Experiment Teaching Case Design of Computer I/O Channel Virtual Simulation

The principle of computer composition is an important basic course for undergraduates majoring in computer science, in which the I/O channel control method in the input/output system is mainly applied to mainframes. However, mainframes that support I/O channel design experiments are expensive, complex and costly to operate and maintain, which makes it impossible to carry out hands-on experiments for large-scale students. In this paper, to break the situation that this part of content is mainly taught through textbook in traditional teaching, we design a virtual simulation experiment of computer I/O channel, which is an effective supplement to the practical teaching of computer composition principle. The experimental case has been applied in computer science and technology, information security and software engineering in Tongji University and other colleges and universities, and has been awarded Chinese national first-class course (Virtual Simulation Class). The experimental system has been opened and shared on Chinese national virtual simulation experiment teaching project sharing service platform ( www.ilab-x.com ).
