Abstract

Techniques are disclosed for prefetching cache lines. One technique includes dispatching a virtual processor and recording a first set of addresses associated with one or more cache lines used by the virtual processor. The technique also includes redispatching the virtual processor and recording a second set of addresses associated with one or more cache lines used by the virtual processor. The technique further includes comparing the first set of addresses with the second set of addresses to determine one or more common addresses between the first set and the second set. The technique includes placing the one or more common addresses into a memory. Finally, the technique includes redispatching the virtual processor.
