Integrated optics is a promising technology to take advantage of light propagation for high throughput chip-scale interconnects in many core architectures. A key challenge for the deployment of nanophotonic interconnects is their high static power, which is induced by signal losses and devices calibration. To tackle this challenge, we propose to us...
Les réseaux de neurones profonds ont permis des progrès sans précédent dans le domaine del’apprentissage automatique. En imitant le calcul parallèle et distribué du cerveau, de tels algorithmes permettant en effet d’émuler n’importe quelle fonction, jusqu’aux plus complexes. Leursapplications vont de la vision par ordinateur (classification, segmen...
In modern offshore racing, performance often depends on two main factors: a good autopilot and the right strategy decisions taken by the skipper. Some sensors are crucial to ensure the quality of those two keys of success, among which we can mention the heading sensors. Unfortunately, those sensors, whether magnetometers or GNSS based, are subject ...
With the proliferation of connected objects, the fine identification and the technical characterization of digital devices are one challenge for the monitoring and security of information systems. Connected objects are of different types, and each has different characteristics, whether it is the embedded operating system, their sensors or their fir...
The design of cyber–physical systems (CPSs) is facing the explosion of new functionalities requiring increased computation capacities and, thus, the introduction of multi-core processors. Moreover, some functionalities may impose precedence constraints between the programs implementing these new functionalities. While important effort has been dedi...
In many areas of the semiconductor industry, System-on Chip (SoC) power analysis and management is a critical process for maintaining low-power profiles. Due to the complexity of modern SoC designs and the definition of their power management strategies, it iscommon to reuse available resources such as Intellectual Properties (IP) and power intent ...
Since its 3.3 release, Modelica offers the possibility to specify models of dynamical systems with multiple modes having different DAE-based dynamics. However, the handling of such models by the current Modelica tools is not satisfactory, with mathematically sound models yielding exceptions at runtime.In this report, we illustrate this behavior on ...

Transiently-powered systems featuring non-volatile memory as well as external peripherals enable the development of new low-power sensor applications. However, as programmers, we are ill-equipped to reason about systems where power failures are the norm rather than the exception. A first challenge consists in being able to capture all the volatile ...
