Embedded Systems
A sneak peek…
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.
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.
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.
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
