MOOC环境下嵌入式系统虚拟仿真平台的实现与应用

Implementation and Application of Virtual Simulation Platform for Embedded System in MOOC Environment

针对在"嵌入式Linux应用与开发实践"MOOC教学过程中嵌入式实验设备无法满足实践环节教学需要,本文采用开源仿真器Qemu构建嵌入式虚拟仿真平台,使MOOC学习者能完成预定实践教学项目。嵌入式虚拟仿真平台具有通用、使用灵活、易于维护以及可扩展等特性,可以有效弥补硬件仿真实验在设备维护、资源占用、成本和实验内容等方面的不足,为MOOC实践教学活动的展开提供了更多的选择。

For in the MOOC course of“Embedded Linux Application and Development Practice”,the embedded test equipment cannot meet the practical teaching needs.This paper enables MOOC learners to complete the scheduled practical teaching projects by establishing an embedded virtual simulation environment based on open source machine emulator QEMU.Embedded virtual simulation environment could be excellent complement to hardware based experiments in the laboratory teaching of Embedded System,in the sense it will well compensate the weak part of hardware experiments due to its versatility,flexibility,maintainability and extendibility.The application results show that the embedded virtual simulation environment is an important guarantee for students'practical teaching and achieves a good teaching effect.
