Central Processing Unit (CPU)

• The CPU is the central processing unit of a computer.
• Its major components include:
  • Arithmetic/Logic Unit (ALU): Temporarily holds data for calculations
  • Control Unit (CU): Manages and interprets instructions for execution
  • Input/Output (I/O) Interface Units: Moves instructions and data between the CPU and other hardware components.
  • Memory: Repository for processes and data

Memory Unit

• Memory Management Unit: Supervises fetching instructions and data from memory; I/O interface is part of the control unit; Bus interface combines input and output
• Memory Address Register (MAR): Holds the address of a memory location
• Memory Data Register (MDR): Holds data values being stored in or retrieved from memory. MDR also known as memory buffer register

Registers

• A single, permanent storage location within the CPU used for a particular purpose
• Used to hold binary values temporarily for: storage, manipulation, and simple calculations
• Each register is wired within the CPU for specific roles
• Usual size ranges from 1 to 128 bits
• Kinds of registers: Accumulator, General-purpose registers, User-visible/program-visible, Program Counter Register, Instruction Registers, Status Registers, I/O Registers, Memory Address Registers, Memory Data Registers.

Register Operations

• Loading: Transferring values from other registers or memory locations into a register. The source register or memory location is not changed.
• Addition/Subtraction: Adding to or subtracting from the value already in a register.
• Shifting/Rotating: Shifting or rotating the bits in a register to the right or left. Important for multiplication and division.
• Testing: Testing if a register value is zero, positive, negative, or too large.

Test your knowledge about the core functions and components of the CPU. This quiz covers key elements such as the Control Unit, Program Counter, and registers. Perfect for students learning about computer architecture.
