在 Intel 手册上,对于分页结构的命名,由高到低分别是:5 级页映射表(Page Map Level 5,PML5)、4 级页映射表(Page Map Level 4,PML4)、页目录指针表(Page-Directory-Pointer Table,PDPT)、页目录(Page Directory,PD)以及页表(Page Table,PT)。对应的页结构项(Paging Structure Entry),分别为:PML5E( PML...
在linux下的分页结构为:pgd→p4d→pud→pmd→pte→page(4k)。 1.2.14-LEVEL PAGING 4-LEVEL PAGING下还支持4K/2M/1G几种page模式,下面是其分页结构(paging structure)的层次图: 1、4-LEVEL PAGING 4k-page(pgd→pud→pmd→pte→page(4k)) 2、4-LEVEL PAGING 2M-page(pgd→pud→pmd→page(2M)) 3、4-...
2. Page Table Creation: The operating system keeps track of the mapping between logical addresses (used by the program) and physical addresses (used by the memory) in a data structure called the page table. When a program is loaded into memory, the page table is created, which contains the...
Typical TLB sizes are well known for different page sizes (4KB, 2MiB, etc) however there is very little known about the page table cache sizes (E.g. Paging-Structure Caches from Sec 4.10.3 Vol 3A of the Intel Software Developer Manual). In addition to the TLB and PDE, a pro...
The course provides knowledge of the principles of and how one can implement abstractions of hardware virtualisation of resources and timetabling of assignments; mainly as regards execution, memory and persistent storage. The structure of an operating system is studied to increase the knowledge of these...

structure, called the page directory. The page directory thus either can be used to tell you where a page of the page table is, or that the entire page of page table contains no valid pages. The page directory, in a simple two-level page table, contains one entry per page of the pag...

Operations and structure of the terminal and the paging control for the paging as described above are elucidated below. FIGS. 2A and 2B illustrate operations of a terminal in a broadband wireless communication system according to an exemplary embodiment of the present invention. Referring to FIGS. ...
It is noted that the present invention can be applied to any access network structure having a paging function for paging a terminal device from a cellular network. The description of the preferred embodiment is only intended to illustrate the present invention. The preferred embodiment may thus be...
