Can anyone briefly describe the components of a computer system based on von Neumann s design ideas?

According to Feng. According to Neumann's mind, a computer consists of five parts: combinator, memory, controller, and input and output

Combinator: a component that performs arithmetic and logical operations, the data of which is given in binary format, which can be removed from memory or from an input device, and the result of the operation is either written to memory or output by an output device;

Controller: Coordinates the proper functioning of the entire computer system. It mainly includes instruction registers, instruction decoders and timing controllers and other components, combinators and controllers are generally called processing components CPU, which is the core component of the computer;

Input and output parts: including various input and output devices and corresponding input and output interfaces.

A computer based on the von Neumann architecture must have the following functions:

Send the required programs and data to the computer.

Must have the ability to memorize programs, data, intermediate results, and final computing results for a long time.

Ability to complete various arithmetic, logical operations and data transmission and other data processing capabilities.

It can control the program direction according to the needs and control the coordinated operation of the various parts of the machine according to the instructions.

Ability to output processing results to users as required.

In order to accomplish these functions, a computer must have five basic building blocks, including:

You can go to the Internet to look it up, a lot.

Von Neumann's design ideas can be briefly summarized in the following three points:

1) The computer should be equipped with five basic components, including the combinator, memory, controller, input and output devices.

2) Binary should be used inside the computer to represent instructions and data. Each instruction typically has an opcode and an address code. where the opcode indicates the nature of the operation, and the address code indicates the address of the operand in memory.

3) Send the programmed program into the internal memory, and then start the computer to work, the computer can automatically take out the instructions and execute the instructions one by one without the intervention of the operator. Feng&s226;The most important thing about Neumann's design thought is that he explicitly puts forward the concept of "program storage", and his whole design idea is actually the concretization of the concept of "program storage".

The von Neumann system refers to the von Neumann architecture. The main points of the von Neumann architecture are: the number system of the computer adopts binary; The computer should execute in the order of the program.

This theory of von Neumann is known as the von Neumann architecture. Features of the von Neumann architecture:

1) The data and instructions processed by the computer are all represented by binary numbers.

2) Sequential execution of the program.

During the operation of a computer, the program to be executed and the data to be processed are first stored in the main memory (memory), and when the computer executes the program, it automatically and sequentially takes out the instructions from the main memory and executes them one by one.

3) Computer hardware consists of five parts: combinator, controller, memory, input device and output device.

Summary. Von Neumann structure.

Combinator: Arithmetic Logic Unit (ALU) is a component of the computer to process data, including arithmetic operations (addition, subtraction, multiplication, division, etc.) and logical operations (and, or, not, XOR, comparison, etc.).

Controller: responsible for taking out instructions from memory and decoding instructions; According to the requirements of the instruction, according to the chronological order, it is responsible for sending control signals to other components to ensure that all components work in harmony and complete various operations step by step. It is mainly composed of instruction registers, decoders, program counters, operation controllers, etc.

Memory: A part of a computer that memorizes or stages data. The entire information in the computer, including the original input data. Intermediate data that has undergone preliminary processing as well as useful information that has been processed at the end of the process are stored in memory.

Input device: A device that inputs information to a computer. It is an important human-machine interface that converts incoming information, including data and instructions, into a binary generation that can be recognized by a computer.

What are the components of a von Neumann computer system, and how does it work?

The von Neumann computer is a computer based on the von Neumann structure, which is mainly composed of five parts: controller, memory, combinator, input device and output device. Pictured: Von Neumann structure-combinator:

The arithmetic logic unit (ALU) is a part of the computer that processes data, including arithmetic operations (addition, subtraction, multiplication, division, etc.) and logical operations (AND, OR, NOT, XOR, comparison, etc.). Controller: responsible for taking out instructions from memory and decoding instructions; According to the requirements of the instruction, according to the chronological order, it is responsible for sending control signals to other components to ensure that all components work in harmony and complete various operations step by step.

It is mainly composed of instruction hidden rubber registers, decoders, program counters, operation controllers, etc. Memory: A part of a computer that memorizes or stages data.

The entire information in the computer, including the original input data. Intermediate data that has undergone preliminary processing as well as useful information that has been processed at the end of the process are stored next to the storage stove. Input Devices:

A device that feeds information into a computer. It is an important human-machine interface that converts incoming information, including data and instructions, into a binary generation that can be recognized by a computer.

Von Neumann's design ideas are embodied in three aspects:

1. The computer uses binary logic.

2. Program storage and execution.

3. A computer consists of five parts (combinator, controller, memory, input device, output device), and this set of theories is known as the von Neumann architecture.

Von Neumann structure of computer systems.

It is made up of five basic components:

1. Combinator.

It is used to complete various arithmetic operations and logical operations.

and data processing such as data transmission.

2. Controller: used to control the execution of the program, it is the brain of the computer. Combinators and controllers make up the processors of a computer.

cpu）。The controller is stored in the memory according to that.

and a program counter controls the execution of instructions. The controller has the ability to judge and select different workflows based on the calculation results.

3. Memory: used to memorize programs and data, such as memory. Programs and data are in binary.

**The form is stored in memory indiscriminately, and the location of the storage is determined by the address.

4. Input device: used to input data or programs into the computer, such as: mouse, keyboard.

5. Output device: display the processing results of data or programs to users, such as monitors and printers.

The five basic components are controlled by commands and data is transferred between different components.
