Abstract
A processing system includes memory management software responsive to a translation lookaside buffer miss. The memory management software updates translation lookaside buffer information based on one or more missed virtual addresses. Entries of a first translation lookaside buffer are updated by the memory management software with information corresponding to the missed virtual addresses if memory page size information for the missed virtual addresses meet a first criterion. Entries of a second translation lookaside buffer are updated by the memory management software with information corresponding to the missed virtual addresses if memory page size information for the missed virtual addresses meet a second criterion. The first and second criterion may correspond to first and second memory page sizes supported by the respective translation lookaside buffers.
