Apparatus and Method to Dynamically Expand Associativity of A Cache Memory

In an embodiment, a processor includes at least one core, a cache memory, and a cache controller. Responsive to a request to store an address of a data entry into the cache memory, the cache controller is to determine whether an initial cache set of the cache memory and corresponding to the address...

Beschreibung
Zusammenfassung:	In an embodiment, a processor includes at least one core, a cache memory, and a cache controller. Responsive to a request to store an address of a data entry into the cache memory, the cache controller is to determine whether an initial cache set of the cache memory and corresponding to the address has available capacity to store the address. Responsive to unavailability of capacity in the initial cache set, the cache controller is to generate a first alternate address associated with the data entry and to determine whether a first cache set corresponding to the first alternate address has available capacity to store the alternate address and if so to store the first alternate address in the first cache set. Other embodiments are described and claimed.
