At present, you can see that we are completely encircled by computing systems. Millions of computing systems are prepared and scheduled for desktop computers (like Personal Computers, mainframes, workstations, and servers) but incredibly, billions of computing systems are prepared every year immersed within larger electronics gadgets and most of the computing systems are unnoticed.

Now, embedded systems are explored in digital cameras, cell phones, camcorders, calculators, portable video games, microwave ovens, personal digital assistants, answering machines, washing machines, home security systems, lighting systems, copiers, fax machines, scanners and printers, alarm systems, cash registers, automated teller machines, cruise control, transmission control, fuel injection, active suspension, and anti-lock brakes and many other gadgets or devices.

What is an Embedded System?

An exact definition of embedded system is not easy to say but simply stated that all types of computing systems or general purpose computer (with the keyboard, monitor, and many more) are embedded systems.
Basically, a system is a suitable way of organizing, working or performing one or more tasks according to a stable set of rules, plan or program and also says as that an arrangement in which all units work together and units assemble according to a plan or program. Generally, it is called as that an embedded system is a software system that has embedded into hardware that makes a system which is committed for an application or particular part of an application or part of a bigger system or product. It operates a fixed set of pre-programmed commands to control electromechanical apparatus that may be part of an even bigger system (not a computer with display, keyboard and many more).

A common definition of an embedded systems is that they are gadgets which are utilized to monitor, control or help the operation of machinery, plant or apparatus. An embedded considers the fact that they are an essential part of the system.

Characteristics of Embedded Systems

1). An embedded system is an application which is single and specifically functioned and that is popularly theoretical or the programs are performed repeatedly.

2). Efficiency is the main important for embedded systems, which are optimized for power, execution time, code size, cost, dimensions & weight.

3). Basically, Embedded systems are designed to connect real-time controls. A real-time system opposes to enhance from the managed object or operate within the time interval dominated by the environment.

4). The embedded systems frequently communicate (manipulate, communicate & sense) with the external world through actuators and sensors and consequently are typically reactive systems. And basically, a reactive system is a repeated interaction with the surroundings and performs at a pace which is resolute by that surroundings.

5). They basically have no user interface or minimal.

A computer chip which is used in an electronic system, but that is not a desktop, general-purpose workstation, or laptop computer. Some kind of systems uses microprocessors (MPUs) or microcontrollers (MCUs), or they may utilize custom-designed chips. It is established by the billions every year in unlimited applications and the embedded systems market basically utilizes the main share of electronic parts in the world.

All Kinds of Operating Systems

At present, there are established various embedded versions of Mac, Linux, and windows, as well as other important operating systems. Basically, embedded systems have limited storage and an embedded operating system is used as the designed to work in much less RAM than a desktop operating system. Generally, they also work in real time and small embedded systems may consist their own input or output routines and not need a particular operating system at all.

And an embedded systems also utilize a lot less energy than desktop systems which provides them a few more advantages in that they don’t need huge energy supplies and will also manufacture a lot of less heat, and in turn, removes the requirements for cooling. All embedded computing critical in a large number of applications and not only in the industry, but also in much of the technology we utilize every day, so remember that embedded solutions when you have a problem and you require solving, then it may just offer the answer that you are searching for.
