page virtual memory 中文意思是什麼
page virtual memory
解釋
頁面虛擬存儲器-
Adopting the method of top - down, the virtual memory is divided into memory mange related unit ( segment unit and page unit ) and protection mode related unit ( protection test unit, debug test unit and exception detect unit ). data buses and control bused are designed separately for all of the units. vhdl codes are written and simulated
Amex86的虛擬存儲器採用自頂向下的設計方法，把虛擬存儲器劃分為地址管理相關單元（又包括分段單元和分頁單元） 、保護模式相關單元（又包括保護測試單元、調試異常單元利異常檢測單元等） ，分別確立其數據通路和控制通路，完成了vhdl的編碼和模擬工作，通過測試程序模擬驗證了其功能的正確性並測定了基本性能。 -
Page swap, virtual memory
虛記憶頁調換 -
Figure 1 illustrates how virtual pages in a process s address space are mapped to physical page frames in memory
圖1說明了進程地址空間中的虛擬頁如何映射到內存中的物理頁幀。 -
4 ) this thesis presents two pc - based streamline visualization methods for large unstructured grids : memory - mapped file method ( mmfm ) and multithread out - of - core method ( mtom ). mmfm constructs streamlines like in - core methods through mapping large data file into virtual ram, and reduces page faults by organizing data in spatial blocks
4 ）針對大規模非結構網格，提出了兩種基於pc的流線可視化方法：內存映像文件方法（ mmfm ）和多線程out - of - core方法（ mtom ） 。 -
Maps the virtual pages accessed by applications to real page frames in main memory
，將應用程序訪問的虛擬頁映射到主存中的實際頁幀。 -
Inlining functions, for example, eliminates the overhead of function calls, but inlining too much code may make your program so large that the number of virtual - memory page faults increases
例如，內聯函數可消除函數調用的系統開銷，但是內聯太多代碼可能使應用程序很大，致使虛擬內存頁的錯誤數增加。 -
Another potentially more efficient virtual memory approach would be to use the page modification dirty bits in the old generation heap to identify blocks to scan for objects containing old - to - young pointers
另一種可能更有效的虛擬內存方法是在老一代堆中使用頁修改臟位（ page modification dirty bit ） ，以確定為找到包含老到年輕指針的對象時要掃描的塊。 -
To improve virtual memory management mechanism, the kernel code is amended to avoid the incertitude cause by page scheduling, thus the responding speed is effectively improved. the irrationality of linux scheduling mechanism is also analyzed, and the methods and models such as to fortify scheduling occasion and adopt double kernel are also proposed to improve it
在虛擬內存管理機制的改進上，作者從操作系統內核入手，對內核代碼進行修改，去除了由於頁面調度帶來的響應不確定性，有效的提高了系統的響應速度；在實時調度上，分析了linux現有調度機制的不合理性，提出了增加調度時機、採用雙內核等方法，給出了改進的模型。 -
That field of the total address ( virtual or physical ) that defines the page containing the desired address in apaged memory system
在分頁存儲器系統中，虛或實總地址中定義包含所需地址的頁面的欄位（中的內容） 。
