WebThe TLB acts as a cache of the page table for the entries that map to physical pages only. The TLB contains a subset of the virtual-to-physical page mappings that are in the page … WebEach TLB entry maps an adjacent pair of pages. As the result the virtual address of a TLB entry needs to be aligned to twice the page size. This is an unusual restriction and may …

The TLB is accessed using the virtual page number. If the TLB hits, it returns the corresponding physical page number. WebNov 8, 2002 · In other words, when a TLB entry is inserted into a translation register, both the TLB entry and the translation register name (e.g., itr1) have to be specified. In contrast, insertion into a translation cache requires specification of only the TLB entry—the hardware then picks an existing entry and replaces it with the new one. Figure 4.30. nty airport
