The Virtual Experiment Design of Serial Communication Based on VC++

According to the needs required by experimental teaching, the serial communication interface of the course ¿computer organization principle¿ is analyzed and designed combining with the characters of this course in the paper. Based upon the Tec-xp test box designed by Tsinghua University Computer Factory, Microsoft Visual C++ 6.0 is adopted as the soft development platform. Thinking from the system needs analysis, object-oriented simulation mode is adopted for modeling in this environment. Meanwhile combining with the function characteristic of computer system, the basic theory and methods of discrete event system simulation is applied, which makes the operation is just as the same as on the real equipment. The implementation of the virtual experiment validates the functions of the serial communication interface chip Inter8251, that provides the students a free experiment environment, which also has a good opening-up, generality and practical values.
