the cpu and fetch exucute cycle

1. fetch

1.1. data and instructons are transferred from RAM

2. decode

2.1. the control unit interpretes the intrusction

3. exucute

3.1. the control unit then carries out the instruction

4. clock

4.1. coordiates all of its components by sending out an electrical pulse

5. controll unit

5.1. controlls the flow of data in the system

6. the imediate accessstore

6.1. where all the spus data and programs are held

7. ALU(arithmetic logic unit)

7.1. does all the calculations and logic for the cpu and solves them

8. registers

8.1. registers are small amounts of high speed memory within the cpu

8.2. MAR,MDR,

8.2.1. MDR hols the actal data

8.3. the MAR holds the address that the data is going to be sent

9. cache

9.1. cache is high speed memory it can only temporarily hold data quicker than RAM

10. buses

10.1. they are used to send controll signals around at a high speed connection
