Virtual Prototyping Methodology for Power Automation Cyber-Physical-Systems

In this thesis, the author proposes a circular system development model which considers all the stages in a typical development process for industrial systems. In particular, the present work shows that the use of virtual prototyping at early stages of the ...

Distributed Rate Allocation in Switch-Based Multiparty Videoconferencing System

Pascal Frossard, Sergio Mena, Stefano D'Aronco

Multiparty videoconferences, or more generally multiparty video calls, are gaining a lot of popularity as they offer a rich communication experience. These applications have, however, large requirements in terms of both network and computational resources ...

Optically-Clocked Instruction Set Extensions for High Efficiency Embedded Processors

Edoardo Charbon, Ties Jan Henderikus Kluter, Claudio Favi, Christian Mester

We propose a technique to localize computation in Instruction Set Extensions (ISEs) that are clocked at very high speed with respect to the processor. In order to save power, data to and from Custom Instruction Units (CIUs) is synchronized via an optical s ...

High-speed power system stability simulation using analog computation: Systematic error analysis

Maher Kayal, Laurent Fabre, Ira Nagel

This paper joins a series of papers dealing with high-speed power system emulators. It clarifies the last details about the system level of the AC emulation approach by analyzing and quantifying the systematic errors introduced during modeling. Thereby a n ...

Virtual Infrastructure for Collision-Prone Wireless Networks

Seth Gilbert

Wireless ad hoc networks pose several significant challenges: devices are unreliable; deployments are unpredictable; and communication is erratic. One proposed solution is Virtual Infrastructure, an abstraction in which unpredictable and unreliable devices ...

Joint Hardware-Software Leakage Minimization Approach for the Register File of VLIW Embedded Architectures

Giovanni De Micheli, David Atienza Alonso, José Luis Ayala Rodrigo

New applications demand very high processing power when run on embedded systems. Very Long Instruction Word (VLIW) architectures have emerged as a promising alternative to provide such processing capabilities under the given energy budget. However, in this ...

MOVE Processors That Self-replicate and Differentiate

Yann Thoma, Joël Rossier, Pierre-André Mudry

This article describes an implementation of a basic multiprocessor system that exhibits replication and differentiation abilities on the POEtic tissue, a programmable hardware designed for bio-inspired applications. As for a living organism, whose existenc ...

An Architecture Design Methodology for Minimal Total Power Consumption at Fixed Vdd and Vth

Pierre-André Farine, Christian Piguet

This paper presents a new methodology allowing to compare several architectures (or microarchitectures) performing the same function and to select the one presenting the smallest total power consumption under fixed supply voltage (Vdd), threshold voltage ( ...

Continuous Profiling: Where Have All the Cycles Gone?

Monika Henzinger

This article describes the Digital Continuous Profiling Infrastructure, a sampling-based profiling system designed to run continuously on production systems. The system supports multiprocessors, works on unmodified executables, and collects profiles for en ...

Compiler and Software Distributed Shared Memory Support for Irregular Applications

Willy Zwaenepoel

We investigate the use of a software distributed shared memory (DSM) layer to support irregular computations on distributed memory machines. Software DSM supports irregular computation through demand fetching of data in response to memory access faults. Wi ...
