In the recent technical
world, embedded technology has been a matter of discussion these days. When it
comes to career and studies, embedded technology has great benefits. Many
engineering projects, modern appliances, and sophisticated electronic systems
use some kind of embedded systems, which increases its importance. All the
embedded systems consist of two parts: the hardware and the software. The
software part can be used to control the hardware and do the required task.
Embedded systems are used in
several devices such as automobiles, traffic lights, cameras, wireless network
routers, mp3 audio players, and so on. It is an important subject for
electrical engineering students, as it is a part of every undergraduate-level
courses. One or two courses in electrical engineering definitely contain
embedded systems.
A
Brief History of Embedded Systems
Some scientists claim that
the first embedded system was used in Apollo missions, i.e. Apollo 7, which
landed on the moon in 1969. Since then engineers began using it in some other
devices as well. After a couple of years, Intel launched a microprocessor which
was powerful enough to control any embedded system. It was during the 80’s that
embedded systems saw a dramatic evolution. There were great improvements in
terms of memory capacity, operating systems, performance, software development
tools such as compilers, and so on.
Today, embedded systems are
used in the aeronautics industry, sophisticated electronic appliances, military
applications, robotics, and various means to enhance people’s standard of
living in every possible way.
Benefits
of Embedded Systems
As mentioned before, embedded
systems can be used in a variety of applications. Multimedia products such as
smart phones, printers, video-game consoles, home entertainment systems,
washing machines, refrigerators, microwave ovens, refrigerators, blue ray
players, televisions, air conditioners and digital cameras use some type of
embedded systems. These appliances are used to upgrade human lifestyle. In
fact, today we cannot imagine a life without them. Embedded systems have become
an integral part of our lives.
Apart from usage in
day-to-day appliances, embedded systems are used in automobiles to produce
high-end electric motors. As a result, this technology gave birth to automotive
safety systems such as electronic fuel injection systems, anti-lock braking
systems and the most popular, Global Positioning Systems (GPS).
On the other hand, there are
applications in medical science as well. Pieces of equipment like MRI scanners,
heartbeat and blood pressure monitors, ECG, etc. utilise embedded systems.
Today, most of the applications run with
artificial intelligence (AI) technology and it would not be possible without
embedded systems. Emerging engineers in this technology have undoubtedly a
bright future. However, perseverance and hunger for knowledge can establish you
as an ardent embedded systems engineer.
