Embedded System can be thought of as a computer ...... system having
..... embedded in it

..... is at the heart of the product that is
generally designed to carry out computation for real–time
operations and it is designed to perform a specific task within a complete device including hardware and mechanical parts

Embedded systems are built as a microcontroller or a
microprocessor based system

.... is the process of embedding hundreds of
thousands of electronic transistors into a chip

... circuits are commonly used components in
Embedded systems.

.... is a term that describes the complexity of an integrated circuit.

Embedded System .... has the elements such as input/output interfaces,
memory, user interface and the display unit

Hardware of the embedded system is assembled with
a microprocessor/microcontroller

To load the internal control programs and their
data during execution

To supply the electrical power required for
operating the inner circuits.

To execute the instructions of the control program
in sequence.

Used by the controller to measure or specify the
execution times of internal parts of the running
application and the operating system

To link the controller with the other parts of the system
and to send outputs to the outside world

..... is an example of Input devices

It measures the physical quantity and converts it to an
electrical signal

sensor compares the output given by the D–A Converter
to the actual (expected) output stored in it and stores the
approved output signal

A–D Converter:
An analog–to–digital converter circuit that converts the
analog signal sent by the ...... into a digital signal.

A digital–to–analog converter converts the digital data fed by
the .... to analog data.

To link the controller with the other parts of the system and to
get inputs from the outside world
