| 41. | Hence, the TLB is used to reduce the time taken to access the memory locations in the page table method.
|
| 42. | A page table was also originally four kilobytes in size and contained 1, 024 page table entries ( PTE ).
|
| 43. | A page table was also originally four kilobytes in size and contained 1, 024 page table entries ( PTE ).
|
| 44. | The page table, generally stored in main memory, keeps track of where the virtual pages are stored in the physical memory.
|
| 45. | Page tables make it easier to allocate additional memory, as each new page can be allocated from anywhere in physical memory.
|
| 46. | Now, each of these smaller page tables are linked together by a master page table, effectively creating a tree data structure.
|
| 47. | The current Main Page table of contents ( TOC ) is pretty serviceable for much of the current content of Wikipedia.
|
| 48. | The Page table ( generally loaded in memory ) keeps track of where the virtual pages are loaded in the physical memory.
|
| 49. | This method uses two memory accesses ( one for the page table entry, one for the byte ) to access a byte.
|
| 50. | The invention of the page table let the processor operate on arbitrary pages anywhere in RAM as a seemingly contiguous logical address space.
