EMBEDDED SYSTEMS:

              Embedded Systems are a combination of hardware and software integration, accomplished for a specific function. Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some also have real-time performance constraints that must be met, for reasons such as safety and usability.

           Embedded systems are not always standalone devices. Many embedded systems consist of small, computerized parts within a larger device that serves a more general purpose.

            Embedded systems span all aspects of modern life and applicable in different areas like manufacturing industries, auto mobile industries, communication systems, Medical electronics technology, telecommunication systems, real time applications, non real time applications and defense, aero space areas, etc.

  

DIGITAL IMAGE PROCESSING is the use of computer algorithms to perform image processing on digital images. As a subfield of digital signal processing, digital image processing has many advantages over analog image processing; it allows a much wider range of algorithms to be applied to the input data, and can avoid problems such as the build-up of noise and signal distortion during processing.

 

DIGITAL SIGNAL PROCESSING is the technique used to analyze various digital signals and obtain information from the same. DSP is concerned with the representation of signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing.  DSP is one of the most powerful technologies that will shape science and engineering in the twenty-first century.

VLSI

Very large-scale Integration is a process of creating integrated circuits by combining thousands of transistors and resistors into a single chip. This is the field which involves packing more and more logic devices into smaller and smaller areas. VLSI, circuits that would have taken boardfuls of space can now be put into a small space few millimetres across!

                 This has opened up a big opportunity to do things that were not possible before. VLSI circuits are everywhere ...in computers, car, brand new state-of-the-art digital camera, the cell-phones VLSI began in the 1970s when complex semiconductors and communication technologies were being developed. The microprocessor is a VLSI device. The term is no longer as common as it once was, as chips have increased in complexity into billions of transistors.
EEE:Matlab is an interactive system for doing numerical computations. A numerical analyst called Cleve Moler wrote the first version of Matlab in the 1970s. It has since evolved into a successful commercial software package. Matlab relieves you of a lot of the mundane tasks associated with solving problems numerically. This allows you to spend more time thinking, and encourages you to experiment. Matlab makes use of highly respected algorithms and hence you can be confident about your results. Powerful operations can be performed using just one or two commands. You can build up your own set of functions for a particular application. Excellent graphics facilities are available, and the pictures can be inserted into LATEX and Word documents.
