頁映射表 的英文怎麼說
中文拼音 [yèyìngshèbiǎo]
頁映射表
英文
page map table-
The active list contains pages that are currently mapped into memory and have been recently accessed
有效的列表包含當前被映射入內存和最近被獲取了的頁。If there is only a single mapping to the page, then a single pointer called " direct " can be used instead of a linked list
如果只有一個到這個頁的映射,那麼可以用一個叫做「 direct 」的指針來代替鏈表。Instead of traversing the page tables for every process, the memory manager now has, for each physical page, a linked list containing pointers to the page - table entries ptes of every process currently mapping that page
不再是遍歷每個進程的頁表,內存管理器現在為每一個物理頁建立了一個鏈表,包含了指向當前映射那個頁的每一個進程的頁表條目( page - table entries , pte )的指針。For example, a windows odbc application can use the keyword translatedll to indicate the location of db2trans. dll, which contains codepage mapping tables, and the keyword translateoption, which defines the codepage number of the database
例如, windows odbc應用程序可以使用關鍵字translatedll來表示db2trans . dll的位置,該文件包含代碼頁映射表,以及使用關鍵字translateoption來定義數據庫的代碼頁數目。This article outlines a few of the more important changes, including reverse mapping, the use of larger memory pages, storage of page - table entries in high memory, and greater stability of the memory manager
本文列出了一些更重要的改變,包括反向映射( reverse mapping ) 、使用更大的內存頁、頁表條目存儲在高端內存中,以及更穩定的內存管理器。Developerworks, march 2004 details new techniques to improve the use of large amounts of memory, reverse mapping, storage of page - table entries in high memory, and the greater stability of the memory manager
( developerworks , 2004年3月)詳細介紹了用來改進大量內存的使用、映射預留、高端內存中的頁表項的存儲以及內存管理器的穩定性所採用的新技術。If each page - table entry consumes 8 bytes, then that would be 2 mb of overhead for every 1 gb of memory mapped
如果每個頁表條目消耗8個位元組,那些每映射1 gb內存需要2 mb的開銷。In such a situation, every process mapping that same 1 gb of memory would consume its own 2 mb worth of page - table entries
在這種情況下,每個映射到同一塊1 gb內存的進程將為頁表條目付出自己2 mb的代價。For every page mapped by each process, page - table entries must also be created to map the virtual address to the physical address
由於每個頁都要由每個進程映射,必須創建頁表條目來將虛擬地址映射到物理地址。If you have a process that maps 1 gb of memory with 4 kb pages, it would take 262, 144 page - table entries to keep track of those pages
如果您的一個進程要使用4kb的頁來映射1 gb內存,這將用到262 , 144個頁表條目來保持對那些頁的追蹤。Assuming a large page size of 4 mb is used in the same example from above, that same 1 gb of memory could be mapped with only 256 page - table entries instead of 262, 144
假定在前面的中使用頁大小為4 mb的大內存頁,同樣1 gb內存只用256個頁表條目就可以映射,而不需要262 , 144個。However, before they can be swapped out, every single process mapping that page must be found so that the page - table entry for the page in that process can be updated
不過,在它們可以被交換出去之前,必須找到映射那個頁的每一個進程,這樣那些進程中相應頁的頁表條目才可以被更新。Browser defaults, favorites and zonemap scanner, which determines if malware has altered your browser home page, favorites or has added any malicious sites to your trusted sites list
