20150095586 | STORING NON-TEMPORAL CACHE DATA - Embodiments herein provide for using one or more cache memory to facilitate non-temporal transaction. A request to store data into a cache associated with a processor is received. In response to receiving the request, a determination is made as to whether the data to be stored is non-temporal data. A predetermined location of the cache is selected; the location to which storing of the non-temporal data is restricted to a predetermined location, in response to determining the data to be stored is non-temporal data. The non-temporal data is data that is not accessed within a predetermined period of time. The non-temporal data is stored into the predetermined location. | 04-02-2015 |
