OBJECTIVES:

To learn and know about the embedded system concepts.

To study the architecture of various embedded controllers. To learn the software programming concepts in embedded system design. To study and familiarize real time operating system concepts. To learn and understand embedded system design processes.OUTCOMES:

Learners should be able to: explain and identify the embedded systems applications. select and compare dierent architectures for suitable applications. apply software programming concepts in embedded system applications. apply real time operating system concepts in real time applications. design and optimize embedded system design process for real time applications.
