中文摘要	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.
