2.  Children need Embedded systems to play smart
video games and to operate automatic chocolate
vending machines!!
 Young people need embedded system to borrows
smart cards from parents to see movies!!
 House wives need for home appliances like
microwaves,t.v,music systems & so on
 Organizations requires E.s for network systems &
products.
 There are uncountable examples of applications of
embedded systems.

3. An overview.
Examples.
Characteristics.
General Requirements.
Embedded System Design.
Key Properties of
Embedded Software Systems
Application Areas.
Conclusion.

4. What is an Embedded Systems.
History of Embedded Computing.

5. An Embedded Systems is combination of
computer hardware and software and
additional mechanical or parts, designed to
perform a specific function.

6.  Late 1940’s: MIT Whirlwind computer was
designed for real-time operations.
 Late 40’s: Computers to control chemical processes.
 First microprocessor was Intel 4004 in early
1970’s, designed for a calculator.

7. EMBEDDED SYSTEM DEVICES
On-Body Ad-hoc Sensor Adaptive Wireless In-Home
In-body
MEMS Sensors
Closed loop control
Neuro-stimulators

8. output analog

9.  Sophisticated functionality.
 Real-time operation, meet deadlines.
 Costs .
 Power and Security.

10. Real-time systems process events.
Events occurring on external inputs cause other
events to occur as outputs.
Minimizing response time is usually a primary
objective, or otherwise the entire system may fail to
operate properly.

11. Hardware Requirements
Software Requirements
E.S=H/W+S/W+other functional parts.

12. Micro Processor
Input devices
Output devices
Timer module
Memory modules
System buses

13. Operating Systems
Programming languages C,C++ and alp

14. Embedded System Design
 Software doesn’t do anything without
hardware.
 Hardware is the lens through which we
view software characteristics.
 Software executes on a hardware platform.

15.  There are many different CPU architectures used in
embedded systems designs.
 This in contrast to the desktop computer market, which
as of this writing (2003) is limited to just a few
competing architectures, chiefly
 intel’s X86 &
 Apple
 Motorola
 IBM Power pc
used in the Apple Macintosh.

16. Integral with physical processes
Reactive
Heterogeneous

18. Application Areas

19.  Automatic Teller Machines or ATM's.
 Automobile Engine Management Computers.
 Business machines (for example FAX
machines).
 Consumer electronics.
 Control Systems (manufacturing,, electric
power).
 Communications infrastructure (for example,
financial data).
 Energy Infrastructure (oil, gas and electric
utilities).

20. Conclusion
Embedded Systems has become a vital component of
almost every larger system. Almost every household has one, and
tens of millions of them are use every day. It seems inevitable
that the number of embedded systems will continue to increase
rapidly. If an embedded system is designed well, the existence of
the processor of the processor and software could be completely
unnoticed by a user of the device.
