The central unit, usually referred to as the central processing unit (CPU), is the core component of the computer system, responsible for executing the instructions stored in memory and completing various calculation and control tasks. Here is a detailed explanation of the central unit (CPU) :
1. Main functions
Program control: The 07KT97H3 CPU controls the execution order of the program by executing instructions.
Operation control: The CPU generates the operation signal of each instruction, and sends these signals to the corresponding components to control the corresponding components to operate according to the functional requirements of the instruction.
Time control: The CPU controls the time of various operations, including the time, duration and time order of the operation signal during the execution of instructions.
Data processing: 07KT97H3 CPU performs arithmetic operations and logic operations on the data to meet the needs of users.
Two, components
The CPU mainly consists of the following components:
Arithmetic unit: including arithmetic logic unit (ALU), accumulation register, data buffer register and state condition register, etc., used to complete various arithmetic and logic operations of the computer.
Controller: responsible for removing instructions from memory, decoding the instructions, and controlling other components to perform corresponding operations.
Register bank: A small storage device consisting of a number of single-word registers used to store data and instructions.
Internal bus: The channel that connects the components inside the CPU to transmit data and instructions.
Third, the working principle
The working principle of CPU is mainly based on two ways: instruction driven and data driven. The specific process includes:
Data input: 07KT97H3 The external device of the computer converts the data entered by the user into signals and sends them to the input port of the CPU, which converts these signals into binary data and stores them in memory.
Instruction fetching and decoding: The CPU takes the instruction from memory and stores it in the instruction register, then decodes the instruction, converting it into an operation that can be performed by the hardware.
Execution of operations: After the decoding is completed, the CPU executes the corresponding operations, including arithmetic operations, logical operations, data movement, etc., and is completed in the execution unit of the CPU.
