What Is an Embedded System
Embedded systems are those systems which are designed to do a specific task depending upon their need like cellphone.
In Embedded Systems there are various units which are assembled to work together.
An Embedded System is made up of hardware and a software which is burned to hardware. The software programmed on Personal Computer (generally language used behind the software is embedded C in which code is written and run on IDE or IDP to generate HEX file to design all embedded system) and then it is burned to that embedded system's hardware to perform a task.
Designing Of Embedded System
An Embedded System is a smart and a small computer(always fit in your pocket) which have capabilities to do some specific task, it consumes low power and moreover it is cost friendly. So it becomes very important to get a perfect design and a compatible design.
As embedded systems comprises of three units Input unit,Processing Unit,Output Unit.
Input unit consists of transducers or sensors which are used to input signals (those signal are in millivolts) to the embedded system.
If the embedded system is automatic the sensors such as IR sensor, proximity sensor, Temperature, ultra sonic sensor, UV sensor, touch sensor etc or transducers will be used to initiate the input.
And in case of manual system there will always be some mechanism such as a button in the input.And in case of manual system there will always be some mechanism such as a button in the input.
To make a system intelligent there is a processing unit which gets the input signals and provide desired output signals.But this is not done by itself. There is an important part which is called micro controller and is the brain of an embedded system. This is the component which is programmed with the help of a computer to perform the desired operation. It receives all the input and and reacts according to the program to provide output signals.
The output unit is responsible to provide all the output which are desired by the embedded system. The output unit get it's output signal from the micro controller and then act according to it. There may be a motor, an LCD,led or a buzzer connected to the output to generate human recognizable output.
Other units such as power supply is also installed generally operate on 5-12 Volts with an embedded system. The above units may varies according to their need. There will be a micro controller which will always used in processing unit which requires a 5 Volt supply. To make these units fit together in a small pack proper designing is required and the system must be compatible and cost friendly.
Now you are familiar with basic things about an embedded system. Now you must know about those embedded systems by whom we are surrounded. The best example is our Cellphone.
Other examples are home security systems such as burglar alarm, mp3 player, TV remote, digital camera, a scientific calculator, digital watch, video game console and many more.
So in our modern world we cannot imagine things without embedded systems. It is easy to create your own embedded system. With us you all will know and learn all about an embedded system. So remain connected with us and tell us your thoughts about this post in comments.
