Find the basic structure diagram of the microcomputer system?

From the perspective of system composition, a microcomputer system should include two major parts: hardware system and software system. Hardware system of microcomputer The hardware of microcomputer is composed of microprocessor, system bus, internal memory, I/O interface and external equipment, etc. Its composition block diagram is shown in the figure below.

The computer system consists of two parts: computer hardware and software. Hardware includes central processors, memory and external devices, etc.; software is the running program of the computer and the corresponding documents.The computer system has the functions of receiving and storing information, quickly calculating and judging according to the program, and outputting processing results, etc.

Hardware is the foundation for software establishment and reliance, and software is the soul of the computer system. Figure 2-1 Composition of microcomputer system Computer hardware system Computer hardware system is composed of five basic functional components: operator, controller, internal memory, input device and output device, as well as interface, auxiliary equipment, etc.

Microcomputer bus hardware structure diagram The main module diagram of the computer host The motherboard (Mainboard or Motherboard, abbreviated as M/B) is the largest rectangular circuit board in the computer host.

How to draw a system structure diagram?

1. Determine the structure and components: First, determine the components of the architecture to be drawn. This may include various modules, components, subsystems, services, etc. Determine the relationship and connection: Determine the relationship and connection of the components. This may include dependencies, interfaces, data flows, etc.

2. The first step: search for the "Yitu Diagram" software on the web page, or visit the online version of the Yitu Diagram web page and open the software. Start drawing. Step 2: Create a new system structure diagram. Just search for "system structure diagram" directly in the search bar, and then select a suitable template in the example template library below, and click to open and use.

3. Just represent all parts of the system, including the controlled object and the control device, in a box.

4. System function nodeThe composition drawing method is as follows: determine the functional requirements: draw the functional modules according to the requirements and determine the functions of each module. Determine the relationship between modules: Determine the relationship between modules according to functional requirements and draw a flowchart between modules.

5. The drawing method of the system composition box is as follows: First, you need to write the text on it and add borders and background lines. Special symbols are inserted into the special symbols. Use the simulation of MATLAB software to draw a block diagram of the system.

Just search for "system structure diagram" directly in the search bar, and then select a suitable template in the example template library below, and click to open and use.

3. The method of making architecture diagrams is as follows: First, we need to sort out the data according to the rules from large to small. For example, for the company's position chart to be produced, we need to sort all positions by department and level. Only in this way can we ensure the logic and intuitiveness of the architecture diagram.
