INTRODUCTION TO EMBEDDED SYSTEM
EMBEDDED SYSTEM
An embedded system is a special-purpose computer system
designed to perform one or a few dedicated functions, sometimes
with real-time computing constraints. It is usually embedded as part
of a complete device including hardware and mechanical parts. In
contrast, a general-purpose computer, such as a personal computer,
can do many different tasks depending on programming. Embedded
systems have become very important today as they control many of
the common devices we use.
APPLICATIONS OF EMBEDDED SYSTEM
We are living in the Embedded World. You are surrounded
with many embedded products and your daily life largely depends
on the proper functioning of these gadgets. Television, Radio, CD
player of your living room, Washing Machine or Microwave Oven in
your kitchen, Card readers, Access Controllers, Palm devices of your
work space enable you to do many of your tasks very effectively.
Apart from all these, many controllers embedded in your car take
care of car operations between the bumpers and most of the times
you tend to ignore all these controllers.
Military and aerospace software applications
From in-orbit embedded systems to jumbo jets to vital battlefield
networks, designers of mission-critical aerospace and defense
systems requiring real-time performance, scalability, and highavailability
facilities consistently turn to the LynxOS® RTOS and the
LynxOS-178 RTOS for software certification to DO-178B.
Communications applications
"Five-nines" availability, CompactPCI hot swap support, and hard
real-time response—LynxOS delivers on these key requirements and
more for today's carrier-class systems. Scalable kernel
configurations, distributed computing capabilities, integrated
communications stacks, and fault-management facilities make
LynxOS the ideal choice for companies looking for a single operating
system for all embedded telecommunications applications—from
complex central controllers to simple line/trunk cards.
