A MARTE-Based Design Pattern for Adaptive Real-Time Embedded Systems

The design of adaptive real-time & embedded systems (RTES) is a hard task due to the complexity of both software/hardware features and the variability in the operational environment. This paper presents a new design pattern intended to support and facilitate the co-modeling and scheduling analysis of RTES. The contribution of this pattern is that is designed to i) support scheduling analysis allowing adaptation mechanisms ii) model all the software/hardware features and allocation in the same view iii) annotate the system with functional and non-functional properties using a high-level modeling language. The generated model from the pattern contains all the needed information to perform the schedulability tests. As a proof of concepts, we present experimental results for an automobile system.
