Abstract
A system and method are provided for optimizing the translation of virtual addresses into physical addresses for a graphics address remapping table (GART). In the system and method, a translation look-aside buffer cache has a plurality of translation look-aside buffer entries. Each translation look-aside buffer entry is operable to buffer information which may be accessed for use in translating a virtual address into a physical address. A least recently used pointer circuit is operable to point to a translation look-aside buffer entry buffering information least recently used in the translation look-aside buffer cache. During operation, updates to the least recently used pointer circuit may be pipelined with corresponding accesses to the translation look-aside buffer cache.
