From here, you can determine that its objectives are to help minimize both the response time of page faults and to decrease the use of virtual memory where it can.
由此可以看出，它的目标是帮助最大限度地缩短缺页响应时间，并在可能的情况下减少虚拟内存的使用。
Figure 1 illustrates how virtual pages in a process's address space are mapped to physical page frames in memory.

The POWER Hypervisor performs virtual memory management using a global partition page table, and manages any attempt by a partition to access memory outside its allocated limit.
POWER Hypervisor使用全局分区页表执行虚拟内存管理，并管理分区尝试访问超出其分配限制之外的内存的请求。
The POWER5 chip actually supports four virtual memory page sizes: 4KB, 64KB, 16MB, and 16GB.
实际上，POWER5芯片支持四种虚拟内存页面的大小：4KB、64KB、16MB和 16GB。
In the Linux memory manager, page tables keep track of the physical pages of memory that are used by a process, and they map the virtual pages to the physical pages.
在Linux内存管理器中，页表保持对进程使用的内存物理页的追踪，它们将虚拟页映射到物理页。
The Linux kernel operates in a virtual memory mode: for every virtual page there is a corresponding physical page of memory in the system.
Linux内核工作于虚拟内存模式：每一个虚拟页对应一个相应的系统内存的物理页。
The main purpose for large page usage is to improve system performance for high-performance computing applications or any memory-access-intensive application that uses large amounts of virtual memory.
使用大页面的主要目的是，提高高性能计算应用程序或使用大量虚拟内存的任何内存访问密集型应用程序的系统性能。
The VMM has a page-replacement algorithm, which assigns the page frames and determines exactly which virtual-memory pages currently in RAM will have their page frames brought back to the free list.
VMM 提供了一种页面置换算法，该算法用于分配页帧，以及确定应该将当前RAM 中的哪些虚拟内存页面的页帧置换回空闲列表。
Within the Virtual Memory window you will have the C drive (SSD) with no page file set and you should now see the RamDisk listed also.
在虚拟内存窗口中，您将在C硬盘（SSD ） ，没有页面文件设置，您现在应该可以看到该内存磁盘还列出。
Entry consists of the virtual address of the page stored in that real memory location, with information about the process that owns that page.
表项包含真正内存地址的页的虚拟地址，它包括拥有这个页的进程的信息。
Each operating-system process is allocated its own virtual address space — a set of virtual-memory pages that it can read from and write to. Each page can be in one of three states.
每个操作系统进程占用自己的虚拟地址空间，即一组可以读写的虚拟内存页。
Improving virtual memory page replacement can reduce page fault rate, and therefore improve the performance of the system.
改进页面置换算法，可以降低页面失败率，从而有效地提高系统性能。
These virtual addresses are mapped to physical memory by page tables, which are maintained by the operating system kernel and consulted by the processor.
