Q. Working of Microprocessor Control?

The microprocessor, which has rapidly become a key component in digital control systems, and its associated circuits function as the digital processor. It is often used as a dedicated computer in which the chip itself is programmed to perform specific functions. Digital watches and auto fuel-injection systems are examples. With microprocessor control, not only the same hardware can be used to perform a variety of tasks by reprogramming, but also distributed computation (which results in less expensive and more reliable operation than centralized control) is possible with interconnection and intercommunication of several microprocessors.
