It is estimated that each year embedded software is written five times as much as 'regular' software
The vast majority of CPU-chips produced world-wide today are used in the embedded market ... only a small portion of CPU's is applied in PC's
... the number of software-constructors of Embedded Systems will rise from 2 million in 1994 to 10 million in 2010;
... the number of constructors employed by software-producers 'merely' rises from 0.6 million to 1.1 million

Importance of Embedded Systems
Most of the functionality of Embedded Systems will be implemented in software!
Some problems
How can we capture the required behaviour of complex systems?
How do we validate specifications?
How do we translate specifications efficiently into implementation?
Do software engineers ever consider electrical power?
How can we check that we meet real-time constraints?
How do we validate embedded real-time software? (large volumes of data, testing may be safety-critical)
Connecting embedded devices will extend the scalability limits of today’s systems even beyond the Internet’s global scale. One user can have hundreds and thousands of embedded devices, disrupting traditional networking and, in particular, addressing techniques. Furthermore, it would not be possible or economically viable to connect all these devices by traditional wired technologies; therefore, wireless will become an attractive alternative, opening up new research and development areas.
What are the other long-term trends and impacts of this technology turn? What other implications does it pose to the current computer science and technology? This and other questions are addressed by six renowned researchers in this field.

One owner can have hundreds and also thousands of embedded devices, disrupting traditional networking and additionally, specifically, addressing techniques. Furthermore, it wouldn't be a possibility or economically viable to connect these equipment by traditional wired technologies; subsequently, wi-fi can become a good attractive alternative, opening up brand new studies and also development areas.automateandvalidate
