摘　　要：软件仿真实验具有通用、使用灵活、易于维护以及可扩展等优越特性,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。采用开源仿真器QEMU设计了虚拟仿真教学实验,为嵌入式系统操作系统原理、嵌入式系统编程基础、Linux驱动开发以及嵌入式开发等教学内容提供良好支撑。QEMU所具有的开源、多架构支持等特性,为实验教学活动的展开提供了更多、更灵活的选择。将基于QEMU的软件仿真实验与硬件仿真实验有机结合,使得嵌入式系统实验教学设计更加合理有效。Software Emulator based experiments 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. Design virtual simulation experiments based on open source machine emulator QEMU, which would assist teaching of embedded operating system principles, programing techniques, driver implement and overall embedded system development. As free and open source software with multiple architecture support, QEMU provide much more agile options for laboratory teaching. Hardware based and Emulator based experiments could be unifed, which make the laboratory teaching more reasonable and effective.
