    Freedom from interference for AUTOSAR-based ECUs: a partitioned AUTOSAR stack
    (Automotive - Safety & Security 2012, 2012) Haworth, David; Jordan, Tobias; Mattausch, Alexander; Much, Alexander
    AUTOSAR1 is a standard for the development of software for embedded devices, primarily created for the automotive domain. It specifies a software architecture with more than 80 software modules that provide services to one or more software components. With the trend towards integrating safety-relevant systems into embedded devices, conformance with standards such as ISO 26262 [ISO11] or ISO/IEC 61508 [IEC10] becomes increasingly important. This article presents an approach to providing freedom from interference between software components by using the MPU2 available on many modern microcontrollers. Each software component gets its own dedicated memory area, a so-called memory partition. This concept is well known in other industries like the aerospace industry, where the IMA3 architecture is now well established. The memory partitioning mechanism is implemented by a microkernel, which integrates seamlessly into the architecture specified by AUTOSAR. The development has been performed as SEooC4 as described in ISO 26262, which is a new development approach. We describe the procedure for developing an SEooC.

    Workflow-supported Creation and Administration of XML-based Sustainability Reports
    (Managing Environmental Knowledge, 2006) Isenmann, Ralf; Jordan, Tobias; Gomez, Jorge Marx
    Sustainability reporting is an approach striving for sustainable development which meets environmental, economical and social aspects. It is supported by indicators for sustainable managing as well as by the integration of external costs. In this paper we present the conception of a software prototype for workflow-supported creation and administration of XML-based sustainability reports.
