Further aspects may include determination of a second processor performance characteristic associated with a second workload, determination of a second processor performance state for the second workload based on the performance characteristic, determination of a similarity between the first performance characteristics and the second performance characteristics, determination of a cluster comprising the first workload and the second workload, and association of a third processor performance state with the cluster, wherein the third processor performance state is identical to the first processor performance state and to the second processor performance state. | 03-26-2009 |
| 20090248994 | MEMORY RANK BURST SCHEDULING - A method, device, and system are disclosed. In one embodiment the method includes grouping multiple memory requests into multiple of memory rank queues. Each rank queue contains the memory requests that target addresses within the corresponding memory rank. The method also schedules a minimum burst number of memory requests within one of the memory rank queues to be serviced when the burst number has been reached in the one of the plurality of memory rank queues. Finally, if a memory request exceeds an aging threshold, then that memory request will be serviced | 10-01-2009 |
| 20110264938 | METHOD AND SYSTEM FOR DETERMINING AN ENERGY-EFFICIENT OPERATING POINT OF A PLATFORM - A method and system for determining an energy-efficient operating point of the platform or system. The platform has logic to dynamically manage setting(s) of the processing cores and/or platform components in the platform to achieve maximum system energy efficiency. By using the characteristics of the workload and/or platform to determine the optimum settings of the platform, the logic of the platform facilitates performance guarantees of the platform while minimizing the energy consumption of the processor core and/or platform. The logic of the platform identifies opportunities to run the processing cores at higher performance levels which decreases the execution time of the workload and transitions the platform to a low-power system idle state after the completion of the execution of the workload. Since the execution time of the workload is reduced, the platform spends more time in the low-power system idle state and therefore the overall system energy consumption is reduced. | 10-27-2011 |
| 20110320839 | MEMORY POWER MANAGEMENT VIA DYNAMIC MEMORY OPERATION STATES - Described herein are techniques for dynamic memory frequency/voltage scaling to augment existing memory power management techniques and further improve memory power efficiency.

| 20110320846 | ADAPTIVE MEMORY FREQUENCY SCALING - Methods and apparatuses for adaptive memory operational state management. A memory performance parameter is determined for at least a portion of a memory system. The memory performance parameter is compared to one or more threshold values. An operating frequency of the memory system can be modified based on results of the comparison of the memory performance parameter and the one or more threshold values. | 12-29-2011 |
| 20120017099 | METHOD AND APPARATUS TO LIMIT MEMORY POWER - In one embodiment, the present invention includes a power manager to receive a memory power usage value, to determine an available power based at least in part on a power budget and the memory power usage value, and to change a memory power state based at least in part on the available power, wherein the memory power state comprises a memory frequency and a memory voltage. Other embodiments are described and claimed. | 01-19-2012 |
