摘要:
An apparatus and method are described for performing history-based prefetching. For example a method according to one embodiment comprises: determining if a previous access signature exists in memory for a memory page associated with a current stream; if the previous access signature exists, reading the previous access signature from memory; and issuing prefetch operations using the previous access signature.

In an embodiment, a processor includes a core to execute instructions, where the core includes a clock generation logic to receive and distribute a first clock signal to a plurality of units of the core, a restriction logic to receive a restriction command and to reduce delivery of the first clock signal to at least one of the plurality of units. The restriction logic may cause the first clock signal to be distributed to the plurality of units at a lower frequency than a frequency of the first clock signal. Other embodiments are described and claimed.

In an embodiment, a processor has a core to execute instructions which includes a first cache memory, a clock generation logic to receive and distribute a first clock signal to a plurality of units of the core, and a core activity monitor logic to monitor activity of the core and, responsive to a miss in the first cache memory, to send a first restriction command to cause the clock generation logic to reduce delivery of the first clock signal to at least one of the units to a first frequency less than a frequency of the first clock signal. Other embodiments are described and claimed.
摘要:
A processor includes a core, a memory subsystem, a predictor module, and a memory rename module. The predictor module may include a first logic to identify a dependency between a store instruction and a load instruction, and a second logic to assign a memory renaming (MRN) register to the store instruction and the load instruction based on the identified dependency. Further, the memory rename module may include a third logic to copy, based on the assigned MRN register, information in a first logical register associated with the store instruction directly to a second logical register associated with the load instruction.
摘要:
A method includes combining at least two 3-D models, given the positions of the models and constraint areas of the models that should not be changed by the combination. The combining includes generating a weighted graph representation of the models at least in a transition volume and including at least a portion of the constraint areas and finding a minimum cut which separates the weighted graph into two cut graphs representing cut versions of the models.
