Abstract
Systems and method for memory management units (MMUs) configured to automatically pre-fill a translation lookaside buffer (TLB) with address translation entries expected to be used in the future, thereby reducing TLB miss rate and improving performance. The TLB may be pre-filled with translation entries, wherein addresses corresponding to the pre-fill may be selected based on predictions. Predictions may be derived from external devices, or based on stride values, wherein the stride values may be a predetermined constant or dynamically altered based on access patterns. Pre-filling the TLB may effectively remove latency involved in determining address translations for TLB misses from the critical path.
