CPU Components

• The Control Unit (CU) sends control signals to direct the operation of the CPU.
• Control signals and timing signals are sent to the ALU and other components such as RAM.
• A register is a temporary storage space for one instruction or address.
• ALU stands for Arithmetic Logic Unit and it performs simple calculations and logical operations.
• Cache memory is used to temporarily store data that is frequently accessed.
• Cache memory is split into different levels.
• Cache is slower to access than the registers but much faster than RAM.
