  MICROPROCESSOR • The microprocessoris a programmable integrated device that has computing and decision-making capability similar to that of the central processing unit(CPU) of the computer. • When microprocessor works as a CPU, then the system is called a microcomputer. A microcontroller is a small computer on the single integrated ckt. Containing a processor core, memory, and programmable input/output peripherals.

  µP Applications &Real-time Systems • Microprocessors are used to handle a set of tasks that control one or more external events or systems. • Microprocessors are typically used in either reactive or embedded systems. – Reactive systems are those that have an ongoing interaction with their environment - for example, a fire-control system that constantly reacts to buttons pressed by a pilot. – Embedded systems are those used to control specialized hardware in which the computer system is installed - for example, the microprocessor system used to control the fuel/air mixture in the carburetor of many automobiles. • In embedded systems the software system is completely encapsulated by the hardware that it controls.

  µP AS APROGRAMMABLE DEVICE • The fact that the µP is programmed means it can be instructed to perform given tasks within its capability. Similarly, today’s µP is designed to understand and execute the instructions. A programmer can select apt instructions and ask the µP to perform various tasks on a given set of data.
• 5.
  µP AS ACPU • A computer with a microprocessor as its CPU is known as a Microcomputer. The terms µP and µP unit(MPU) are often used synonymously. MPU implies a complete processing unit with the necessary control signals. But because of less pins, some of the signals need to be generated by using discrete devices to make the µP a complete functional unit or MPU.

  SOME EXCLUSIVE APPLICATIONS •The impact of microprocessor in different lures of fields is significant. The availability of low cost, low power and small weight , computing capability makes it useful in different applications. Now a days , a microprocessor based systems are used in instructions, automatic testing product, speed control of motors , traffic light control , light control of furnaces etc. Some of the important areas are mentioned below :
• 7.
  • Instrumentation: It isvery useful in the field of instrumentation. Frequency counters, function generators, frequency synthesizers, spectrum analyses and many other instruments are available , when microprocessors are used as controller. It is also used in medical instrumentation. • Control : Microprocessor based controllers are available in home appliances, such as microwave oven, washing machine etc., microprocessors are being used in controlling various parameters like speed, pressure, temperature etc. These are used with the help of suitable transduction.
• 8.
  • Communication : Microprocessorsare being used in a wide range of communication equipments. In telephone industry , these are used in digital telephone sets. Telephone exchanges and modem etc. The use of microprocessor in television, satellite communication have made teleconferencing possible. Railway reservation and air reservation system also uses this technology. LAN and WAN for communication of vertical information through computer network. • Office Automation and Publication : Microprocessor based micro computer with software packages has changed the office environment. Microprocessors based systems are being used for word processing, spread sheet operations, storage etc. The microprocessor has revolutionize the publication technology.
