I would like to share with you who put forward the principle of stored program control in the computer network. I believe most people don't know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. let's learn about it!

The person who proposed the principle of stored program control is "von Neumann". Von Neumann, a famous American Hungarian mathematician, summarized the experience in the development of ENIAC and put forward the principle of stored program control. The main point of stored program control is that the number system of the digital computer is binary, and the computer should be executed according to the program order.

The person who proposed the principle of stored program control is "von Neumann".

In the mid-1930s, Von Neumann boldly proposed to abandon the decimal system and use binary production as the basis of the digital computer system. At the same time, he also said that the calculation program is compiled in advance, and then the computer will perform the numerical calculation in the order in which people make the calculation in advance.

Von Neumann and his colleagues designed a complete prototype of the modern computer and identified the five components and basic working methods of the stored program computer. Von Neumann's design idea is regarded as a milestone in the history of computer development and marks the real beginning of the computer era.

Von Neumann successfully applied his theory to the design of computers. The computer manufactured according to this principle is called von Neumann structure computer. The first von Neumann computer in the world was the EDSAC developed by Cambridge University in 1949, which absorbed von Neumann's design ideas. Because of his outstanding contribution to modern computer technology, Von Neumann is also known as "the father of computers". The principle of stored program control is also called von Neumann principle.

working principle

First of all, the program and data are sent to memory through the input and output device. General memory is divided into many [2] storage units, each with an address number, so that programs and data are stored in a certain order, and the memory is divided into several areas. for example, there is a special program area and a data area for data storage. Secondly, the execution program must start with the first instruction and then be executed one by one.

In general, it is executed from small to large according to the order in which the address number is stored, and the order of execution is changed only when conditional transfer instructions are encountered. Each instruction is executed through three steps: the first step is to send the instruction from memory to the decoder, which is called fetch; the second step, the decoder decomposes the instruction into opcodes and operands to generate corresponding control signals and send them to various electrical components; the third step is to perform the corresponding operation. This process is controlled by the electronic route to achieve automatic and continuous work. At run time, the controller takes out the instructions stored in the memory according to the address order (accessing the instructions in the address order), then analyzes the instructions, executes the function of the instructions, and transfers to the transfer address when the transfer instruction is encountered, and then accesses the instructions in the address order.

Theoretical essentials

The idea of storing a program-describe the calculation process as a program composed of many commands in a certain order, and then input the program and data into the computer, and the computer processes the stored programs and data, and then outputs the results.

The main point of stored program control is that the number system of the digital computer is binary, and the computer should be executed according to the program order.

According to the stored program control structure, the computer must have the following functions:

1. Send the required programs and data to the computer

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

3. The ability to complete data processing such as arithmetic, logical operation and data transmission.

4. it can control the direction of the program according to the need, and can control the coordinated operation of all parts of the machine according to the instructions.

5. Be able to output the processing results to the user as required.

In order to perform the above functions, a computer must have five basic components, including:

1. Input devices for inputting data and programs

2. Memory of programs and data

3. Arithmetic unit that completes data processing.

4. The controller for the execution of the control program

5. The output device for outputting the processing results.
