2. Introduction To Embedded System:
• Embedded systems are combination of hardware and software systems
with a dedicated function within a mechanical or electrical system.
• It is either fixed in capability or is programmable to perform a special
function.
• Programming interfaces are provided to Embedded Systems that are
programmable.
3. Domains Required In Embedded:
The prerequisites domains which are
required to learn embedded systems are:
• Knowledge of digital Electronics.
• Concepts of Basic Electronics should
be clear.
• Knowledge of Microprocessors.
• C programming should be known.
4. History of Embedded Systems:
• 1970: Commercial use of computers began, microprocessors were also
available. Hence the race for Miniature circuits began.
• 1980: Unification of Computers and Telecommunication was done by the
availability of the computer networks.
• 1990: The concept of “Information Technology” began. It allowed
widespread access to WWW (World Wide Web) and the internet.
• 2000: Second parallel Evolution begins for the embedded systems.
5. Advantages Of Embedded Systems:
• Physical Benefits: Because an
embedded system always performs
the same basic tasks, it rarely needs
any hardware changes such as adding
extra memory or storage space.
• Specifications & Costs:
Hardware demands for embedded
systems are usually much lower than
those for full PCs.
6. Scope of Embedded System:
Skilled graduates in this industry can
find jobs in the following sectors:
• Consumer Electronics.
• Product Development.
• Aerospace.
• Telecommunications.
