Abstract:

The traditional experiment course is usually carried out in a specialized laboratory, which could produce undesirable results due to the factors such as time limit and equipment constraints. Therefore, it is very necessary to develop a set of virtual experimental system of computer organization principles. The system was designed for the laboratory equipment in our school. In order to realize this virtual experimental system, the specification of objectoriented technology was followed, UML（Unified Modeling Language） method was adopted for modeling, and the language VC++ was used. The innovation of the system is that the UML based design for functional unit was adpoted, and the complete simulation of the device was realized. After a practical use of 327 students of two grades, the satisfaction rate reached 81%, which laid the foundation of the virtual laboratory in our school.

Key words: virtual experiment, principles of computer composition, unified modeling language(UML)
