An embedded system usually does not look like a computer, often there is no keyboard or monitor or mouse. But like any computer, it has a processor and software, input and output. The word embedded means it is built into the system. It is a permanent part of a bigger system. Rajkamal clearly explained about this book in a manner and we can understand definitely without any problem.

For example, a controller is embedded in an elevator and tells the motor to move the elevator to different floors based on buttons that are pushed. A decoder is embedded in a satellite television set-top box to read a signal from the dish and send something that a TV understands. Often this type of system must do its work in a specific amount of time. This is called real-time computing. If a set-top box got interrupted to do another task, you would see a bad picture on the TV, for example. A general purpose computer will often have short pauses while it does something else, it is not real-time. Embedded Systems textbook by Rajkamal Free download pdf.

Embedded systems control many of the common devices in use today, from card readers in hotel door locks to many controls in a car. They can be small like an MP3 player or a digital camera, to large systems like traffic lights, airplane controls, or assembly line controllers in a factory.

Common features of Embedded Systems textbook by raj kamal

• Embedded systems are designed to do a specific task, unlike general-purpose computers.
• It does not look like a computer – there may not be a full monitor or a keyboard.
• Many embedded systems must be able to do things in real-time – in a short amount of time (almost instantly from a human view).
• Many embedded systems must be very safe and reliable, especially for medical devices or avionics controlling airplanes.
• Starts very quickly. People don’t want to wait a minute or two for their car to start or emergency equipment to start.
• It uses a special operating system (or sometimes a very small home-made OS) that helps meet these requirements called a real-time operating system, or RTOS.
• The program instructions written for embedded systems are referred to as firmware and are stored in read-only memory or flash memory chips. They run with limited computer hardware resources: little memory, small or non-existent keyboard and/or screen.
