DEFINITION OF EMBEDDED SYSTEMS

Embedded Systems are the Microprocessor /
Microcontroller based computing/control systems which
are designed for specific task. Ex-Automatic Washing
Machines, Robots, Electronic Cash Register, Mobile
Phones etc. Every Device is converting into automotive,
there is the role of Embedded Technology.

Market Share of Embedded Tech.
In comparison to IT industry ,this
domain is stable while slowly
increased to present 40%
software market. Many IT MNC
are dealing with Embedded
software, thus creating the need
for skilled Engineers who are
competitive enough to
understand product’s market &
design requirements .So knowing
basic development environment
& platform increases the chances
for a good start up with
development Firms.


 Benefits of Embedded Systems
1. Minimization Of Circuit.
2. Reliable
3. Power Efficient
4. Production when done even on Medium-scale
is cost effective.
5. Product customization even after production is
possible to a limit.


Microprocessors
CPU for Computers
No RAM, ROM, I/O on CPU chip itself
Example：Intel’s x86, Motorola’s 680x0

Data Bus

CPU RAM ROM I/O port Timer Serial COM Port

General-Purpose
Micro-processor

Many chips on mother’s board
Address Bus

General-Purpose Microprocessor System

Microcontrollers


Microprocessor vs. Microcontroller
Microprocessor  Microcontroller

Contains only CPU; RAM, • CPU, RAM, ROM, I/O and
ROM, I/O, timer are separately timer are all on a single chip
interfaced.

• Fix amount of on-chip ROM,
Designer decides on the amount
of ROM, RAM and I/O ports. RAM, I/O ports

Expansive • For applications in which cost,
power and space are critical
General-purpose • Single purpose


Micro Controller Examples
