phones and PDAs. This book presents two techniques aimed at reducing leakage power in digital VLSI ICs. The first technique reduces leakage through the selective use of high threshold voltage sleep transistors. The second technique reduces leakage by applying the optimal Reverse Body Bias (RBB) voltage. This book also shows readers how to turn the leakage problem into an opportunity, through the use of sub-threshold logic.

Mobile TV: Customizing Content and Experience /by Aaron Marcus (Editor), Anxo Cereijo Roib?s (Editor), Riccardo Sala (Editor) .This book will present significant projects and studies carried out in academia and in industry seeking to develop new mobile multimedia systems that go beyond mobile TV (in terms of purely media streaming) and are more enjoyable and relevant for the nomadic and peripatetic user.

To do this, it will showcase successful methodologies and new relevant solutions that extend the field of action of people on the move, improving, at the same time, the quality of their mobile experience.
The objectectives of the book are as follows:
* to gain insight into the future of mobile TV and mobile video in general;
* to explore the user-experience in mobile and pervasive interactive multimedia systems;
* to question the essential correlation between mobile video and users' context;
* to analyse how these systems can encourage the creation of mobile communities;
* to understand how these systems can be evaluated;
* to unveil relevant scenarios for mobile storytelling (creation and sharing);
* to understand how sociability can be achieved in nomadic contexts;
* to analyse how mobile digital content could evolve;
* to examine advanced interaction modalities for mobile video, and
* to discuss techniques to anticipate how nomadic cultures can shape trends in technology.
