Embedded systems combine both hardware and software to form an integral part of a larger system or machine. They are designed to perform specific tasks, such as controlling an engine or processing signals in real time, without human intervention. Examples include processors in cars, robots, televisions, and consumer electronics. Embedded systems have a long design life cycle that involves acquiring components, testing and certifying the system, planning logistics and repairs, and potentially upgrading the system over time. Many embedded systems now also connect to the internet, allowing consumer products and industrial equipment to access online services. Common application areas of embedded systems include the military, automotive, medical, telecommunications, consumer, and industrial sectors.

3. INTRODUCTION
 Over the past decade, there has been a steady
increase in the number of applications that demand
customized computer systems that offer high
performance at low cost.
 These applications are, more often than
not, characterized by the need to process large
amounts of data in real time.
 Examples include consumer electronics, scientific
computing, and signal processing systems. Constraints
on performance, cost and power make software

5.  Definition for: Embedded System
 A combination of hardware and software
which together form a component of a larger
machine.
 An example of an embedded system is a
microprocessor that controls an automobile
engine.
 An embedded system is designed to run on
its own without human intervention, and may
be required to respond to events in real time.

6. EMBEDDED SYSTEMS : THE
DESIGN
 A system can be defined as a group of devices or
artificial objects or an organization forming a network
especially for distributing something or serving a
common purpose .
 To embed a system into some object means to make
that system an integral part of the object.
 Examples include DSP processors in hand-held
communication devices, programmable controllers
installed in robots or cars, and video signal processors
in television sets.

CYCLE

8. Component acquisition
 Because an embedded system may
be more application-driven than a
typical technology-driven desktop
computer design, there may be more
leeway in component selection.

9. System certification
 Embedded computers can affect the safety
as well as the performance the system.
 Therefore, rigorous qualification procedures
are necessary in some systems after any
design change in order to assess and reduce
the risk of malfunction or unanticipated sys
system failure.

10. Logistics and repair
 Whenever an embedded computer design is
created or changed,
 it affects the downstream maintenance of the
product.
 A failure of the computer can cause the
entire system to be unusable until the
computer is repaired.

11. Upgrades
 Because of the long life of many embedded
systems, upgrades to electronic
components and software may be used to
update functionality and extend the life of
the embedded system with respect to
competing with replacement equipment.

12. EMBEDDED INTERNET:
 Used in everything from consumer electronics to
industrial equipment, embedded systems —
small, specialized computer systems stored on a single
microprocessor — are playing a major role in the
growth of the Internet and the boom of wireless
communication channels.
 Due in part to embedded systems, more and more
consumer products and industrial equipment are
becoming Internet-friendly.
