Abstract
A multi-dimension engine, connected to a system TLB, generates sequences of addresses to request page address translation prefetch requests in advance of predictable accesses to elements within data arrays. Prefetch requests are filtered to avoid redundant requests of translations to the same page. Prefetch requests run ahead of data accesses but are tethered to within a reasonable range. The number of pending prefetches are limited. A system TLB stores a number of translations, the number being relative to the dimensions of the range of elements accessed from within the data array.
