ABSTRACT:
In some embodiments, a method and apparatus for power performance monitors for low-power program tuning are described. In one embodiment, the method includes the computation of power consumption levels of instructions of an application. Once consumption levels are computed, instruction sequences of the application are identified that exhibit an excess power consumption level. For the identified instruction sequences, the application program is recompiled to reduce power consumption levels of one or more of the identified instruction sequences. Other embodiments are described and claimed.
