1. Introduction (1/7)
1.1 Application areas and examples Cyber-Physical Systems (CPSs) are characterized by integrating
computation and physical processes. Diagrammatic layout for CPSs

1. Introduction (3/7)
1.2 Common characteristics Cyber-physical systems must be dependable.
Dependability encompasses the following aspects of a system: Reliability Maintainability Availability Safety Security
Embedded system must be efficient. Energy Run-time efficiency Code size Weight Cost
Embedded systems are connected to the physical environment through sensors collecting information about that environment and actuators controlling that environment.

1. Introduction (4/7)
Many cyber-physical systems must meet real-time constraints. Typically, embedded systems are reactive systems. Many embedded systems are hybrid systems in the scene that they
include analog and digital parts. Most embedded systems do not use keyboards, mice and large com-
puter monitors for their user-interface. These systems are frequently dedicated towards a certain applica-
tion.

1. Introduction (5/7)
1.3 Challenges in Embedded System Design Many additional design goals must be taken into account.
Embedded systems really must be dependable. Due to efficiency targets, software designs cannot be done independently
of the underlying hardware. Embedded systems must meet many non-functional requirements such as
real-time constraints, energy/power efficiency and dependability require-ments.
The link to physics has additional implications. Real systems are profoundly concurrent. Real embedded systems are complex. Traditional sequential programming languages are not the best way to de-
scribe concurrent, timed systems.
