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

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.
