Embedded system Simple English Wikipedia, the free encyclopedia. An embedded system is a computer that has been built to solve only a few very specific problems and is not easily changed. In contrast, a general purpose computer can do many different jobs, and can be changed at any time with new programs for new jobs. An embedded system usually does not look like a computer, often there is no keyboard or monitor or mouse. But like any computer it has a processor and software, input and output. The word embedded means it is built into the system. It is a permanent part in a bigger system. SamLogic is a company that develops software for Windows. E. g. CD DVD USB autorun menu tool CDMenu Creator, installation setup tool Visual Installer and email.

For example, the controller embedded in an elevator tells the motor to move the elevator to different floors, based on buttons that are pushed. A decoder is embedded in a satellite television set top box to read a signal from the dish and send something that a TV understands. Often this type of system must do its work in a specific amount of time. This is called real time computing. If a set top box got interrupted to do another task, you would see a bad picture on the TV, for example. This is a comprehensive list of neardeath experiences related television programs and shows about the afterlife and the paranormal.

A general purpose computer will often have short pauses while it does something else, it is not real time. Embedded systems control many of the common devices in use today, from card readers in hotel door locks to many controls in a car. They can be small like an MP3 player or a digital camera, to large systems like traffic lights, airplane controls, or assembly line controllers in a factory. Embedded systems are used in many kinds of electrical devices, including Telecommunications systems uses them for telephones, cell phone network, and wi fi routers.

Consumer electronics include broadcast receivers, MP3 players, mobile phones, video game consoles, digital cameras, DVD players, GPS receivers, home security systems, and printers. Household appliances, like microwave ovens, washing machines, burglar alarm systems and dishwashers have embedded systems. Transportation uses embedded systems for everything from locomotives for trains, airplanes and automobiles. Industry uses electric motors with electronic controllers, card readers and CNC machines which automatically make metal parts. Medical devices like defibrillators, automated blood pressure readers, and automated insulin pumps. Military devices, like walkie talkies, satellites and the guiding systems for missiles. Embedded systems are designed to do a specific task, unlike general purpose computers. It does not look like a computer there may not be a full monitor or a keyboard. Many embedded systems must be able to do things in real time in a short amount of time almost instantly from a human view. Many embedded systems must be very safe and reliable, especially for medical devices or avionics controlling airplanes. Starts very quickly. People dont want to wait a minute or two for their car to start or emergency equipment to start. It may use a special operating system or sometimes a very small home made OS that helps meet these requirements called a real time operating system, or RTOS. The program instructions written for embedded systems are referred to as firmware, and are stored in read only memory or flash memory chips. They run with limited computer hardware resources little memory, small or non existent keyboard andor screen. Embedded systems are not always standalone devices. Sometimes they are built as a set, like the various parts of a car the radio, the throttle control, the pollution control, etc. Sometimes they can communicate to the internet or a cell phone network and they may have a USB reader or other connections. An example of a user interface with buttons and a simple LCD display. Embedded systems range from no user interface at all only sending and receiving electric signals to a full graphical user interface like on a modern computer. Quite often they will have a few push buttons and a small display and some LEDs. A more complex system may have a touch screen, allowing the meaning of the buttons to change with each screen as in smart phones. Hardware includes the chips, wires, circuit boards, buttons and displays. The most important chip is the central processing unit or CPU. This runs the software instructions. It can be a standard microprocessor or a microcontroller. Microcontrollers include the microprocessor as well as simple peripheral equipment so the system can be smaller and cheaper. They have less flexibility because those parts cannot be changed. Usually these parts include Flash memory and support for serial ports, USB, etc. Unlike a microprocessor for a general purpose computer, bigger and faster is not always better. Many embedded processors are very small. Sometimes this is to use less space or less power, sometimes it is to be cheaper. General purpose computers will use microprocessors that read 3. GHz, but embedded processors are usually 4 to 3. MHz a hundred times slower. But the programs are also smaller and do not check for things that are not used. Soekris net. 48. 01, an embedded system targeted at network applications. There are ready made computer boards that can be used in some embedded systems. These often use Windows CE, Linux, Net. BSD, or an embedded real time operating system. Sometimes it may be easier to use a circuit board that is already made. These usually share many components with general purpose computers, but are smaller than one in a general purpose computer. Boards such as the VIA EPIA can run Microsoft Windows. The advantage is that it saves some electrical engineering time and can use the same software development tools used for PC type software development. Examples of such embedded devices are the ATMs or displays in casinos. This works well if the real time requirements are not real strict it doesnt matter much if a job takes eight seconds instead of five, for example. If the device needs to be very small or will be sold in very big numbers high volume, it makes sense to make a custom or specialized chip that does exactly what is needed. This is a system on a chip So. C which holds a complete system processor, floating point unit, memory cache and interfaces on a single integrated circuit. So. Cs can be made as a special order application specific integrated circuit ASIC or by using a field programmable gate array FPGA which is programmed by the people building the embedded system. Embedded systems talk with the outside world or other components using peripherals such as Serial Ports RS 2. RS 4. 22, RS 4. This used to be quite common, with the 9 pin or larger connectors.

Embedded systems often do not need a full operating system. Some use specially built small and simple operating systems that start very quickly, others do not need one at all. Embedded systems are not adapted as easily, but they are built to perform their tasks much more reliably. Software Wikipedia. Photoshop Cs6 3D Text Plugin Free Download. Computer software, or simply software, is a part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built. In computer science and software engineering, computer software is all information processed by computer systems, programs and data. Computer software includes computer programs, libraries and related non executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own. At the lowest level, executable code consists of machine language instructions specific to an individual processortypically a central processing unit CPU. A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computeran effect that is not directly observable to the user. An instruction may also indirectly cause something to appear on a display of the computer systema state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to jump to a different instruction, or is interrupted by now multi core processors are dominant, where each core can run instructions in order then, however, each application software runs only on one core by default, but some software has been made to run on many. The majority of software is written in high level programming languages that are easier and more efficient for programmers to use because they are closer than machine languages to natural languages. High level languages are translated into machine language using a compiler or an interpreter or a combination of the two. Software may also be written in a low level assembly language, which has strong correspondence to the computers machine language instructions and is translated into machine language using an assembler. History. An outline algorithm for what would have been the first piece of software was written by Ada Lovelace in the 1. Analytical Engine. However, neither the Analytical Engine nor any software for it were ever created. Equalizer Software Windows Media Player. The first theory about softwareprior to creation of computers as we know them todaywas proposed by Alan Turing in his 1. Computable numbers with an application to the Entscheidungsproblem decision problem. This eventually led to the creation of the twin academic fields of computer science and software engineering, which both study software and its creation. Computer science is more theoretical Turings essay is an example of computer science, where as software engineering focuses on more practical concerns. However, prior to 1. The first electronic computing devices were instead rewired in order to reprogram them. Types. On virtually all computer platforms, software can be grouped into a few broad categories. Purpose, or domain of use. Based on the goal, computer software can be divided into Application softwarewhich is software that uses the computer system to perform special functions or provide entertainment functions beyond the basic operation of the computer itself. There are many different types of application software, because the range of tasks that can be performed with a modern computer is so largesee list of software. System softwarewhich is software that directly operates the computer hardware, to provide basic functionality needed by users and other software, and to provide a platform for running application software. System software includes. Operating systemswhich are essential collections of software that manage resources and provides common services for other software that runs on top of them. Supervisory programs, boot loaders, shells and window systems are core parts of operating systems. In practice, an operating system comes bundled with additional software including application software so that a user can potentially do some work with a computer that only has one operating system. Device driverswhich operate or control a particular type of device that is attached to a computer. Each device needs at least one corresponding device driver because a computer typically has at minimum at least one input device and at least one output device, a computer typically needs more than one device driver. Utilitieswhich are computer programs designed to assist users in the maintenance and care of their computers. Malicious software or malwarewhich is software that is developed to harm and disrupt computers. As such, malware is undesirable. Malware is closely associated with computer related crimes, though some malicious programs may have been designed as practical jokes. Nature or domain of execution. Keygen 3Ds Max 8. Desktop applications such as web browsers and Microsoft Office, as well as smartphone and tablet applications called apps. There is a push in some parts of the software industry to merge desktop applications with mobile apps, to some extent. Windows 8, and later Ubuntu Touch, tried to allow the same style of application user interface to be used on desktops, laptops and mobiles. Java. Script scripts are pieces of software traditionally embedded in web pages that are run directly inside the web browser when a web page is loaded without the need for a web browser plugin. Software written in other programming languages can also be run within the web browser if the software is either translated into Java. Script, or if a web browser plugin that supports that language is installed the most common example of the latter is Action. Script scripts, which are supported by the Adobe Flash plugin. Server software, including. Plugins and extensions are software that extends or modifies the functionality of another piece of software, and require that software be used in order to function Embedded software resides as firmware within embedded systems, devices dedicated to a single use or a few uses such as cars and televisions although some embedded devices such as wireless chipsets can themselves be part of an ordinary, non embedded computer system such as a PC or smartphone. In the embedded system context there is sometimes no clear distinction between the system software and the application software. However, some embedded systems run embedded operating systems, and these systems do retain the distinction between system software and application software although typically there will only be one, fixed, application which is always run. Microcode is a special, relatively obscure type of embedded software which tells the processor itself how to execute machine code, so it is actually a lower level than machine code. It is typically proprietary to the processor manufacturer, and any necessary correctional microcode software updates are supplied by them to users which is much cheaper than shipping replacement processor hardware. Thus an ordinary programmer would not expect to ever have to deal with it. Programming tools. Programming tools are also software in the form of programs or applications that software developers also known as programmers, coders, hackers or software engineers use to create, debug, maintain i.
