During system synthesis (i.e., task allocation) the transmission of messages between tasks is usually addressed in a simplistic way. If a message is exchanged via an external bus, it is assumed each message is packed in an individual frame. This assumption leads to an overestimation of bus bandwidth demand and frame response time. For some systems (i.e.,(More)
Smart maintenance constitutes an essential concept in Industry 4.0, where industrial devices report their maintenance status to remote back end systems and thus predictive maintenance can be intelligently scheduled and carried out locally at the affected device. This status data must be securely assignable to the claimed device identities when transmitted(More)
When designing a distributed computing-system, the communication networks are a key determining factor for system's performance. A common approach is to minimize bandwidth-consumption, while other important objectives -- maintainability, extensibility, robustness -- get less attention in the literature. In this work we provide a design-methodology how to(More)
In modern embedded systems, e.g. avionics and automotive, it is not unusual for there to be between 40 and 100 processors with a great deal of the software having hard real-time requirements and constraints over how, when and where they execute. The requirements and constraints are essential to the overall systems dependability and safety (e.g. to ensure(More)
An environment involving large scale development has a tendency to repeatedly designing functional blocks amongst different groups from several domains. To avoid at least a part of these problems a general architecture can be planned within an organization to facilitate reuse. This offers benefits such as cost savings, lower redundancy, improved(More)
The advent of initiatives like Industry 4.0 promises increased operational efficiency through smart services and interconnected devices. To enable smart maintenance services for today's and future industrial equipment, regular status information must be transmitted from device customers to maintenance service providers over the Internet. However, simply(More)
