Topics to be Discussed

3. 
 Arrangement of units according to set of rules.
 A way of working or doing one or many tasks
according to a fixed plan.
 For example: -
A watch is a time displaying
system.
System

4. 
 Embedded means something that is attached to another
thing.
 A computer hardware having software embedded in it.
 It can be an independent or a part of a large system.
 A μP based system designed to perform a specific task.
 For example: -
A fire alarm which will sense
only smoke.
Embedded System

5. 
 It has hardware.
 It has application software.
 It has Real Time Operating system
(RTOS).
Architecture

6. 
Classification
Medium ScaleSmall Scale Sophisticated

7. 
 Single Functioned
 Tightly Constrained
 Reactive and Real Time
 Microprocessors Based
 Memory
 Connected
 HW-SW Systems
Characteristics

8.  Serial Communication Interfaces (SCI): RS-232, RS-422, RS-485,
etc.
 Synchronous Serial Communication Interface: I2C, SPI, SSC
and ESSI (Enhanced Synchronous Serial Interface).
 Universal Serial Bus (USB)
 Multi Media Cards: SD cards, Compact Flash, etc.
 Networks: Ethernet, Lon Works, etc.
 Fieldbuses: CAN-Bus, LIN-Bus, PROFIBUS, etc.
 Timers: PLL(s), Capture/Compare and Time Processing Units.
 Discrete IO: aka General Purpose Input/output (GPIO).
 ADC/DAC: Analog to Digital/Digital to Analog.
 Debugging: JTAG, ISP, ICSP, BDM Port, BITP, and DB9 ports.
Peripherals

9. 
Small Size
Reduced cost
Portability
Low power operation
Real time response
Advantages

10. 
High development effort.
Hard to move from one machine to another.
Hard to take backup of files.
Larger time to market.
Disadvantages

11. 
Applications

12. 
 Computer integrated into another system is embedded
system.
 It is a part of a bigger system.
 Programming with resource constraints.
 Hardware chip programmed for a particular task
results.
 More capable, powerful and complex chip designs are
growing.
 This is illustrated by new design approaches such as
multi-core technologies.
Conclusion

13. 
New h/w changes are coming up.
New devices are being designed.
More sensors are incorporated in our lives.
The domain names will change, like Smart
Homes, Smart Cities or IoT ( Internet of Things).
All above concepts are same and that is
embedded systems concepts.
