Component-based models for runtime control and monitoring of embedded systems

Abstract

Nowadays, more and more developments in the embedded systems domain are based on components and abstract models. However, while the design becomes more abstract, control and monitoring during runtime are often performed on low abstraction levels. In contrast to this low level access we present a seamless design flow for adjustment and error identification using abstract component-based models. We develop an extended metamodel to describe components and their platforms and the connection between the model and the real hardware. Furthermore, we integrate on model level platform abilities for control and especially debugging to support for example real-time recording. From a user's perspective the system is designed, controlled and monitored on model level. We discuss different methods concerning runtime control and monitoring of resource constraint systems. We demonstrate the concept's applicability based on two exemplary use cases: wireless sensor network application engineering and reconfigurable hardware development.
