2. Introduction to Embedded Systems
• Embedded System is a combination of Software and
Hardware which is embedded in large electronic
systems.
• All computing systems other than general purpose
computer falls under the category of Embedded
Systems.
3. Elements of Embedded Systems
• Hardware
So that other devices can be connected. For e.g.
processor, I/O devices, memories etc.
• Main application Software
To run the programming codes designed as per the
project.
• Real Time Operating System(RTOS)
To supervise the working of main application software.
4. Embedded Systems vs. Microcontrollers
• A microcontroller is an electronics device that has an
inbuilt processor, memory and peripherals. It can be
used as an embedded system.
• Most of the microcontrollers that we use today, are
embedded or placed in other electronic systems.
5. Classification of Embedded System
• Small Scale
uses 8 to 16 bit microcontroller
• Medium Scale
uses 16 to 32 bit microcontroller
• Sophisticated Scale
uses more than 32 bit microcontroller
6. Embedded Systems around You
