Software tools and MethodsIterative Design Processfor Self-Describing Real-TimeEmbedded Software ComponentsON GOINGPROJECTDevelopment of a design method for self-adaptive systems that are built out of components.In order to integrate the latter into a (possibly already running) system, thecomponents need to describe their needs in terms of functional and non-functional requirements(self-descriptive components). Whereas the approach is domain independent,the main application area is the automotive domain (key domain of partnerFraunhofer ESK).◗ During design, we need to evaluate resource consumption of system parts and optimizethe estimation of overall system resource requirements.◗ During runtime, want to adapt resource allocation depending of estimated resourceconsumption and safety criteria, discover environmental changes or discover/use servicesthat appear dynamically.TECHNOLOGICAL OR SCIENTIFIC INNOVATIONSThe complexity of upcoming embedded systems can not be managed by traditional methods,as studied in the automotive domain, as exemplary application area. Self-adaptivesystems and self-organization paradigms are promising approaches to tackle arisingchallenges. But no suitable design methodology for self-adaptive systems allowing designand evaluation of self-adaptivebehavior exist: Today’s systems aredeveloped statically at design timeand lack the ability to describe theirstructure and status at runtime.This is inevitable information forself-adaptive systems enablingthese to identify the context andadapt adequately. This systemadaptability needs to be well defined,especially in real-time embeddedsystems which imposetiming and resource constraints onthe system behavior which must inparticular be meet during the adaptationprocess.STATUS - MAIN PROJECT OUTCOMESCONTACTAnsgar RADERMACHERCEA LIST/LISE+33 (0)1 69 08 38 12ansgar.radermacher@cea.frPARTNERSResearch institutes, universities:CEA, FRAUNHOFER ESK,MUNICHPROJECT DATACoordinator:FRAUNHOFER - CEACall:ANRStart date:September 2009Duration:36 monthsGlobal budget (M2):0.6 (CEA)1.2 (CEA+Fraunh.)Funding (M2):0.3 (CEA)0.8 (CEA+Fraunh.)◗ The project has been presented at the PICF (Programme Inter Carnot Fraunhofer)event end of November 2009, at the Systematic workshop in December 2010 and at the3rd workshop on adaptive and reconfigurable embedded systems (APRES 2011).◗ Major use cases, a first meta-model for self-X information and an initial tool-chainsupporting self-X aware applications have been defined.Automotive & Transports WG43
