Abstract

Hardware Cycle Based Memory Residency implementation over traditional time based, or software based method addresses cache rehit probabilities and the overhead of scanning and freeing memory, and having pages stay resident in memory for long periods of time. This invention may be better for performance by relying on the hardware cycle counter rather than the system clock or software methods for freeing memory pages.
