摘要： Power management approaches for computer systems having one or more processors are disclosed. One power management approach provides hierarchical power management. The hierarchical nature of the power management provided by the invention has various levels of power management such that power consumption of the computer system is dependent upon the amount of work placed on the processing resources of the computer system. Another power management approach pertains to deterministic handshaking provided between a power manager and one or more controller units. The deterministic handshaking provides for more reliable and controllable transitions between power management states which have associated power management taking place in the controller units. The power management approaches are suitable for use with a single-processor computer system or a multi-processor computer system.

摘要： One embodiment of the present invention provides a system that switches between frame buffers which are used to refresh a display. During operation, the system refreshes the display from a first frame buffer which is located in a first memory. Upon receiving a request to switch frame buffers for the display, the system reconfigures data transfers to the display so that the display is refreshed from a second frame buffer which is located in a second memory.

摘要： A controller (or controller chip) providing reduced power consumption without impacting performance is disclosed. The controller monitors activity of components within the controller which require access to a local memory, and then decreases a clocking frequency for a memory interface to the local memory when the monitoring indicates that reduced amounts of activity are present. Following such a decrease in the clocking frequency, when increased amounts of activity are detected, the clocking frequency is increased for high performance operation. The controller thus tailors the clocking frequency for the memory interface in accordance with the amount of activity of these components that require access to the local memory so that overall less power is used by the controller yet the performance is essentially not hindered. In one embodiment, the controller is a graphics controller, as such controllers require access to local memories.

摘要： Apparatus and techniques for awakening bus circuitry from an inactive state as needed are described. The bus circuitry forms part of a computer system and is placed in the inactive state (i.e., shut down) when not needed so as to conserve power. The bus circuitry is associated with a bus and can be awakened out of the inactive state when certain bus events, including resume, connect or disconnect, occur on the bus. The invention is particularly advantageous for computing devices (e.g., portable computers, desktop computers, server computers) where it is desirous to shut down bus circuitry as well as other circuitry (e.g., microprocessor) when not needed so as to reduce power consumption.

摘要： A thermal manager has a digital filter whose input is to receive raw temperature values from a sensor and whose output is to provide processed or filtered temperature values according to a filter function that correlates temperature at the sensor with temperature at another location in the device. The thermal manager has a look-up table that further correlates temperature at the sensor with temperature at the other location. The look-up table contains a list of processed temperature sensor values, and/or a list of temperatures representing the temperature at the other location, and their respective power consumption change commands. The thermal manager accesses the look-up table using selected, filtered temperature values, to identify their respective power consumption change commands. The latter are then evaluated and may be applied, to mitigate a thermal at the other location. Other embodiments are also described and claimed.
