EMBEDDED SYSTEM

2. 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

3. 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

4. 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

5. 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)

6. 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

7. 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

8. 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
