What are Embedded Systems?
Unlike most other concepts or terms in engineering; Embedded
Systems as a term is a little difficult to define. The difficulty is not in
getting a grasp of the concept per se,
but in getting a perspective on the number of tools and products which use Embedded
Systems.
A quick look at the micro and macro elements of a software device
should serve as a good starting point for our understanding of Embedded Systems.
Whenever you come across a device, have you wondered the nuts and bolts of it
–that is, the innumerable parts that go into it? If it is a smartphone that we
are thinking about, how many of us lay users have given a thought to the parts
that coordinate and synchronize with each other to make the product functional?
These could be both the hardware and the software that go into the device. This
is what may be summarized as Embedded Systems.
A myriad of applications
Embedded Systems can consist of many applications, what are these?
When talking about Embedded Systems, one
could think of anything among these: alarm
systems, answering machines, camcorders, calculators, automated teller machines, cell phones, copiers, digital cameras, fax machines, home security systems, scanners, printers, portable video games, personal digital assistants, microwave ovens, lighting systems, washing machines, and many parts of automobiles, such as transmission
control and cruise control, fuel injection, anti-lock brakes, or active
suspension. All these devices use Embedded Systems.
