Embedded Systems

• A sneak peek

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
