Technology has advanced by leaps and bounds and today it serves mankind in every possible juncture. Embedded systems is one such outcome of technological advancement that is changing the life of common man in different fields. Basically, an embedded system is a device which performs a pre-defined function on a repetitive basis. They find usage in automobiles like cars where they are used for features like braking etc. Even cellular phones which are designed to perform certain complicated tasks contain these devices. Apart from them, other places where they find application are air-traffic control, MP3 players,digital watches, Mobiles, Planes, Trains and other alike wherein complexity of application of embedded system varies.
What is an Embedded System?
An embedded Electronic system is a system which dedicated to one or more functions to execute. It is a part of complete system which includes hardware, firmware, software and mechanical components. The embedded system is flexible to use with any other major systems to meet a wide range of specifications and end-user needs.
Different types of Embedded systems and its usage
The Embedded systems are typically pure hardware either Analog, Digital or with latest micro controllers or digital signal processors (DSP) etc. For example, Real Time System (RTS) which are using too many applications like Traction control (Railways for Electrical trains), Building Management Systems (BMS) implemented in M/s. CMC Limited building, Mumbai, first in India in 1992, Electrical Power Generation, control stations for regulating and controlling the power, air traffic control and communication systems etc.
As mentioned above, the embedded system is designed to execute one or two specific tasks. Since these systems are used for particular applications, the design engineer can reduce the size and cost by increasing the performance. The embedded systems has very wide applications, since they are portable in nature, example home security, Over head and under ground water tanks level controllers, domestic solar power systems, MP3 players, wide variety of electronic toys, mobile phones and Digital watches etc.
The embedded design can be done by ITI, Diploma and Engineering students or by any person who has interest in this field.
