Abstract
In an embodiment, a TLB is partitioned into regions. The TLB may be set associative, and each section may include a portion of the locations in each way of the set associative memory. The TLB may reserve at least one of the sections for access by a subset of the request sources that use the TLB. For requests from the subset, the reserved section may be used and a location in the reserved section may be allocated to store a translation for a request from the subset that misses in the TLB. For requests for other request sources, the non-reserved section or sections may be used. In one embodiment, each way of the reserved section may be assigned to a different one of the request sources in the subset.
