What is special about embedded systems? slide from IST meeting about ES Brussels, 22/10 are tightly coupled to the physical world are surrounded by physical processes are highly resource constrained will have to last for a long period of time interoperability becomes a major issue user interface needs to be very simple or none are subject to high or extremely high assurance requirements

Relation dependability - embedded systems tightly coupled to physical world surrounded by physical processes interoperability becomes a major issue adds complexity adds unpredictability physical world asks for dependable device drivers, dependable OS interoperability asks for dependable networking and communication relates to CT mobile computing & wireless communication relates to CT critical infrastructures interdependencies

Relation dependability - embedded systems are highly resource constrained correctness depends a.o. on non-functional: time (cpu), memory, bandwidth, QoS, size, energy, heat asks for consolidation of existing work around time real-time modeling and design real-time OS asks for integration of existing work into general dependability work asks for new research some non-functional aspects received little attention in past integration of all non-functional aspects extra dimension of CT proactive computing

Relation dependability - embedded systems will have to last for a long period of time are subject to high assurance requirements relates to all Dependability Technologies asks for reorganization for self-repair and recovery relates to CT proactive systems (only proactive systems can last a long period of time)

extra elements ubiquitous computing, ambient intelligence, pervasive computing, mobile and other networks most of these are embedded systems ! evolving sw, adaptable sw, reconfigurable sw relates to CT proactive computing time to market, costs, reuse component based development generating code: tools, models

Embedded Systems: strategic for Europe for every PC: about 50 ES PC-market has reached plateau, ES market expected to grow for many more years importance for Europe US has large share of ‘packaged software’ market for PC sw written in Europe: often for ES competitiveness of Europe’s industry industry depends increasingly on embedded computing embedded computing is at the hart of differentiation of products

Embedded systems: challenges slide from IST meeting about ES Brussels, 22/10 requirements reduce costs reduce time to market optimal quality system-centric approach global design view including hw, sw and the environment economic, trade off between cost and quality multidisciplinary skills in hw, sw, control and networks raises non-trivial research problems such as unified computation and interaction model build systems correct by construction build robust, reconfigurable intelligent systems
