Cpu.9

  1. 1. ObjectiveOn completion of this period, you would be able to learn: Functional Blocks of CPU. http://improvec.blogspot.in/ 1
  2. 2. Recap What is a computer? It is an electronic device which processes the computer’s data. Functional units of computer. Input unit, memory unit, CPU, output unit. http://improvec.blogspot.in/ 2
  3. 3. Prerequisites What are parts of the computer? Input unit ,memory unit, CPU, output unit. What is CPU? Central Processing Unit. http://improvec.blogspot.in/ 3
  4. 4. CPU(Central processing unit) http://improvec.blogspot.in/ 4
  5. 5. CPU CPU is the heart and brain of the computer. It receives data as input. It processes the data according to the instructions. And gives results as output. http://improvec.blogspot.in/ 5
  6. 6. CPU (contd) Its primary function is to execute programs. Beside executing programs, the CPU also controls the operation of all other components such as memory, input and output devices. http://improvec.blogspot.in/ 6
  7. 7. CPU (contd) Under its control , programs and data are stored in the memory And it displays the data on the CRT screen or prints on the printer. The CPU of a small computer is called microprocessor. http://improvec.blogspot.in/ 7
  8. 8. CPU (contd...) The CPU of a large computer contains a number of microprocessors and other ICs on one or more circuit boards. http://improvec.blogspot.in/ 8
  9. 9. Functional Block of CPU ALU (Arithmetic & Logical Unit) Timing & Control unit Registers http://improvec.blogspot.in/ 9
  10. 10. Blocks of CPU:Fig 1 http://improvec.blogspot.in/ 10
  11. 11. CPU (Central processing unit) :ALU (Arithmetic Logic Unit) :  It performs two types of operations 1. Arithmetic Operations 2. Logical operations. http://improvec.blogspot.in/ 11
  12. 12. Arithmetic operations 1. Addition(+) 2. Subtraction(-) 3. Multiplication(*) 4. Division(/)Logical operations: AND OR NOT EXCLUSIVE OR http://improvec.blogspot.in/ 12
  13. 13. Timing & Control unitActs as the brain of a computerIt controls the operations of a CPUSynchronizes the operations of variousdevicesGenerates timing signals such thatcoordination among devices take place http://improvec.blogspot.in/ 13
