| 中文摘要 | 分析WINE虚拟机响应缓慢的根源,提出平台抽象层(PAL)的概念,设计并实现了基于PAL的进程虚拟机Elavm。在Linux,Windows和WinCE上,完成了Elavm PAL的硬件抽象模块、操作系统抽象模块和设备驱动抽象模块。其中,操作系统抽象模块实现了一个通用虚拟内核、一组高效的系统调用和一种基于共享内存的"忙等待"进程间同步方法。测试表明,基于PAL的进程虚拟机,其平均响应时间仅为类WINE虚拟机的千分之一。; WINE virtual machine is analyzed and the reasons of its slow server are pointed out.The concept of Platform Abstraction Layer(PAL) is proposed,and a process virtual machine Elavm is designed and implemented.On Linux,Windows and WinCE,the hardware abstraction,operating system abstraction and device driver abstraction within Elavm PAL are finished.The operating system abstraction includes a general virtual kernel,a set of system calls with high performance and a "busy-wait" inter-process synchronization mechanism based on shared memory.Test results show the average responding time of PAL-based virtual machines is about one thousandth of WINE-like virtual machines. |
