  2. 2. Agenda   O Microprocessor O Microprocessor is important O Microprocessor Component O Application of Microprocessor O Types of Microprocessor O Can we use multi Microprocessor in PC? O Register types
  3. 3. WHAT IS MICROPOCESSOR?
  4. 4. O Microprocessors are integrated electrical circuits that are capable of carrying out the instructions of a computer software application or program. These electrical circuits receive instructions from the application or program, interpret these instructions and execute an action or set of actions, based upon what the instructions call for.
  5. 5. Why is a Microprocessor Important? O A device that uses a microprocessor is normally capable of many functions, such as word processing, calculation, and communication via Internet or telephone. However, for the device to work properly, the microprocessor itself has to communicate with other parts of the device. For example, a microprocessor would need to communicate with the video display to control the output data that a program may produce. Therefore, a microprocessor would act as device's "brain" in that it transmits, receives and interprets the data needed to operate a device.
  6. 6. Microprocessor O CPU etched on a chip O Chip size is ¼ x ¼ inch O Composed of silicon O Contains millions of transistors O Electronic switches that can allow current to pass through
  7. 7. Microprocessor Components O Bus interface unit] O Data & instruction cache memory O Instruction decoder O Arithmetic-Logic unit O Floating-point unit O Control unit
  8. 8. Microprocessor Data Cache Memory Bus RAM Bus Interface Unit I/O System Bus Control Unit Arithmetic & Logic Unit Instruction Decoder Registers Instruction Cache Floating Point Unit Registers
  9. 9. Applications of Microprocessor 1. General purpose application i) Single board micro computers ii) ii) Personal Computers iii) iii) Super Minis and CAD iv) 2. Special purpose application. v) i) Instrumentation vi) ii) Control vii) iii) Communication viii)iv) Office Automation and Publication
  10. 10. Types of Microprocessors Intel Intel-compatible O Pentium O Cyrix O Celeron O AMD O Xeon and Itanium
  11. 11. Types of Microprocessors O PowerPC O Cooperative efforts of Apple, IBM, and Motorola O Used in Apple Macintosh family of PCs O Found in servers and embedded systems O Alpha O Manufactured by Compaq O High-end servers and workstations
  12. 12. CAN WE USE MULTI MICROPROCESSOR IN PC? O PCs have dual-core central processors (CPU). That's one chip with two complete microprocessors on it, both sharing one path to memory and peripherals. O Does we can use many M P in computer O We can not use more than a microprocessor in the computer because everything that I said the number control units quality and speed of work
  13. 13. Registers Special-purpose High-speed Temporary storage Located inside CPU Instruction register Data register Holds instruction currently being executed Holds data waiting to be processed Holds results from processing
