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.
