9. Introduction: System Definition
The way of performing one or several tasks according to a fixed set of rules, program or plan. OR
An arrangement in which all units assemble and work together according to a program or plan.
e.g. A microwave oven, A watch, A washing machine etc.

10. Embedded System Definitions
A system, dedicated for an application, that has computer hardware with software embedded in it as an one of its most important components.
An embedded system is one that has a dedicated purpose software embedded in a computer hardware.
It is a dedicated computer based system for an application(s) or product. It may be an independent system or a part of large system. Its software usually embeds into a ROM or flash.
“It is any device that includes a programmable computer but is not itself intended to be a general purpose computer”, Wayne Wolf.

11. Computer System Components
A microprocessor
Memory: Primary (RAM, ROM, Cache), Secondary (Magnetic memory: Hard disk, diskettes, Tapes and Optical memory: CD-ROM)
Input units: Keyboard, mouse, scanner etc.
Output units: Video monitor, printer etc.
Networking units: Ethernet card etc.
I/O units: Modem, fax etc.
Etc.

12. Embedded System Components
It has three main components
It has hardware
It has main application software
It has real time operating system (RTOS)

13. Hardware Components

14. Classification of Embedded Systems
Small Scale Embedded Systems: - Single 8/16 bit microcontrollers, - little hardware and software complexities
Medium Scale Embedded Systems: -Single or few 16/32 bit microcontrollers or DSPs or RISCs, - have hardware and software complexities
Sophisticated Embedded System: -Scalable processors or configurable processors and PLAs, -enormous hardware and software complexities

15. Processor in the System
Processor is the heart of the embedded system
Embedded System Processors
GPP: Microprocessor, Microcontrollers, Embedded Processor, DSP, Media Processor
Application Specific System Processor(ASSP)
Mutiprocessor system
GPP Core(s) or ASIP Core(s) integrated in ASIC or VLSI.

16. Other Hardware Units Power Sources
