1.1 INTRODUTION TO EMBEDDED SYSTEM
1.1.1 DEFINITION
Combination of Software and hardware, designed to perform a particular task .Eg: Printer, Timers, Remote controls, Digital locks, Lighting control, Keyboard. An embedded controller is a controller (or computer) that is embedded into some device for some purpose other than to provide general purpose computing. Perform a single set of functions. Works in a time constrained environment. Provides high-performance and reliability Mostly Embedded systems have low cost because they are mass produced in millions. Some Embedded systems have mechanical moving parts like disk drives as they are less reliable as compared to solid state parts such as Flash memory.
1.1.2 WHAT IS EMBEDDED TECHNOLOGY
July 12, 2001 Simply,embedded technology is software or hardware that is hidden embedded in a large device or system. It typically refers to a fixed function device, as compared with a PC, which runs general-purpose applications. Embedded technology is nothing new. It's all around us and has been for years. An early example of embedded technology is the engine control unit in a car, which measures what settings to give the engine. Your coffeemaker has embedded technology in the form of a microcontroller, which is what tells it to make the coffee at 6 a.m. The vending machine has it too. Overall, billions of devices woven into everyday life use embedded technology.
