Architecture - Von Neumann

About

The Von Neumann organization is the most and well known organization (a sort of reference).

It implements a instruction cycle (fetch, decode, execute, store) with the following components:

• the CPU to fetch instructions from main memory and execute
• the memory to store program code and data
• One or more bus. Today, a computer has several buses, each specialized in a type of traffic:
  • the data bus to transfer data,
  • the address bus to transmit the location information,
  • the control bus to provide information as to how data is being sent
• I/O Devices:
  • input device to give input to the computer: keyboard, mouse, sensor, etc
  • output device to take information from the CPU: monitor, LED , …

The data does not move. Only the instruction pointers
