What is an embedded system? Can Mobile be considered as an embedded product?

Question

What is mean by embedded system?

If a system/machine or product which we are making is for multiple purposes, then can we consider it as an embedded system? Or is it tha

Answer 1

Generally an embedded system is one placed into operation for a specific, narrow purpose, and lacking the kind of general purpose user interfaces you would find on an ordinary desktop/laptop.

That is not to say though that an embedded system cannot have these - I've seen test equipment such as network analyzers running desktop operating systems, with mouse/keyboard ports. One could probably hack one of those to use it for general purpose computing, but it would not be cost effective.

Going the other way, you can take a general purpose computer and shove it into an embedded application. However, systems optimized for embedded use may be more robust, support better real-world I/O (often retaining legacy ports), and use parts expected to be available over longer lifetimes than used in commodity PCs (if one fails, you want to be able to replace it with the exact same thing).

Often embedded systems are smaller - 8 bit processors (even 4-bit or serial-core historically) with limited memory; though 32 bit cores such as the arm family are now inexpensive and commonplace. Nor are tens to hundreds of megabytes of memory unknown.

Older cellphones would have a lot in common with embedded systems, but rather obviously contemporary smartphones are catching up in power and versatility, though still often constrained by user interface. Software wise some "think small" habits endure - for example, Android's compact bionic C library and toolbox shell have similar design goals to embedded C libraries and busybox. In other ways though, expansive resource-gobbling user experiences are now the norm on phones. Toss tablets based on the same processors and accessorized with keyboard into the mix, run a kernel designed originally for desktop computers on them, and the real difference is between UI software stacks designed to run segregated "apps" on a touch interface, vs one designed to run more traditional programs.

Answer 2

A definition that may help to get the difference. An embedded system can be considered as a system with which another embedded system cannot be developed. So presently, using a mobile phone, one cannot develop an 'embedded system'. If it is possible by the mobile device, then it should be considered as a general purpose system.

Answer 3

An embedded system is any electronic system that uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. An embedded system is a special-purpose computer system designed to perform a dedicated function. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few pre-defined tasks, usually with very specific requirements, and often includes task-specific hardware and mechanical parts not usually found in a general-purpose computer.

Answer 4

The embedded system is a microprocessed system in which a computer is attached to the system it controls. An embedded system can perform a set of tasks that have been predefined. The system is used for specific tasks, and thus, through engineering it is possible to optimize a given product and decrease the size, as well as the computational resources and its final value.
Embedded systems are all around us, and for that reason, we are not aware of their computational capacity, since we are so involved with such mechanisms. Embedded systems operate on machines that can work for several years without stopping, and which still, in some cases, have the ability to self-correct.

An excellent example of items that use embedded systems are the famous smartphones, which perform specific functions, and which have more limited mechanisms than computers.

Check below a list with some examples that receive the application of embedded systems:

1. Electronic ballot box
2. Video games
3. Calculators
4. Printers
5. Hospital equipment
6. In vehicles
7. Some home appliances
8. Cellular apparatus
9. Routers

Answer 5

An example of an "embedded system" is a chip that is inserted underneath a dog's skin for identification purposes. Words like "embedded system" have specific meanings that only specialists understand. Such ambiguities make understanding technical language difficult for ordinary people.

embedded (ɪmˈbɛdɪd) adj

1. fixed firmly and deeply in a surrounding solid mass
2. constituting a permanent and noticeable feature of something
3. (Journalism & Publishing) journalism assigned to accompany an active military unit
4. (Grammar) grammar inserted into a sentence
5. (Computer Science) computing (of a piece of software) made an integral part of other software

Answer 6

Embedded system are devices that do some specific job not like our laptops which can play music, click pictures and format documents. They are devices like water filter , washing machines, vending machine etc. They are programmed for some specific work and they do that work in a super loop depending on the user input.Like the vending machine always perform same thing when you opt for coffee in it with the help of button provided in it.

So in that way mobile phone is not an embedded system because it has no super loop and it can do various general purpose things just like a computer.

An embedded system has memory constrain, timing constrain and they do things in limited space.
