Central Processing Unit
CPU
John Von Neumann architechure used the idea of holding programs in memory and data would then move between the memory unit and the processor.
Von Neuman architecture
Control Unit retrieves data and instruction in the same manner from one memory. Design and development of the Control Unit is simplified, cheaper and faster.
Effect of Von Neumann architecture
The processor responds to and processes the instructions that drive the computer.
Definition processor
Control Unit (CU), the Arithmetric Logic Unit (ALU) and registers.
Components of the processor
The program instructions and data move between teh main memory and the processor using internal connections called buses.
Buses
Address bus
Data bus
Control bus
Three types of buses:
Carries addresses from the processor to memory and input/output devices
Address bus
Send data between the processor, memory and input/output devices
Data bus
Carries signals to coordinate all the computer activites
Control bus
