2013-09-14 10:21:05 - Today is the time of computers and machines. The life of every individual is dependent upon it, virtually, for one or the other reason. It is unimaginable to perform any task without getting an access to the virtual world. Embedded systems are another contrivance that has become quite popular and hot favorite in the electronics sessions nowadays. If one begins to describe the utility and names of the products and items where embedded systems play crucial role, one would actually run out of space and breathe too. The list is exhaustive and never ending as microprocessor and microcontrollers are an essential and intrinsic part of any work.
Microcontroller can be defined as one-of-its-kind of microprocessor, which once integrated into a single chip, can help build integrated circuits as it has the core processor, input-output peripheral. Thus, the microcontrollers come in use to accumulate the data from the input. Microprocessors and microcontrollers are invariably the same only, as they work upon the operation of inputs and output of any product. This however is the very basic or fundamental function of microcontroller. Measurements, communication access and access to various kinds of information switching are few of the other facilities which microcontroller makes possible. The knowledge for the programming of microprocessor and microcontroller helps the person stand out in any crowd. Therefore, there are millions of people who have been
taking programming tutorials and trainings for microcontroller 8051 specifically.
In today times, appliances which are used increasingly by making use of microcontroller are listed below:
• office machines
• washing machines
• remote controls
• power tools
• automobile control systems
• medical devices
Initially the language used for programming microcontroller was assembly language but with its rising popularity, the level of programming languages has also become high-level. There are many features which a microcontroller possesses:
• ROM, CPU, RAM, timers
• It is an independent, self contained unit
• User specific designed for controlling a particular system
• Mainly CMOS used for its designing
Apart from the above mentioned features, microprocessor and microcontrollers are used for many other applications. Few of these include:
• Automotive systems
• Communication system devices such as cell phones, FAX machines or cable TV
• Computer devices such as DRAM, LAN and laser printer controller
• ECG display cum recorder, blood cell analyzer and patient monitoring system
• CRT display controller
The kind of popularity and growth embedded systems have marked in the span of last few years is worth noticing and applauding. With the advent of robotics in every individual life, day to day activities have smoothened, fastened and become easier, which gives them the time to perform other essential tasks as well.
