EMBEDDED SYSTEMS & ITS APPLICATIONS Special Lecture by Prof. Dr.N.SHANMUGASUNDARAM Professor & Head – ECE Department Sri Eshwar College of Engineering 22-Feb-19 NSS / SECE

Introduction to Embedded System 22-Feb-19 NSS / SECE

Smart Applications Software Hardware + = What is Embedded System? DRIVES = Embedded system is a Hardware with Software embedded in it, for a dedicated application. 22-Feb-19 NSS / SECE

Why Embedded system? There are Environments where the general purpose computers do not really get into action. For example: AC has a temperature control sub-system It is not viable to use a PC’s there for achieving Temperature control. 22-Feb-19 NSS / SECE

Redefining - Embedded System Embedded system is a Microcontroller based hardware Software driven Real time control system Autonomous or Human interactive Reliable system Operate in diverse environments 22-Feb-19 NSS / SECE
