Note publique d'information : Embedded systems now include a very large proportion of the advanced products designed
in the world, spanning transport (avionics, space, automotive, trains), electrical
and electronic appliances (cameras, toys, televisions, home appliances, audio systems,
and cellular phones), process control (energy production and distribution, factory
automation and optimization), telecommunications (satellites, mobile phones and telecom
networks), and security (e-commerce, smart cards), etc. The extensive and increasing
use of embedded systems and their integration in everyday products marks a significant
evolution in information science and technology. We expect that within a short timeframe
embedded systems will be a part of nearly all equipment designed or manufactured in
Europe, the USA, and Asia. There is now a strategic shift in emphasis for embedded
systems designers: from simply achieving feasibility, to achieving optimality. Optimal
design of embedded systems means targeting a given market segment at the lowest cost
and delivery time possible. Optimality implies seamless integration with the physical
and electronic environment while respecting real-world constraints such as hard deadlines,
reliability, availability, robustness, power consumption, and cost. In our view, optimality
can only be achieved through the emergence of embedded systems as a discipline in
its own right.
