Extra activity I- Central Processing Unit( CPU) Overview
Description
This activity is designed to give a basic understanding of the workings of a computer.
For this activity we define a computer as being comprised of three components: CPU- Control Unit & Arithmetic Logical Unit Memory
Display( acting as the output) You are given a simple computer program to run( Program1, Program2), this is the input to the system. The“ CPU” needs to fetch instructions and data from memory and execute the instructions( CU). It also needs to perform mathematical and logical functions( ALU) and tell the“ Display” what to do. The“ Display” need to hide what they are drawing, only once the program is completed, can the result be shown.
Setup
Assign your role.
CPU( working with the program counter sheet) will request instructions and data from memory, as required. These parts will also process any necessary calculations, writing results back to memory and instructing the display how to plot the data.
