英汉例句

• the processor does this through the use of a page fault interrupt.

  处理器通过缺页中断来进行这个操作。

• the data address that caused the page fault problem was 0x00(dar 0000000000000000).

  引起页面错误的数据地址为0x00（dar0000000000000000）。

• 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。

• 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.

  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。

• because the cost of a page fault is high, it is desirable that a garbage collector properly manage locality of reference.

  因为页面错误的成本很高，所以垃圾收集器正确管理引用的区域性 (locality)是很必要的。

• any other access to unmapped memory triggers a page fault that results in a segmentation fault.

  任何其他访问映射的内存，结果在一个分割故障触发页面错误。

• the dsisr (data storage interrupt status register) indicates why the page fault could not be resolved.

  dsisr（数据存储中断状态寄存器）表示页面错误无法解决的原因。

• an instruction storage interrupt is a page fault on an instruction fetch.

  指令存储中断通常是指在取出指令时发生页面错误。

• if it cannot find it there, a page fault occurs, and this signals the kernel to bring more pages into ram from disk.

  如果无法在ram 中找到这个页面，则出现一次缺页，这指示内核从磁盘中装载更多的页面到ram 中。

• there is a problem of counting the page fault rate in the paging system. this paper analyzes the cause of the difference for the output in different textbooks.

  在单段式虚拟存储器-请求式分页系统中，涉及到缺页中断次数的计算问题。从虚拟存储器的基本原理出发，分析了各种教材中有关计算结果不同的主要原因。

• the dsirr (data storage interrupt reason register) indicates the type of page fault that has occurred.

  dsirr（数据存储中断原因寄存器）表示发生的页面错误的类型。

• when a page fault is taken on a file due to an instruction fetch, only the non-computational file transitions to the computational state.

  如果某个文件因为指令取出发生了缺页，那么会将非计算性文件转换为计算性状态。

• however, if a page fault cannot be resolved while in kernel mode or if a page fault occurs when interrupts are disabled, then a dsi will cause a system crash.

  然而，如果页面错误不能够在内核模式下解决，或者在禁用中断情况下出现页面错误，那么dis将造成系统崩溃。

• for any file system, data may be paged, since such a page fault can always be resolved eventually by retrieving the correct contents off disk.

  对于任何文件系统，数据应当被分页，因为这样一个页面错误总是能够通过从硬盘上恢复而最终被正确的解决。

• if the page fault is due to an instruction fetch (meaning the process was trying to load an instruction from the page to execute), the kernel marks the file as computational.

  如果是由于指令取出而导致的缺页（意味着该进程正在尝试加载来自该分页的指令，以便进行相关操作），那么内核会将该文件标记为计算性的。

• this event is called a page fault and is detected by hardware (the mmu), and then managed by firmware after a page fault interrupt occurs.

  这个事件被称为一个页面错误并被硬件（mmu）删除，出现页面错误中断后该事件由防火墻管理。

• kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.

  系统内核所使用的内存空间通过特权码（privilegedcode，2级或者更低）来标记，以防止用户模式的程序访问到内核空间而发生页面错误。

• only when a page fault is hit, for example, because the accessed page has been swapped out to disk, does the ppe receive an interrupt.

  例如，只有在由于所访问的页面已经被交换到磁盘上而发生页面失效的情况时，ppe才会接收到一个中断。
