Lesson Intent

Learning Objectives:
  1. Know the common CPU components and their function: ALU (Arithmetic Logic Unit), CU (Control Unit), Cache, Registers
  2. Understand Von Neumann architecture:
    MAR (Memory Address Register), MDR (Memory Data Register), Program Counter,
    Accumulator
  • Explain each of the parts of the CPU and their function.
  • Know the main registers in the CPU, define them and explain their purpose.

Implementation

Resources
Starter:
Complete the review questions from last lesson about the purpose of the CPU and the Fetch Decode and Execute cycle.

Main:
Introduction to the main parts of the CPU and their function.  Also the four main registers inside the Von Neumann CPU, record the notes in exercise books.  Use the 'cut out' diagram worksheet to create your own paper CPU.
