There are several parts of the CPU and what parts are included in the CPU

The CPU generally consists of a logical operation unit, a control unit, and a storage unit.

2, controller and combinator.

The CPU mainly consists of two main components, the combinator and the controller. Combinators are mainly composed of arithmetic logic units and registers, and controllers are control units.

**The CPU (Central Processing Unit) is a very large-scale integrated circuit, which is the computing core and control unit of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software.

**The processor mainly consists of combinators (ALUs, arithmetic logic units) and caches, as well as buses that enable the data, control and state between them. Together with internal memory and input and output (IO) devices, it is known as the three core components of electronic computers.

The two main components that make up a computer CPU are:Combinatorsand controllers.

The CPU includes arithmetic logic components and registers.

components and control parts. CPU from memory or cache memory.

, put the instruction into the instruction register, and translate the instruction to encode. It decomposes the instruction into a series of micro-operations, and then issues various control commands to execute a series of micro-operations, so as to complete the execution of an instruction.

An instruction is a basic command for a computer that prescribes the type of operation to be performed and the number of operands. An instruction consists of one or more bytes, including an opcode field, one or more fields about the operand address, and some status words and feature codes that characterize the state of the machine. Some directives also contain the operand itself directly.

History. CPU appeared in the era of large-scale integrated circuits, and the iterative update of processor architecture design and the continuous improvement of integrated circuit technology have promoted its continuous development and improvement. From the beginning of the dedication to mathematical calculations to the widespread use of general-purpose computing, from 4-bit to 8-bit, 16-bit, 32-bit processors, and finally to 64-bit processors.

From vendor incompatibilities to the emergence of different instruction set architecture specifications, CPUs have been evolving at a rapid pace since their inception.

The CPU is made up of two parts: the combinator and the controller.

1. The combinator consists of an arithmetic logic unit (ALU), an accumulator, a state register, a general register group, etc. The basic functions of the arithmetic logic operation unit (ALU) are the four operations of addition, subtraction, multiplication, and division, the logical operations such as and, or, non, and XOR, as well as the operations of shifting and complementing.

When calculating the operation of the hail machine, the operation of the combinator and the operation of the provenance class are determined by the controller. The combinator processes data from memory; The processed result data is usually sent back to memory or temporarily stored in a combinator. Together with the Control Unit, it forms the core part of the CPU.

2. The controller is divided into a combination of logic controller and microprogram controller, and the two controllers have their own advantages and disadvantages. The combinatorial logic controller is cumbersome to design, complex in structure, and once the design is complete, it can no longer be modified or expanded, but it is fast.

The microprogram controller is convenient in design, simple in structure, easy to modify or expand, and only needs to reprogram the corresponding microprogram to modify the function of a machine instruction;

To add a machine instruction, simply add a microprogram to the control memory, however, it is by executing a microprogram. The specific comparison is as follows: The combined logic controller, also known as the hard-wired controller, is composed of logic circuits and relies entirely on hardware to realize the function of instructions.

The CPU consists of arithmetic logic components, register components, and control components.

Knowledge extension: **The processor (CPU, central processing unit) is a very large-scale integrated circuit, which is the computing core and control unit of a computer. Its function is mainly to interpret computer instructions and process data in computer software.

The central processor mainly consists of combinators (ALUs, arithmetic logic units) and caches, as well as buses that enable the data, control, and state of the connections between them. Together with internal memory and input and output (IO) devices, it is known as the three core components of electronic computers.

The performance of a computer is largely determined by the performance of the CPU, which is mainly reflected in the speed at which it runs programs. Performance metrics that affect the running speed include parameters such as CPU operating frequency, cache capacity, silver calendar, instruction system, and logical structure.
