| 20080215875 | Method and apparatus for establishing safe processor operating points - A system and method is provided for establishing safe processor operating points. Some embodiments may include a tamper resistant storage element that stores information regarding one or more operating points of an adjustable processor operating parameter. Some embodiments may further include an element to determine what the current processor operating point is of the operating parameter, and an element to compare the current operating point of the operating parameter with the stored information. | 09-04-2008 |
| 20090024799 | Technique for preserving cached information during a low power mode - A technique to retain cached information during a low power mode, according to at least one embodiment. In one embodiment, information stored in a processor's local cache is saved to a shared cache before the processor is placed into a low power mode, such that other processors may access information from the shared cache instead of causing the low power mode processor to return from the low power mode to service an access to its local cache. | 01-22-2009 |
| 20090132844 | Method, Apparatus, and System for optimizing Frequency and Performance in a Multi-Die Microprocessor - With the progress toward multi-core processors, each core is can not readily ascertain the status of the other dies with respect to an idle or active status. A proposal for utilizing an interface to transmit core status among multiple cores in a multi-die microprocessor is discussed. Consequently, this facilitates thermal management by allowing an optimal setting for setting performance and frequency based on utilizing each core status. | 05-21-2009 |
| 20090199024 | METHOD, APPARATUS AND SYSTEM TO DYNAMICALLY CHOOSE AN AOPTIMUM POWER STATE - Some embodiments of the invention include an apparatus and method for dynamically choosing an optimum power state. In some embodiments, the optimum power state may be determined from historical information about the various power states that any of the embodiments of the apparatus or a system equipped with embodiments of the apparatus or operating embodiments of the method may encounter. Some embodiments may generate registers to maintain information regarding the various power states. In some embodiments, power management logic may determine the optimum power state based upon this information. Other embodiments are described. | 08-06-2009 |
| 20100077232 | Processor power consumption control and voltage drop via micro-architectural bandwidth throttling - A method, device, and system are disclosed. In one embodiment the method includes supplying a processor with a first voltage. The method also includes allowing the processor to function within an enhanced processor halt state at the first voltage. The first voltage is a voltage below the lowest compatible voltage for the enhanced processor halt state. The method allows the processor to execute instructions upon waking from the enhanced processor halt state at the first voltage by throttling a maximum throughput rate of instructions being executed in the processor. | 03-25-2010 |
| 20100083021 | Voltage stabilization for clock signal frequency locking - A processor, system, and method are disclosed. In an embodiment, the processor includes a first site and a second site. There is a link to transmit a voltage stabilization signal from the second site to the first site. In the first site voltage correction logic can dynamically modify a voltage supplied to the first site and second site. In the second site there is logic to assert the voltage stabilization signal. After asserting the voltage stabilization signal, the second site is granted at least a window of time in which the supplied voltage to the second site does not change. | 04-01-2010 |
| 20100146311 | Method and Apparatus for a Zero Voltage Processor Sleep State - Embodiments of the invention relate to a method and apparatus for a zero voltage processor sleep state. A processor may include a dedicated cache memory. A voltage regulator may be coupled to the processor to provide an operating voltage to the processor. During a transition to a zero voltage power management state for the processor, the operational voltage applied to the processor by the voltage regulator may be reduced to approximately zero and the state variables associated with the processor may be saved to the dedicated cache memory. | 06-10-2010 |
