摘要:
A method includes detecting a trigger condition, and in response to detecting the trigger condition, reducing a voltage applied to a graphics controller component of a memory controller. The reduction in voltage may cause the voltage to be reduced below a voltage level required to maintain context information in the graphics controller component.

摘要:
When a processor in a computer system is placed in a low power mode, power consumption of the computer system may be further reduced by reducing power consumption of one or more components of a memory coupled to the processor and by reducing power consumption of one or more components of a controller device coupled to the memory. The processor and the controller device may share the memory.

摘要:
A novel graphics system including workload detection software is disclosed. The novel graphics system increases the voltage and frequency of the graphics hardware in an integrated graphics chipset, depending on operations performed by the hardware, for either a performance advantage or a power savings advantage.

In one embodiment of the invention, an integrated device is described that employs a mechanism to control power consumption of a graphics memory controller hub (GMCH) through both voltage and frequency adjustment of clock signal received from a clock generator. The GMCH comprises a graphics core and a circuit to alter operational behavior, such as the frequency of a render clock signal supplied to the graphics core. The circuit is adapted to monitor idleness of the graphics core and reduce a frequency level of the render clock signal if the idleness exceeds a determined percentage of time.

Machine-readable media, methods, and apparatus are described to throttle interfaces and/or logic based upon a temperature estimate. Some embodiments may provide thermal effects associated with throttled and non-throttled interfaces to a filter. The filter may update a temperature estimate based upon the provided thermal effects and one or more thermal time constants. Control logic may determine whether to throttle one or more interface based upon the temperature estimate of the filter.

Embodiments of systems, apparatuses, and methods for energy efficiency and energy conservation including enabling autonomous hardware-based deep power down of devices are described. In one embodiment, a system includes a device, a static memory, and a power control unit coupled with the device and the static memory. The system further includes a deep power down logic of the power control unit to monitor a status of the device, and to transfer the device to a deep power down state when the device is idle. In the system, the device consumes less power when in the deep power down state than in the idle state.
摘要:
A processor may operate at a first frequency level for a first time interval. The processor automatically may transition to a sleep state from the first frequency level after the first time interval. Then the processor automatically transitions from the sleep state to the first frequency level after a second time interval. As a result the processor may operate at a reduced power consumption and higher performance.
