Nanosystems: devices, circuits, architectures and applications

Professor Giovanni De Micheli, EPFL, Lauzanne

Much of our economy and way of living will be affected by nanotechnologies in the decade to come and beyond. Mastering materials at the molecular level and their interaction with living matter opens up
unforeseeable horizons. This talk deals with how we will conceive, design and use nanosystems, i.e., integrated systems exploiting nanodevices.  Whereas switching circuits and microelectronics have been the enablers of computer and communication systems, nanosystems have the potentials to realize innovative computational fabrics whose applications require broader hardware abstractions, extended software layers and with a much higher complexity level overall.  The abstraction of computation, the nanosystem architecture, the technological feasibility envelope and the multivariate design optimization problems pose challenging and disruptive research questions that this talk will address.

nanniGiovanni De Micheli is Professor and Director of the Institute of Electrical Engineering and of the Integrated Systems Centre at EPF Lausanne, Switzerland. He also chairs the Scientific Committee of CSEM, Neuchatel, Switzerland. Previously, he was Professor of Electrical Engineering at Stanford University. He holds a Nuclear Engineer degree (Politecnico di Milano, 1979), a M.S. and a Ph.D. degree in Electrical Engineering and Computer Science (University of California at Berkeley, 1980 and 1983). His research interests include several aspects of design technologies for integrated circuits and systems, such as synthesis, hw/sw codesign and low-power design, as well as systems on heterogeneous platforms including electrical, micromechanical and biological components. He is author of: Synthesis and Optimization of Digital Circuits, McGraw-Hill, 1994, co-author and/or co-editor of eight other books and of over 400 technical articles . He is, or has been, member of the technical advisory board of several companies, including Magma Design Automation, Certess, Coware and STMicroelectronics. Prof. De Micheli is the recipient of the 2003 IEEE Emanuel Piore Award for contributions to computer-aided synthesis of digital systems. He is a Fellow of ACM and IEEE. He received the Golden Jubilee Medal for outstanding contributions to the IEEE CAS Society in 2000. He received the 1987 D. Pederson Award for the best paper on the IEEE Transactions on CAD/ICAS, two Best Paper Awards at the Design Automation Conference, in 1983 and in 1993, and a Best Paper Award at the DATE Conference in 2005. He has been serving IEEE in several capacities, namely: Division 1 Director (2008-9), co-founder and President Elect of the IEEE Council on EDA (2005-7), President of the IEEE CAS Society (2003), Editor in Chief of the IEEE Transactions on CAD/ICAS (1987-2001). He is and has been Chair of several conferences, including DATE (2010), pHealth (2006), VLSI SOC (2006), DAC (2000) and ICCD (1989). He is a founding member of the ALaRI institute at Universita' della Svizzera Italiana (USI), in Lugano, Switzerland, where he is currently scientific counselor.


From Smart Pacemaker to Remote Monitoring of Cardiac Function

Dr. Alain Ripart – Sorin Group CRM
Implantable cardiac pacemakers and defibrillators have known recently a tremendous growth and over 800.000 units are implanted worldwide every single year.
Ageing people, electronic miniaturisation and performance, increase of medical indications largely proven by clinical data, are the key drivers of the market.
These microsystems associate multiple MEMS based sensors like accelerometers, low current microprocessors with high density static memories. The whole, powered by a lithium battery is encapsulated in a hermetic titanium capsule.
Programming of the device is performed via a RF bidirectional communication with a desktop microcomputer, which analyses and stores locally the clinical data.
The main informations, stored in the device may be sent remotely from the patient at home, at periodic intervals, to the hospital.
This allows active surveillance in order to diagnose and prevent problems before any serious complication or emergency hospitalization.

ripartAlain Ripart is Senior Vice-President and Chief Scientific Officer of Sorin Group CRM. His main missions include scouting for new technologies and new applications for arrhythmia diagnosis management and therapy with implantable devices as well developing cooperative research with academic and private partners. From November 1987 to April 2005 he was Vice President of ELA Medical, the French pacemaker manufacturer he co-founded in 1977. Previously he was a research engineer in the biomedical “ELectronique Appliquée department where he developed various cardiac monitoring devices, defibrillators, and pacemakers. He graduated from ENSEEIHT where he obtained an Engineer Diploma; he also owns a PhD in Electronics. Alain Ripart is member of the SEE, the ESC (EU Society of Cardiology), and FHRS (Heart Rhythm Society USA). He co-edited 4 books on cardiac pacing.

Energy-saving approaches for warehouse-scale computing

Dr. Wolf-Dietrich Weber, Google

This talk discusses the energy saving approaches that apply to warehouse scale computers, with particular emphasis on experience at Google. The talk presents data on the utilization levels of individual components and entire machines running large-scale services like web search. By looking at idleness at different time scales, we can estimate the energy savings potential of different techniques that are available today. In addition, we point to how system and circuit designers can help improve the overall picture in the future.

Wolf-Dietrich Weber holds a Ph.D. in electrical engineering from Stanford University. His academic research was in the area of computer architecture, particularly distributed cache coherence protocols. His work has taken him into server, chip, and on-chip network design. For the past 5 years, he has been working in an infrastructure group at Google, focusing on performance, power, and reliability issues of Google's server fleet.
