| 摘 要： | 为了进行软硬件的并行开发,同时也提高内核态驱动的开发与测试效率,借助于开源虚拟机,实现了模拟的电子模块系统并行总线(QBUS)仿真接口。出于开源与效率考虑决定采用虚拟机QEMU。基于QEMU的模拟设备的实现有两个方面的难点:1)QEMU虚拟机的工作原理及其I/O框架,2)模拟设备的之间的通信方式。在研究了QEMU虚拟机的工作原理及其I/O框架基础上,设计并实现了模拟QBUS设备之间,基于socket设备组通信模型,模拟QBUS设备与物理设备之间,基于虚拟设备转发的通信模型。有效地解决了模拟设备之间,模拟设备与物理设备之间数据传输对应用程序不透明的问题。

| Abstract: | Implemented the emulation of QBUS equipment based on open source virtual machine QEMU, considering of improving the development and testing efficiency in kernel ring , and performing parallel development of software and hardware .This paper focused on two part： the understanding of QEMU＇s I/O framework and the communication between two emulated device. Based on the research of the QEMU virtual machine and its I/O framework , this paper designed and implemented a device group communication model through socket between two simulated QBUS device and a model of forwarding packet through virtual device between simulated device and physical device. |
