摘要
嵌入式操作系统VxWorks作为关键应用领域的杰出代表,具有微内核、高可靠性、实时性强、可裁减等特点,日益成为嵌入式系统课程体系中重要的教学内容之一。从课程教学的实践性需求出发,首先,设计了面向Vxworks的两级实验教学内容体系(基本实验和综合实验);其次,基本实验的设计从模块级出发,包括开发环境、任务处理、数据通信、显示处理等基本环节;综合实验内容在前者基础上给出系统级的综合实验设计;最后,设计了一个综合显示模拟仪表系统实验,以此巩固课程教学知识和提升学生对于嵌入式系统技术开发的综合能力。
As an outstanding embedded operating system of critical application fields,VxWorks has the characteristics of micro-kernel,high reliability,hardreal-time performance,and can be reduced.It has become one of the important teaching contents in embedded system curriculum system.Based on the practical needs of teaching,first designs a two-level experimental teaching content system(basic experiment and comprehensive experiment)for Vxworks,in which the basic experiment design starts from the module level,including the development environment,task processing,data communication,display processing and other basic links;and then the comprehensive experimental content is provided.Finally,a comprehensive display simulation instrument system experiment is designed to consolidate the teaching knowledge and enhance the students’comprehensive ability for embedded system technology development.
