This document discusses embedded systems and provides information on: - The components of an embedded system including a processor, peripherals, and software. - Major application areas such as consumer electronics, automation, and networking. - The embedded system design process including determining requirements, designing architecture, selecting hardware and software, and testing. - Recent trends in embedded systems including reduced size, cost and power consumption.

3.  To Introduce embedded system.
 To introduce embedded system design
process.
 Discuss the recent trends.
 Major application areas.

4.  It can be described as one consisting a
processor, associated peripherals, and
software used for a specific purpose.
 It performs a well defined task (in contrast
with desktop PC’s)

3. Drivers (For driving heavy loads).

9. It is a program written in
any programming
language, which controls
the operation of the total
system.

10. Determine the requirements
Design the system

platform
Code the application
And optimize
Verify the software
On the host system
Verify the software
On the target system

11.  Functional and non-functional.
 Multi function or Multi mode system.
 Size, cost, Weight etc.
 Selecting the H/W components.
 Application specific H/W.
 External interfaces.
 Input devices.
 Output devices.

12. System architecture depends on,
 Whether the system is real time.
 Whether OS needs to be embedded.
 Size, Cost, Power consumption etc.

13. If OS needed we can select,
 Real time OS (such as RTLinux,Vx Works,
VRTX, pSOS, QNX etc.).
 Non-real time OS ( such as Windows CE,
embedded Windows XP etc).

14. We can select any one of the following,
 Microprocessor
8085,8086,Pentium
 Microcontroller
MCS-51,PIC,AVR,MSP430
 Digital Signal Processor
dsPIC,Blackfin,Sharc,TigerSharc

15.  The hardware platform.
 The operating system.
 The programming language.
 The development tools.

16.  Choice of language.
 Assembly.
 C language.
 Object Oriented Languages
(C++, Java etc.).
• Optimizing the code

17.  Compile and assemble
the source code into
object file.
 Use a simulator to
simulate the working of
the system.

18.  Download the program
using a programmer
device.
 Use an EMULATOR or
on chip debugging tools
to verify the software.

19.  Due to the developments in Micro electronics availability
of processors increased.
 Reduces cost.
 Increased speed.
 Reduce Size
 Reduce Power.
