Abstract
A translation look-aside buffer (TLB) is described. The TLB may include a memory populated with pointers to collections (e.g., tables) of virtual-to-physical address translations. The memory may be populated by, for example, a page fault logic in response to resolving a page fault. The TLB may also include a signal logic to receive a virtual address and to selectively provide either a miss signal or a pointer to a collection of virtual-to-physical translations. The signal may provide the miss signal upon determining that the virtual address is not associated with a stored pointer and may provide a pointer upon determining that the virtual address is associated with the pointer.
