    Develop heterogeneous SoC homogeneously

    Hybrid system-on-chips increasingly integrate heterogeneous processors. However, developers see them as one component that they want to develop as integrated as possible. A homogeneous RTOS and hypervisor ecosystem for both MPU- and MMU-supported processors provides the critical convenience gain.

  • Development on Bare Metal vs. RTOS

    When developing embedded systems that are to be real-time capable, one of the first and most important questions is whether the applications should run under a real-time operating system (RTOS) or whether a bare-metal solution should be developed. Bare-metal programming is generally understood to mean that an application is written directly on the hardware without using an external programming interface, i.e. an operating system. Applications access here directly hardware registers of…

    Secure Communications in Rolling Stock

    While the EN standards 50128, 50129, 50126 and most recently EN 50657 have a strong focus on safety certification of COTS-based systems in the railway industry, they only partly deal with security issues. However, security is becoming more and more important, as closed systems are giving way to networked environments with wired and wireless connectivity. Safety-related systems in trains and signalling need to be protected from cyber threats in order to guarantee both integrity and availability.…

    Hypervisor in Space

    Development of certifiable systems and software for European Space Applications requires strict adherence to the ECSS standards. ECSS - the European Cooperation for Space Standardization - is a cooperation of the European Space Agency (ESA), national space agencies and the European Industry Association Eurospace with the aim of developing and maintaining coherent, commercially oriented and user-friendly standards for space applications. The main intention is to improve the performance and…

    Embedded Linux in Medical Technology

    Linux makes valuable contributions as a component of medical devices. Due to a large user base, security gaps are quickly detected and thus also closed. Of course, it also plays a role at this point that a professional team takes care of the maintenance of a Linux integration in medical devices and that the system is also regularly maintained. An optimal combination of a core development team and the use of open source can bring great advances in medical technology. The biggest advantage of…

    Improved real-time Positioning Data through PikeOS-based Augmentation Systems

    When people think of satellite-based GPS, they envision a high-tech satellite navigation system that can pinpoint locations worldwide to within a few meters. But global navigation systems (GNSS) such as the American GPS or the European Galileo struggle with many environmental interferences. So-called satellite-based augmentation systems (SBAS) improve the performance of these navigation systems by correcting their data. From 2022, the Korean peninsula will also benefit from the PikeOS-based SBAS…

    Browsing and Over-the-Air Updates peacefully united

    The electronic systems such as the anti-lock braking system inside a modern car are able to take control of critical systems such as the steering and braking gears. This significantly increases functional safety during vehicle operation, but at the same time also creates the risk of unauthorized access. Consequently, the functional safety of a vehicle must be supported by IT security measures. Real-time applications require deterministic response times, which can only be achieved with the help…

    Secure Factory Automation

    The continuing technological advancement that is enabling decreasing costs and greater compactness of devices make it possible to connect and control more physical elements in the industrial environment today. This is enabling industrial engineers to monitor processes with greater accuracy and drive OEE (Overall Equipment Effectiveness). At the same time separate operational technology (OT) systems are merging with enterprise IT infrastructure. However, this greater connectivity also brings more…

    Safety Certification of COTS-based Systems in Automotive Applications

    The ISO 26262 safety standard is a specialization of the general IEC 61508 functional safety standard and defines generic (software) applications and generic (hardware) products that can receive independent certification for automotive applications. When building a complex safety system, such commercial-off-the-shelf (COTS) products can be reused, including their existing certification artifacts. With this approach, safety-related electronics can be assembled from pre-certified software and…

    IT Security Architecture for the next Generation of Control and Safety Technology

    With the increasing use of networked digital technologies in safety-critical areas of railway operations, the requirements for cyber security, which must be considered together with functional safety, are growing. In the HASELNUSS project, a safety platform is being developed that allows the joint operation of safety and security applications on one system.
