Transcript

  • 1. • Processor
  • 2. Definition of Processor • Known as the Central Processing Unit (CPU) • A processor or ‘microprocessor’ is a microchip implanted in CPU’s hard drive that processes instruction sent to it by the computer and software
  • 3. Function • Interprets and carries out the basic instructions that operate the computer • Used to direct the operation of all other hardware devices and execute application instruction. Processors carry out these functions by processing digital information, receiving data and providing data
  • 4. Example of Processor
  • 5. CPU Components Control Unit (CU) Arithmetic Logic Unit (ALU)
  • 6. • A control unit is circuitry that directs operations within the computer's processor by directing the input and output of a computer system. The processor then controls how the rest of the computer operates (giving directions to the other parts and systems). • A control unit works by gathering input through a series of commands it receives from instructions in a running programs and then outputs those commands into control signals that the computer and other hardware attached to the computer carry out. . Control Unit
  • 7. Short for Arithmetic Logic Unit, ALU is one of the many components within a computer processor. The ALU performs mathematical, logical, and decision operations in a computer and is the final processing performed by the processor. After the information has been processed by the ALU, it is sent to the computer memory. Arithmetic Logic Unit (ALU)
  • 8. • Components of processor that direct and coordinates most of the operation in the computer • It interprets issued by program and the initiate the appropriate action to carry out the instruction. Computer Unit Arithmetic Logic Unit • Performs arithmetic, comparisons, and logical operations. • Arithmetic operations include additions, subtractions, multiplication, and division. • Logic operation involve comparing data either more than, less than or equal.
  • 9. Machine Cycle Fetching Process of obtaining program instruction or data item from memory Decoding Process of translating the instructions into the signals the computer can execute. Executing Process of carrying out of commands. Performs the request instruction such as adding two number or deciding which one of the is larger Storing Store the result to an internal register ( a temporary storage location or to memory) Third Step Second Step First Step Fourth Step
