Systems and methods for mitigating dram cache conflicts through hardware assisted redirection of pages (harp)

Abstract

Disclosed embodiments relate to systems and methods structured to mitigate cache conflicts through hardware assisted redirection of pages. In one example, a processor includes a translation cache to store a physical to slice mapping in response to a cache conflict mitigation request corresponding to a page; and a cache controller to determine whether the translation cache comprises the physical to slice mapping; determine whether one of a plurality of slices in a translation table comprises the physical to slice mapping if the translation cache does not comprise the physical to slice mapping, the translation table communicably coupled to a non-volatile memory; and if the translation table does not comprise the physical to slice mapping, redirect the cache conflict mitigation request to the non-volatile memory; and allocate a new physical to slice mapping for the page to one of the plurality of slices in the translation table.
