Microprocessors and Applications
When discrete components and integrated circuits played a vital role in technology development, the advent of microprocessor has changed completely the system design for various real time applications.
A microprocessor is a programmable electronics chip that has computing and decision making capabilities similar to central processing unit of a computer. Any microprocessor based systems having limited number of resources are called microcomputers. Nowadays, microprocessor can be seen in almost all types of electronics devices like mobile phones, printers, automotive electronics, home appliances, electronic toys, and a variety of industrial applications.
