A microprocessor is a single VLSI chip having a CPU

A .... is a single–chip VLSI unit

is also called as microcomputer

Single task oriented

RAM,ROM, I/O ports, Timers can be added externally and can vary in numbers

.... is cheaper than ....

.... consumes less power & space

Enbedded System software is normally written in a high–level language and then compiled
down to offer code that can be mounted within a volatile memory in the hardware.

The software should consider three limits which are system
memory, processor speed, and power consumption

Use of ...... has some
distinct advantages over ........ codes–low
development time, shorter debug cycles and ease of maintenance

In Mix mode programming, both the “C” & “C#”
language are used for application development.

RTOS supervises the application software and provide
mechanism to let the processor run a process as per
scheduling by following a plan to control the latencies.

RTOS sets the rules during the execution of application
program.
and It is responsible for managing the different hardware resources of Embedded system

we can classify embedded systems as real time, stand alone, networked, mobile based on

we can classify embedded systems as small, medium, sophisticated scale based on

Infrequent deadline misses are acceptable, but may degrade the
system’s quality of service

Can miss some deadlines, but eventually performance will degrade
if too many are missed, such as sound system in your computer

Must absolutely hit every deadline, such as nuclear, some medical
and defense applications

takes the input
from the input ports either analog or digital and
processes, calculates and converts the data and gives the resulting data through the connected devices

are related to a network to
access the resources
