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.

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