摘　　要：以Alpha处理器作为实现平台,将系统仿真软件QEMU移植到Alpha上,使基于x86结构的Linux操作系统可以运行在系统虚拟机中,实现Alpha处理器与x86程序的兼容。对该虚拟机进行性能测试,通过统计代码膨胀率,找出制约虚拟机性能的指令类型,为虚拟机性能优化工作提供参考数据。This paper takes Alpha processor as the platform,and migrates the system simulation software of QEMU to Alpha platform,so that the virtual machine on system can perform Linux operating system based on x86 architecture to achieve Alpha processor compatible x86 applications.Performance test is performed on virtual machine.Through the statistics of code inflation rate,a restricted virtual machine performance instruction type,is found to provide reference for virtual machine performance optimization.

关 键 词：Alpha处理器 动态二进制翻译 系统虚拟机 系统级仿真 代码膨胀率
