TLB is the cache holding the mapping information from the virtual address to the physical page in memory .

在Windows中，您可以使用CreateThread（）来创建线程，创建的线程在调用进程的虚拟地址空间中运行。

In Windows , you can use CreateThread () to create a thread to execute under the virtual address space of the calling process .

所用到的技术和所涉及的知识主要有：PE文件格式、逆向分析技术、进程及其虚拟地址空间、windows消息、钩子技术、键盘虚拟技术和内存代码的动态注入和修改等。

Knowledges and techniques mainly involved are PE File Format , reverse analyzing , process and its virtual memory , the windows message , hook technology , the virtual key technology and injecting and modifying the code dynamically in other process etc.

其次，EPT技术则使客户机的虚拟地址到宿主机的物理地址转换变得简单。

Secondly , the EPT technology can easily convert the virtual address of guest OS to physical address of host OS .

为了提高CPU的速度和更有效的管理物理内存，一般都采用转换查找缓冲器（TLB）将虚拟地址转换为物理地址。

In order to optimize performance , including speed and the usage of its memory , CPU usually hires a Translation Lookaside Buffer ( TLB ) to translate the virtual address into physical address .

地址变换缓冲器TLB（TranslateLook-asideBuffer）加快了处理器中虚拟地址向物理地址的转换，但地址映射过程往往处于关键路径上。

Translate Look-aside Buffer ( TLB ) accelerates the address transition rate from virtual address to physical address in processor , but the address mapping process is often on the critical path .

如果对当前不在物理内存中加载的虚拟地址进行引用（这是一个页面错误），则会出现DSI错误。

A DSI occurs whenever a reference is made to a virtual address that is not currently loaded in physical memory ( this is a page fault ) .

它只知道自己的虚拟地址空间。

All it knows about is its own virtual address space .

假设我们有一台计算机16位虚拟地址系统

Suppose we 're given a computer with a 16bit virtual address

为这个堆栈保留的虚拟地址空间总数（包括没有提交的范围）

Total virtual address space reserved for this heap ( includes uncommitted ranges )

多个虚拟地址可以指向同一物理地址。

More than one virtual address can refer to the same physical memory location .

为了能同时对虚拟地址空间和他对应的页表都进行分页。

So we can page the virtual address space AND page the page table .

输出中首先给出进程虚拟地址空间的索引

The output begins by showing an index into the virtual address space for the process

实地址就是当禁用了虚拟地址到物理地址的转换时所生成的地址。

The real address is the address generated when virtual to physical address translation is disabled .

有效用户虚拟地址空间

Valid user virtual address space

可用虚拟地址空间。

Available virtual address space .

虚拟地址空间用于存放进程中的一些项目，例如

The virtual address space is used for a number of different items in the process such as

采用格雷码作为地址编码，引入虚拟地址页来产生标志位。

The design makes use of grey code as its address code and generates flag bit by dummy-address-page .

每个用户空间的进程都使用自己的虚拟地址空间，而内核则占用单独的地址空间。

And while each user-space process occupies its own virtual address space , the kernel occupies a single address space .

在计算机程序中，将绝对地址、虚拟地址或设备标识符与符号地址或标号联系起来。

To associate an absolute address , virtual address or device identifier with a symbolic address or label in a computer program .

操作系统维持着一个虚拟地址到物理地址的转换的表，以便计算机硬件可以正确地响应地址请求。

The operating system maintains a table of virtual address-to-physical address translations so that the computer hardware can respond properly to address requests .

一种地址转换方式，其中虚拟地址不通过存储映象进行转换，例如将虚拟地址作为实际地址使用。

A mode where virtual addresses are not transformed through a memory map ; for example , the virtual address is used as an actual address .

操作系统随即更新地址映射，以便被请求的虚拟地址能映射到物理地址。

The operating system updates the mapping of virtual to physical addresses , so that the requested virtual address can be mapped to a physical address .

它把导致页面失效的虚拟地址装入寄存器中，再利用中断句柄来通知操作系统。

The processor will store the virtual address which caused the page fault in a register , and then signal the operating system through an interrupt handler .
