  • Method and system for dynamic cache partitioning using address remapping
    Patent number: 9489309
    Abstract: A system and method for providing a cache virtual partition to a data structure that includes receiving, at an address remapping device, a cache-check request including a memory address including bits, identifying, using a virtual partition table, the virtual partition by determining that the memory address falls within a data structure memory address range, obtaining a copy of virtual partition bits which include a portion of the bits, appending the copy of the virtual partition bits to the memory address, rewriting the virtual partition bits to obtain rewritten virtual partition bits corresponding to the virtual partition, and generating a remapped memory address by replacing the virtual partition bits with the rewritten virtual partition bits. The remapped memory address includes the copy of the virtual partition bits and rewritten virtual partition bits. The method also includes transmitting a remapped cache check request including the remapped memory address to the cache.
