In simple terms, embedded systems are computer systems ’embedded’, planted or enclosed within a larger system for the purpose of carrying out some specific functions. Embedded systems control many devices commonly used today.

Key Features of Embedded Systems

1. Embedded systems are designed to accomplish a specific task.

2. They are characterized by small size, low cost, low power consumption, impressive operating ranges etc.

3. On the negative side, embedded systems are more difficult to program and interact with.

4. The main components of embedded systems are microcontrollers and microprocessors. Microcontrollers are processing units with integrated memory while microprocessors are processing units with external memory. Microcontrollers are used in applications where a general computer would be too costly.

5. Embedded systems could be simple, e.g. a single microcontroller chip, or complex, e.g. an enclosure of multiple units, peripherals and network mounted inside a large vessel.

6. Embedded systems are not standalone devices. For the most part, they consist of small units within a larger device serving a more general purpose.

Uses of Embedded Systems

1. The existence of embedded systems within a product helps to reduce the size and cost of the product. It also increases its reliability and performance. 2. Embedded systems provide products with flexibility, distinct features and flexibility.

3. They are typically designed to meet the requirements for real time systems. A real time system is a system which is dictated by the environment.

4. Embedded systems can be found in almost all sectors of the economy; residential, industrial, telecommunications, transportation, medical sectors etc.

Applications of Embedded Systems

Consumer and Household Applications
Mobile phones, audio players, video game pads or consoles, digital cameras, DVD players, washing machines, microwave ovens and dishwashers employ embedded systems. Home automation systems use embedded devices for sensing and controlling.

Industrial Applications

Several electric motors used in industries use electronic motor controllers, e.g. brushless DC motors and induction motors.

Telecommunications Applications

Switches, routers and bridges used in telecommunications stations are made up of numerous embedded systems.

Transportation Applications

Transportation systems, e.g. automobiles and airplanes, electric and hybrid vehicles use embedded systems to reduce pollution and maximize efficiency. Check this used car dealerships surrey.

Medical Applications

Embedded systems within medical equipment such as the electronic stethoscope are used for amplifying sounds, monitoring vital signs, and imaging or scans for internal inspection.

The term ’embedded’ rightly reflects the fact that these systems are an integral part of the general system in which they are found. It is obvious from the applications that embedded systems are almost everywhere. Gradually, they have seeped into every area of human life, from the watches we wear on our wrists every day, the printers used in our homes and offices, to the GPS devices in our cars and mobile phones. The embedded systems have taken over the world. But they are welcome to do so, and even more. Imagine life without these integral systems: Dreary, frightfully dull, uncomfortable and basically, uninhabitable.

Embedded systems provide us with the ability to communicate with one another, travel anywhere we want, and beat our friends in video games after a hard day at work. So, yes, embedded systems have taken over the word, but we are all the more grateful for it.
