Topics
Definitions and Terminologies
The Internet of Things (or IoT for short) refers to uniquely identifiable objects and their virtual
representations in an Internet-like structure
Internet of Things
"Ubiquitous computing names the third wave in computing, just now beginning.
First were mainframes, then the personal computing era, person and machine staring uneasily at each other
across the desktop.
Now comes ubiquitous computing, or the age of calm technology, when technology recedes into the background of our lives." --Mark Weiser- 1988.
Ubiquitous Computing
Ubiquitous computing is roughly the opposite of virtual reality.
Where virtual reality puts people inside a computer-generated world, ubiquitous computing forces the computer to live out here in the world with people.
The initial incarnation of ubiquitous computing was in the form of "tabs", "pads", and "boards" built at Xerox PARC, 1988-1994.

Embedded System is specifically
designed for a particular function and to
perform a few tasks in the most efficient way.
Embedded System Definition
Embedded System Definition
Historically, the term embedded systems was
used to describe any non-PC-related system, but
in time, the definition has grown to include any
system that is dedicated to a particular
functionality.
Simply Embedded systems is invisible computer

Embedded System Design
For a certain application
Which functional blocks should be performed in Hardware?
Which functional blocks should be performed in software?
How do we meet our deadline ?
Faster Hardware or Cleverer Software ?
Embedded System Design Challenges
How do we minimize power ?
-Turn off unnecessary logic
-Reduce memory accesses
-Use sleep modes in unused controllers
Embedded System Design Challenges
Cheaper
Highly configurable
Easier in versions updates
Shorter development cycle
Must be logically and temporally correct
Constrained with processor speed which may satisfy real time application and may not.
