What is the basic working principle of von Neumann structure computer? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The basic working principle of von Neumann structure computer is mainly divided into storage program and program control. in advance, the instruction sequence that controls how the computer operates [called program] and the original data are transmitted to the computer memory through the input device. each instruction clearly defines the computer from which address to take the number, what operation, and then sent to the address and other steps.

The basic working principle of von Neumann structure computer:

When the computer is running, the first instruction is extracted from the memory, and then the data is taken out of the memory for the specified operation and logic operation according to the requirements of the instruction through the decoding of the controller, and then the results are sent to memory according to the address. Next, the second instruction is taken out and the required operation is completed under the command of the controller. Go ahead according to this. Until the stop order is encountered. The program accesses the same as the data, taking out the instructions step by step according to the order of programming, and completing the operation specified by the instructions automatically is the most basic working principle of the computer. The working principle of von Neumann architecture computer can be summarized into eight words: storage program, program control.

Stored program-compiles the steps of solving the problem into a program (usually made up of several instructions) and stores the program in the computer's memory (refers to main memory or memory)

Program control-A controller that reads instructions from the main memory of the computer and sends them to the computer. According to the functions of the current instructions, the controller controls the whole machine to perform the operations specified by the instructions and complete the functions of the instructions. Repeat this operation until the instruction in the program has been executed.

The characteristics of von Neumann architecture computers are:

1) use a single processing unit to complete the work of calculation, storage and communication.

2) the memory cell is a linear organization with fixed length.

3) the unit of the storage space is directly addressed.

4) using low-level machine language, instructions complete simple operations through opcodes.

5) centralized sequential control of the calculation.

6) the computer hardware system is composed of five parts: arithmetic unit, memory, controller, input device and output device, and their basic functions are defined.

7) data and instructions are represented in binary form.

8) when executing the program and processing the data, the program and data must be loaded into the main memory from the external memory, so that the computer can automatically adjust to fetch instructions from the memory and execute them.

The answer to the question about what is the basic working principle of the von Neumann structure computer is shared here.
