Central Processing Unit

My presentation about the history parts and functions of the CPU on the computer system. ENJOY~

1. CPU (Central Processing Unit)

2. Table of Contents : Objective What is CPU? History of Central Processing Unit. Components of CPU. Function of the CPU. Assessment on your understanding.

3. Objective: To understand more and gives an idea on how the brain of computer works, by interpreting it’s history , component and functions. Back

4. What is CPU? The Central Processing Unit (CPU) is simply the central processor or the processor where most calculation takes places. The Brain of the Computer. The "fixed-program computers. Back

5. History of Central Processing Unit Back

6. CPU started: In the '40s, mathematicians  John Von Neumann, J. Presper Eckert and John Mauchly came up with the concept of the stored instruction digital computer. On 1970’s a component of mainframe computer known as CPU is a steel cabinet bigger than a refrigerator full of circuit boards crowded with transistors.

7. In 1971 the first microprocessor invented. The 4004 microprocessor . In 1972 The 8008 was the first of many 8- bit microprocessors to fuel the home computer revolution. In 1979, Intel delivered the 8088 and IBM engineers used it for the first PC . From 8086 .

8. Cache RAM invented by the microprocessor engineers . Cache Grows Up Cache Splits Up CPU made smaller and faster.

9. Components of CPU Back

10. Component Control Unit Arithmetic Logic Unit Memory Unit/Register

11. Description ALU(Arithmetic Logic Unit)- performs simple arithmetic and logical operations . CU(Control Unit)-It reads and interprets instructions from memory and transforms them into a series of signals to activate other parts of the computer. MU/Register(Memory Unit)- is the part of the computer that holds data and instructions for processing.

12. Function of the CPU Back

13. Fetch - taking the instruction from the memory. Decode- translating and decoding Assembly code binary instructions which are understandable to your CPU. Execute- execute calculation, move data and jump to different address. Store- CPU dive some data after executing the instruction and store data being instructed.
