The Advantages of an Embedded System
An embedded system is a type of computer that is only designed to
perform specific tasks and is difficult if not impossible to reprogram.
Some of the earliest computers were what we now think of as an embedded
system, as they only did one task, such as solving a particular puzzle.
However, today an embedded system earns its name from the fact that it
is found within another machine.
Physical Benefits
Because
an Embedded System Training in Jaipur always performs the same basic tasks, it rarely
needs any hardware changes such as adding extra memory or storage space.
In turn, there's usually little need for people to be able to
physically access the system. As a result, it's much easier to house an
embedded system in a device such as a set-top box that isn't designed
for user servicing.
Dedicated Tasks
Unlike
a full-blown computer, an embedded task usually only performs one task
at a time. For example, a cable box might have the task of taking the
input signal from the cable, tuning to a specific channel and outputting
the signal in a format that a television set can understand. By being
dedicated to this task, the box can do it without interruption. In many
contexts operating continuously may be critical; for example, a set-top
box has to continuously process the picture to ensure there are no
onscreen glitches.
Operating System
As
an embedded system usually performs a simple role that does not change,
the requirements for the operating system are less onerous. Often an
embedded system can run and older or less sophisticated operating system
and won't need updating. For examples, devices ranging from ATMs to
airplane seat-back entertainment displays were able to run a special
version of Windows XP for years without any problems developing until
Microsoft began to withdraw support for the system.
Specifications & Costs
Hardware
demands for embedded systems are usually much lower than those for full
PCs. For example, concentrating on a single task means multi-core
processors aren't usually needed. Depending on the purpose of the
system, it may be able to work with slow processors because there's no
need to allow excess capacity for the possibility of more demanding
tasks such as video processing. In turn, these reduced specification
requirements can substantially reduce costs.
