Design of Resonant Clock Distribution Networks for 3-D Integrated Circuits

Giovanni De Micheli, Vasileios Pavlidis, Somayyeh Rahimian Omam

Designing a low power clock network in synchronous circuits is an important task. This requirement is stricter for 3-D circuits due to the increased power densities. Resonant clock networks are considered efficient low-power alternatives to conventional cl ...

Structured Derivation of Semi-Synchronous Algorithms

André Schiper, Martin Hutle, Zarko Milosevic, Fatemeh Borran, Hagit Albo Attiya

The semi-synchronous model is an important middle ground between the synchronous and the asynchronous models of distributed computing. In this model, processes can detect (timeout) when other processes fail. However, since detection is done by timing out, ...

Stability Study of a Complete Hydroelectric Production Site by Eigenvalues Analysis Method Based on Phase Variables

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Basile Kawkabani, Sébastien Alligné, Pedro Camilo de Oliveira e Silva

The eigenvalues analysis method is generally applied to synchronous machines by using d,q-components. This paper presents the application of this method on an equivalent model for the synchronous machine based on phase variables a,b,c instead of d,q-compon ...

Energy efficiency enhancement of sub-threshold digital CMOS

Omer Can Akgun

Power density and energy dissipation of digital IC's has become one of the main concerns during the recent years. With the increased usage of battery powered devices, ubiquitous computing, and increase in implantable biomedical applications, enhancing ener ...

Modeling synchronous systems in BIP

Joseph Sifakis

We present a general approach for modeling synchronous component-based systems. These are systems of synchronous components strongly synchronized by a common action that initiates steps of each component. We propose a general model for synchronous systems. ...

Of Choices, Failures and Asynchrony: The Many Faces of Set Agreement

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Set agreement is a fundamental problem in distributed computing in which processes collectively choose a small subset of values from a larger set of proposals. The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal ...

A Current Sensing Completion Detection Method for Asynchronous Pipelines Operating In the Sub-threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime the circuit delay, and hence, the leakage energy consumption depend on the supply voltage exponentially. By re ...

Energy Efficiency Comparison of Asynchronous and Synchronous Circuits Operating in the Sub-Threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime circuit delay, hence the leakage energy consumption depends on the supply voltage exponentially. By reducing t ...

Synchronous and Asynchronous Multiplexer Circuits for Medical Imaging Realized in CMOS 0.18um Technology

Rafal Tomasz Dlugosz

Multiplexers are one of the most important elements in readout front-end ASICs for multi-element detectors in medical imaging. The purpose of these ASICs is to detect signals appearing randomly in many channels and to collect the detected data in an ordere ...

Methodology for Risk Assessment of Part Load Resonance in Francis Turbine Power Plant

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Philippe Allenbach, Bob Greiveldinger

At low flow rate operation, Francis turbines feature a cavitating vortex rope in the draft tube resulting from the swirling flow of the runner outlet. The unsteady pressure field related to the precession of the vortex rope induces plane wave propagating i ...
