3. Definitions and Terminologies

4. Internet of Things
The Internet of Things (or IoT for short) refers
to uniquely identifiable objects and their virtual
representations in an Internet-like structure

5. Ubiquitous Computing
"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.

6. Ubiquitous Computing
 Ubiquitous computing is roughly the opposite of
virtual reality.
 Where virtual reality puts people inside a computergenerated 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.

7. Semantic Web

14. Embedded System Definition
Embedded System is specifically
designed for a particular function and to
perform a few tasks in the most efficient
way.

15. 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.

16. Embedded System Definition
Simply Embedded systems is invisible

32. Embedded System Design
 Modeling via any modeling language (System C or
even Matlab)
 HW/SW partitioning (Determine which blocks must be H/W &
which may be S/W)
 Global Design of the S/W part
 Unit Design of the S/W part

33. Embedded System Design
Challenges
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 ?

34. Embedded System Design
Challenges
 How do we minimize power ?
-Turn off unnecessary logic
-Reduce memory accesses
-Use sleep modes in unused controllers

35. Embedded System Design
