    Study Notes

    CPU Components and Functions

    • The Arithmetic Logic Unit (ALU) performs arithmetic involving integers and logical operations.

    Control Unit

    • The main function of the Control Unit is to retrieve and decode instructions and manage the flow of data between different parts of the CPU.

    Memory Hierarchy

    • The Cache Memory stores data and instructions needed by the CPU.

    Instruction Fetch

    • The Prefetch Unit retrieves instructions from memory and holds them until they are required by the CPU.

    Instruction Decoding

    • The Decoder translates instructions from the prefetch unit so they are understood by other CPU components.
