摘　　要：针对微机原理与接口技术课程抽象难讲、实验受到硬件环境制约等问题,在教学及实验中引入虚拟仪器平台,以有效的提高教学及实验效果。利用LabVIEW高效直观的开发环境,对各种接口芯片进行功能仿真,构建出直观的基本输入/输出实验界面,实验者通过接连图分析出端口地址,在前面板上输入相应地址,选择相应指令,可直观的看到实验结果,对深入理解基本输入/输出操作、端口地址译码,以及无条件输入输出方式都有很好的帮助,可作为实验箱实际实验的辅助平台。利用LabVIEW设计的虚拟平台可以有效的丰富教学方法与手段,对提高学生实际动手能力、培养学生创新能力有着积极的意义,在实际教学中也取得了不错的效果。In order to solve the problems in the teaching of Computer Principle and Interface Technology,a virtual instrument platform is proposed in this paper to improve the effects of both theoretical and practical teaching.Using the efficient and intuitive development environment of Lab VIEW,the paper conducts the function simulation onvarious interface chips respectively and constructs intuitive input/output experiment interfaces.The experimenter can analyze the port address through a circuit diagram,enter the appropriate address on the front panel,select the appropriate instructions,and then directly achieve the experiment result.The whole experience can help students thoroughly understand the basic input/output operation,port address decoding and the unconditional input/output.The system can be used as an auxiliary platform for practice in experimental boxes.The virtual platform designed through Lab VIEW can effectively enrich teaching methods and means,and improve the practical ability and innovation ability of students.Good teaching effects are obtained in practical teaching.
