MARS = MRAM based Architecture for Reliable and low power Systems, aka "un mars et ça repart" [2011..2013]
  • official site
  • Head leader: Lionel Torres LIRMM
  • Partners: CEA List, EADS/Innovation Works, IEF, LRI, Spintec and CNRS
  • The MARS project aims
    • To explore the contribution of such technologies, including the integration of non-volatile MRAM technology (Magnetoresistive Random Access Memory)
    • Identifying and quantifying the levels and systems architecture benefits especially in terms of reliability, energy consumption and performance.
    MRAM technology offers very interesting performances for non-volatile memory: access time (order of several nanoseconds), four times the density of SRAM, robustness against SEU (Single Event Upset), energy, endurance ... etc. To facilitate the use of this technology, it is necessary to identify and quantify the benefits that we may get in a context of critical embedded applications, particularly in the field of aeronautics and space. For instance, the robustness of this technology considering SEU is probably an important way of development for this technology. However it is clear that efforts in this project can be adapted to wider application areas.
    Our efforts will be on the suitability of this technology based on embedded processors architectures with a focus on two aspects:
    • The core of the processor and associated memory hierarchy. Regarding the processor core it is clear that innovative solutions will emerge from the technological advances of MRAM, either at the architectural level or logic level while optimizing Reliability / Energy / Performance.
    • To the memory hierarchy that extends from the registers to the mass memory through the cache, the non-volatility and intrinsic qualities of MRAM will allow to propose new paradigms of storage access within a processor or system in general.
    The main novelty of this project is to focus architecture level, at the interface between advanced technology providing a new and profound review on the design of microelectronic embedded systems incoming from the MRAM technology.
  • IEF & LRI jobs: to evaluate the impact of MRAM on cache (memory architecture) performance and the impact of coding (software optimizations) of general purpose codes (security, CRC), and domain specific codes (image processing) on power consumption

Surveillance imProved sYstem [2010..2013]
  • official site
  • Head leader: EADS/Cassidian
  • SPY goal is to design and evaluate a new autonomous architecture for intelligent video-surveillance for still and mobile systems. SPY will emphasize on better use of wireless network, and mobiles sensors (mike and CCTV camera) to help policemen and firemen to accompish their duty. SPY project will implement advanced algorithms to provide an autonomous support to assist decision making at the tactical level.

Optimization and Parallelization for Analysis and Reconstruction of ultrasonic non-destructive testing. [2010..2013]
  • Head leader: CEA List/CIVA
  • Partners: EADS/Airbus, EDF-R&D, Cap Entreprise M2M
  • The project OPARUS "Optimization and Parallelization for Analysis and Reconstruction of ultrasonic NDT" focuses on the development of modelling tools and treatment for reconstruction of multi-element ultrasonic non destructive testing data. The objective of the project is to optimize the performance of numerical algorithms and to extend significantly the actual limitations on the use of accurate models for visualization, analysis and diagnostic and provide tools for innovative modelling in agreement with the industrial constraints. The kinds of technology pointed are clearly oriented on multi-core processors and GPGPU, all included in single "workstation". The technological barriers concerns both the capacity to exploit the new parallel architectures and to implement optimized algorithms dedicated to the reconstruction of data for analysis. The developments are focused on applications representative of industrial cases. The reconstruction tools based on these developments will be integrated into three systems and software: the M2M acquisition systems, CIVA platform of simulation and analysis and the analysis production software NDT-kit. OPARUS is a 3 years industrial research project which includes industrial end users of NDT (EADS and EDF), high-tech companies, (M2M, which develops multi-elements systems and CAPS-Enterprise, expert in parallel computing solutions), CEA LIST developing the CIVA software platform, and EFI, university laboratories specialist of parallel architectures, image processing and complex systems. Project results will be directly integrated in systems and software already operating in industrial environments. From a scientific point of view results will be communicated through journals and conferences dedicated to non destructive testing, and in journals for research in computer science and architecture.

  • official site
  • head leader: Thales Research and Technology TRT
  • our job: to develop tools to help user to optimize deployment of large applications over the Teraops parallel plateform. Tools should tackle combined problems of data flow parallelization and Control Flow Parallelization. We are working on low level image processing algorithms (typically convolution kernel) optimization and also intermediate/medium level image processing algorithms (connected component labeling, hysteresis threshold, 2D convex Hull, ...) that are data dependant.
