The first thing that "Virtual Memory" does is that it abstracts the physical address space of the machine.
第一件事“虚拟内存”不在于它抽象机器的物理地址空间。
Assign a different physical address space to each process, ensuring an efficient protection against addressing errors.
分配不同的物理地址空间给每个进程，确保了有效的保护以避免地址错误。
More specifically, the invention relates to utilizing a physical address space for a graphics processor that includes address locations in both system memory and graphics local memory.
更具体来说，本发明涉及将包括系统存储器以及图形本地存储器中的地址位置的物理地址空间用于图形处理器。
A native memory leak or excessive native memory use will cause different problems depending on whether you exhaust the address space or run out of physical memory.
本机内存泄漏或本机内存过度使用会造成各种问题，这取决于您是耗尽了地址空间还是用完了物理内存。
Note that as shown here, a process may have a large address space, but it is sparse, meaning that small regions (pages) of the address space refer to physical memory through the page tables.
注意这里的显示，进程可能有一个大的地址空间，但是很少见，就是说小的地址空间的区域(页面)通过页表指向物理内存。
Regions in a process's virtual address space can be mapped to physical memory, to a file, or to any other addressable storage.
进程的虚拟地址空间中的区域可被映射到物理内存、文件或任何其他可寻址存储。
Although reserving chunks of the address space will not exhaust physical resources, it does prevent that memory from being used for other purposes.
虽然保留地址空间块不会耗尽物理资源，但它确实能防止内存用于其他目的。
If you have enough physical memory and address space, you can allow the leak to continue on the basis that you will restart your application before the process address space is exhausted.
如果您有足够的物理内存和地址空间，您可以允许泄漏继续，但必须在进程地址空间耗尽之前重新启动应用程序。
This does not mean the kernel USES that much physical memory, only that it has that portion of address space available to map whatever physical memory it wishes.
这并不意味着系统内核能够肆无忌惮的使用物理内存，系统内核只能使用其管辖的虚拟地址空间所对应的物理内存。
Figure 1 illustrates how virtual pages in a process's address space are mapped to physical page frames in memory.
图1说明了进程地址空间中的虚拟页如何映射到内存中的物理页帧。
When running on a system with more process address space than physical memory, a memory leak or excessive use of native memory will force the OS to swap out some of the virtual address space.
在进程地址空间大于物理内存的系统中，内存泄漏或本机内存过度使用会迫使操作系统提供一些虚拟地址空间。
We can map requests from logical to logical, logical to physical (as above) or from one address space to another.
我们可以如下方式来映射请求：逻辑到逻辑、逻辑到物理(如上所述)以及一个地址空间到另一个地址空间。
The memory addresses in the address space allow the agent to access the memories in the physical RAM.
在内存空间中的内存地址允许代理访问物理ram中的内存。
How does kernel know, which pages in the virtual address space correspond to a swapped out physical page frame?
如何知道哪些页面的内核，在虚拟地址空间对应于一个换出的物理页帧？
At initialization, a maximum address space is virtually reserved but not allocated to physical memory unless it is needed.
在初始化的时候，一个最大的地址空间被保留，但是仅在需要的时候才会分配物理地址。
Secondly, lazy management of virtual address space and management of two-layer-cached physical memory are analyzed.
随后详细分析怠惰的虚地址空间管理、两级缓冲的物理内存管理；
The whole point of a virtual memory system is that you can have a virtual address space that's much bigger than the amount of physical memory on the computer.
一个虚拟内存系统的全部重点就是：你可以拥有一个虚拟的地址空间，它比计算机上的物理内存总量还要大。
This does not mean the kernel USES that much physical memory, only that it has that portion of address space available to map whatever physical memory it wishes.
这并不意味着内核使用多少物理内存，只知道它的地址空间映射的物理内存，它希望的那部分。
The MSI memory location is a physical bus address, so it must be translated to virtual address space both on device and host.
MSI的内存位置的物理地址，所以它必须转换为对设备和主机的虚拟地址空间。
The free list contains pages of physical memory that are not associated with any address space of VM object.
可用内存包含不同VM对象联系在一起任何地址空间物理内存的页。
The free list contains pages of physical memory that are not associated with any address space of VM object.
