Cyber-Physical Systems in Competition Sailboats: a challenging case study for a wide range of future applications.

Jean-Philipe Diguet, LAB-STICC, Université de Bretagne-Sud.

Competition Sailboats have continuously pushed the performances barriers over the last decades (e.g. 2012 sail word tour record: 45days). The history of improvements relies on a combination of technical leaps including materials, designs and shapes of hulls and sails, and navigation techniques. As observed in automotive and avionics, a growing number of advanced sensors and embedded systems have become necessary to achieve such results but the relation with a set of highly variable physical values is intrinsically much stronger. Measurements and modeling of values such as wind, currents, swell, as well as mechanical efforts and many others, are now necessary. As a fact, competition sailboats are particularly interesting cases of cyber-physical systems (CPS), which may result in innovations in a wide range of application domains.

The talk will first present the requirements and challenges inherent to this specific context. Then, an overview of involved techniques and technologies will be given.  It includes a panorama of used and expected sensors, signal processing needs for data estimation and autopilots, as well as requirements in terms of digital communications for on boat networks, media broadcast or communications with sensor-equipped buoys or remote servers delivering forecast or navigation services. Human/Machine interface is also an important area of investigation that is considered. The last part will detail a real case study that addresses drift estimation on some of the most advanced racing sailboats, the objective is the improvement of boat speed and wind angle estimations. In conclusion a projection will be carried out on future and possible applications.

He has been an associated professor at UBS University (France) from 1998 until 2002. In 2001 he obtained an the Anvar emergence prize and co-funded dixip in 2003 in the area of wireless embedded systems. Since 2004 he is a CNRS researcher at Lab-STICC (France), where is heading the MOCS team. He has been visitor researcher at the University of Queensland (Australia) in 2010. Over the last ten years, he has been the supervisor of 16 PhD thesis and involved in 10 cooperative funded projects. Historically his research activity focus on hardware/software codesign including CAD tools for synthesis of heterogeneous multiprocessor SoC. The second part of his work targets self-adaptive hardware and software architectures, which implement autonomous configuration decisions (e.g. smart cam, security, digital communications). The last topic is the design of distributed and networked embedded systems for pervasive computing, with two main application fields: remote healthcare and smart sailing boats.

Design of Future Integrated Systems: A Cyber-physical Systems Approach.

Radu Marculescu, Carnegie Mellon University.

Continuous technology scaling allows hundreds and soon thousands of processing cores to be integrated on the same chip; this represents the multi-core computing paradigm which makes it possible to run multiple heterogeneous applications concurrently on a single chip. However, the on-chip power consumption represents one of the major bottlenecks in providing increased performance and enhanced capabilities for such platforms. Indeed, increased power consumption results not only in higher on-die temperature and reduced lifetime reliability, but also leads to faster discharge of battery-powered mobile or implantable devices targeting embedded or health-care applications.

In this talk, we address some fundamental issues related to the modeling and optimization of power and performance of next generation of integrated systems while taking a cyber-physical approach. As such, the focus of the design methodology is not only on establishing a reliable communication infrastructure between the computational elements, but also on including time, communication, and feedback-based control as intrinsic components of the programming model; this goal allows us generalize the classical computational paradigm such that more direct interaction between the cyber-system and physical world becomes possible.

Starting from these overarching ideas, we argue that the complex requirements for high-performance and low-power design, as well as reliable and safe operation of future integrated systems call for a truly multidisciplinary approach which brings together concepts and techniques from real-time computing and signal processing, multiprocessor architecture and OS design, as well as distributed and self-organized control.

Keynote Talk 3 (Fri. Oct. 19, 9:00–9:45)

Taming and Exploiting Unreliable Embedded Memories.

Nikil Dutt, University of California, Irvine

While designers have traditionally dealt with unreliable embedded memories through standard fault-tolerant techniques in the past, aggressive technology scaling and low-voltage operation (to save power) pose significant reliability challenges for emerging platforms with distributed embedded memories. In this talk, I will first survey a series of hardware and software schemes that both ameliorate poor reliability, and exploit unreliable embedded memories through hardware and software mechanisms in order to achieve a low-power, fault-tolerant memory space, and keep production yield at tolerable levels. Then I will explore the benefits/drawbacks of various schemes and motivate the need for, and present Embedded RAID-on-Chip (E-RoC), a holistic hardware/software strategy that virtualizes the user memory space and exploits unreliable distributed embedded memories for reduced power consumption, better reliability and enhanced security. The talk concludes with thoughts on how to manage distributed on-chip memories for scalable many-core architectures.
