“…Multi-mode techniques have also been explored at the architecture level, where a mode corresponds to a configuration. Each mode is a set of active resources, a local schedule on each resource, and a network configuration [16]. A multi-mode approach has also been used to achieve efficient use of resources; for instance, dynamic resource allocation techniques, such as adaptive servers [1], [2], [8], [9], have been developed for this purpose.…”

Abstract-Among the key characteristics of cyber-physical systems are the ability to adapt to changes during operation, the multidimensional complexity of multi-functionality and the underlying heterogeneous distributed architecture, as well as resource use efficiency. In this paper, we propose a compositional multi-modal approach to modeling, analyzing, and designing such systems. We introduce a general framework for modeling and compositional analysis of multi-mode systems on a distributed architecture that facilitates adaptivity, efficient use of resources, and incremental integration. We present some preliminary results, and we describe some of the remaining challenges and future directions.

One goal of research activities is finding ways to manage the growing complexity of embedded systems using selfconfiguration methods. While autonomous configuration could potentially be used in safety-critical and real-time systems, the basic requirements are not yet in place. This paper will outline a concept for the real autonomous configuration of TDMA-based communication processes, which currently does not exist.The paper initially addresses the TDMA-specific framework conditions and a potential solution. The issue of the mandatory a-priori known schedule is resolved using a generic schedule, because a simple method based on "free-slot-reserved-forfurther-nodes" is not feasible. The most difficult part -the startup -was implemented through the generic schedule and an ID-based collision resolution process. To demonstrate the viability of the concept, the configuration method was implemented using a FlexRay communication system. This also satisfied the goal of eliminating the need for additional hardware and preserving the fault tolerant multimaster structure of the FlexRay system. The functionality of the concept was validated under different scenarios. The configuration times were analyzed, the results of which are also detailed here.
