Abstract
A system with a prefetch address generator coupled to a system translation look-aside buffer that comprises a translation cache. Prefetch requests are sent for page address translations for predicted future normal requests. Prefetch requests are filtered to only be issued for address translations that are unlikely to be in the translation cache. Pending prefetch requests are limited to a configurable or programmable number. Such a system is simulated from a hardware description language representation.
