A system and method for visual demonstration of 8051 single-chip microcomputer principle

Abstract

The invention provides a system and a method for performing visualization demonstration on a 8051 singlechip principle and belongs to the field of experiment teaching instruments. The system comprises a demonstration rack, a three-screen display, a panel, a PC (Personal Computer) machine, a unit model and a wire, wherein the three-screen display and the panel are fixedly arranged on the demonstration rack; the panel is provided with a sliding chute and an end hole which are used for fixing the unit model and the wire; the back surface of the panel is provided with a power supply and a communication bus; the PC machine comprises a three-screen output display card and a communication interface and is connected with the three-screen display and the panel; the top surface of the unit model is provided with a touch screen LCD (Liquid Crystal Display). The method comprises the following steps: sequentially displaying a sequence diagram, a structure chart and a source code of a 8051 soft core on the three-screen display; constructing a command execution path model on the panel by use of the unit model and the wire; and demonstrating the singlechip principle in a virtuality and reality combination manner. The system can be used for solving the problem that an existing experiment instrument has difficulty in comprehensively and visually demonstrating the internal components and working principle of the 8051 singlechip in real time, and can be used as an experiment teaching instrument for the singlechip principle and application courses in colleges.

Description

technical field [0001] The invention relates to a system and method for visual demonstration of 8051 single-chip microcomputer principles, belonging to the field of experimental teaching instruments. Background technique [0002] Most of the current single-chip microcomputer experimental teaching instruments are based on the architecture of "single-chip microcomputer + various interfaces and peripherals", highlighting the rich application functions of single-chip microcomputers, but there are bottlenecks in demonstrating the internal composition and working principles of single-chip microcomputers. Students can only understand and use single-chip microcomputers from the perspective of programming models, and lack a deep understanding of the internal structure and working principles of single-chip microcomputers, which leads to the defect of "soft and hard" in the knowledge structure of professionals. With the rapid development of integrated circuit technology, the future cor...

Problems solved by technology

These codes are all open source, but their functions are different from those of the Intel standard 8051 core, such as the cycle mismatch of assembly instructions, and the cutting of module functions.

There is a certain technical threshold to fully master the principle of 8051 single-chip microcomputer by learning these IP cores, which is not suitable for beginners to learn
