  2. 33. Mixed-Criticality Systems (MCS): Introduction and State of Practice
    Dr Francisco J. Cazorla (Barcelona Supercomputing Center and IIIA-CSIC)

    Across all real-time domains companies aim at increasing their competitive edge by offering additional functionalities and services on every new product release. With the aim of reducing costs, functionalities with different criticalities are executed sharing various hardware components. However, without appropriate preconditions, integrating mixed-criticality functionalities onto the same...

  3. 34. Mixed criticality and partition systems
    Mr Alain Rossignol (Airbus Defence and Space), Mr Luc Planche (Astrium)
    19/10/2016, 15:00
    After R&D studies on Integrated Modular Avionics (IMA) architecture and process, after definition and development of Time & Space Partitioning solutions with Hypervisors & Separation Kernels, the first space operational use cases are starting, with the need to maximize the integration of different functions & sensors software inside the same computer. Depending on the mission and the...

  4. 35. Iridium Next STR S/W: a first step towards mixed criticality in OBSW
    Mr Guillaume Veran (Thales Alenia Space - France)
    19/10/2016, 15:30
    The migration of spacecraft functions from hardware to software together with a higher centralization is one of the current ways to reduce the cost of spacecraft avionics. This requires to manage mixed criticality software in the main platform computer. The integration of a star tracker software (MHSTR SW) in Iridium Next platform software was a major step in this direction for TAS-F. This...

  5. 38. TSP architectures for OBSW in CNES
    Mr Julien Galizzi (CNES)
    19/10/2016, 16:00
    The lessons learnt from the CNES projects are that the institutes involved in the payload developments have to systematically develop general “non-scientific” features, such as boot, platform interface, FDIR, I/O, timing, mass memory interface, etc. CNES have therefore initiated some years ago generic developments in order to offer off-the-shelf building blocks that could be easily reused with...

  6. 36. (On the way to) Success Stories From Non-Space Domains
    Dr Francisco J. Cazorla (IIIA-CSIC and BSC), Mr Jon Perez (IK4-IKERLAN)
    19/10/2016, 17:15
    The development of mixed-criticality systems that integrate applications of different criticality (e.g., safety) in a single embedded system can provide multiple benefits such as product cost-size-weight reduction, reliability increase and scalability. However, the integration of applications of different levels of criticality in a single embedded system leads to several challenges with...
