Central Processing Unit (CPU)
- The Central Processing Unit (CPU) acts as the computer's "brain," tasked with processing instructions inputted into the system.
- By processing instructions and executing calculations, the CPU generates output.
CPU Functions
- Fetches instructions from memory: The CPU retrieves instructions from the computer's memory (RAM) based on the program counter, which points to the next instruction to be executed. These instructions are typically fetched from the main memory and loaded into the CPU's instruction register for further processing.
- Decodes the instructions to determine the required operation: Once the instructions are fetched, the CPU decodes them to understand what operation needs to be performed. This involves breaking down the instruction into its opcode (operation code) and operands (data on which the operation is to be performed).
- Executes the operation: After decoding the instruction, the CPU executes the operation specified by the opcode. This may involve arithmetic or logical operations, data manipulation, branching (changing the sequence of instructions), or other tasks depending on the instruction set architecture (ISA) of the CPU.
- Stores the result back in memory or sends it to an output device: After the operation is performed, the CPU may need to store the result back in memory if it's required for further processing or send it to an output device such as a display, storage device, or network interface for user interaction or data persistence.
The CPU Components
The Central Processing Unit (CPU) comprises three primary components:
- Arithmetic Logic Unit (ALU): The ALU is responsible for carrying out arithmetic and logic operations on data. For example, when you perform a calculation on your computer, it's the ALU that executes the mathematical operation.
- Control Unit (CU): The Control Unit manages and coordinates the activities of the computer's other units. It directs the flow of data and instructions within the CPU and to and from other devices.
- Registers: Registers are small, high-speed storage locations within the CPU used to temporarily hold data that is being processed. They play a crucial role in the execution of instructions.
