Document Summary

An embedded system contains a computer embedded inside of it. The most common form of computer in use today is an embedded computer. An embedded system"s hardware and software are specifically designed and optimized to solve a single problem (or set of related problems) Embedded systems typically have a dynamic nature. They measure, control or interact with the outside world. Difference between a general purpose digital computer (gdpc) and an embedded. An embedded system"s hardware and software are optimized to solve a single problem. Many embedded systems do not have an operating system. Those that do, usually have a real-time operating system. The application program is contained in a non-volatile program memory. So, when the system is powered on, it immediately begins to execute its program. Variables and temporary data are contained in a volatile data memory. Addition of a computer/microcontroller mad reduce the purchase and operating cost of the system. Make it easier to add features to a system.
