A method performed by a processor is described. The method may include identifying a graphics processing unit (GPU) phase of a frame, using said identified GPU phase to obtain frequency scalability information for said identified GPU phase, and determining whether to change a frequency at which a GPU is to draw said frame within said phase based on said frequency scalability information.

Identification of GPU phase to determine GPU scalability during runtime

A memory access management technique is disclosed, one embodiment of which relates to a technique to issue loads to a memory ahead of older store operations corresponding to the same target address. A processor may include load buffer entries having predictor table entries associated therewith, including saturation counters to record history of previous conflicts between loads and stores corresponding to the same target address. A watchdog unit may disable memory disambiguation (MD) if the MD causes too high a misprediction rate for load operation and store operation conflicts. In one embodiment, the MD is disabled if a flush counter value reaches a threshold.

Memory disambiguation techniques using counter ratio to selectively disable load/store conflict prediction

Counter-based memory disambiguation techniques for selectively predicting load/store conflicts

Memory access management techniques are described. More particularly, at least one embodiment of the invention relates to a technique to issue loads to a memory ahead of older store operations corresponding to the same target address. In an embodiment, a load operation may be predicted to not conflict with older pending store operations if a saturation counter corresponding to the load operation is below a threshold value and a maximum rate of mispredictions has not occurred. Other embodiments are also disclosed.
