    Abstract: A processor can operate in different power modes. In an active power mode, the processor executes software. In response to receiving a halt indication from the software, hardware at the processor evaluates bus transactions for the processor. If the bus transactions meet a heuristic, hardware places a processor core in a lower power mode, such as a retention mode. Because the bus transactions are evaluated by hardware, rather than by software, and the software is not required to perform handshakes and other protocols to place the processor in the lower power mode, the processor is able to place the processor core into the lower power mode more quickly, thereby conserving power.

    Abstract translation: 处理器可以在不同的功率模式下工作。 在有功功率模式下,处理器执行软件。 响应于从软件接收到停止指示,处理器处的硬件评估处理器的总线事务。 如果总线事务满足启发式,则硬件将处理器内核置于较低​​功耗模式下,例如保留模式。 由于总线事务由硬件而不是软件进行评估,并且软件不需要执行握手和其他协议来将处理器置于低功耗模式,处理器能够将处理器内核置于低功耗模式 更快,从而节约电力。

    Abstract: A system may comprise a plurality of processing units, and a control unit and monitoring unit interfacing with the processing units. The control unit may receive requests for transitioning the processing units to respective target power-states, and specify respective target HW power-states corresponding to the respective target power-states. The monitoring unit may monitor operating characteristics of the system, and determine based on operating characteristics whether to allow the processing units to transition to the respective target hardware (HW) power-states. The control unit may be configured to change the respective target HW power-state to a respective updated HW power-state for each processing units for which it is determined that transition to its respective target HW power-state should not be allowed. The control unit may also be configured to infer a common target HW power-state based on the respective target HW power-states of processing units of a subset of the plurality of processing units, when the processing units of the subset of the plurality of processing units share at least one resource domain.

    Abstract: Power management logic maintains memory in a computer system in the self refresh state during a power savings state in which power is removed from the memory controller. A memory control circuit, separate from the power management logic, controls the memory during other operational modes. The power management logic maintains the system memory in the self refresh state by driving memory control signal(s) at appropriate values during the power savings state.

    Abstract: The maximum performance state available to a processor in a computer system, in terms of operating frequency and/or voltage, changes according to thermal criteria. When the temperature increases above a predetermined threshold, the maximum performance state available is reduced. Multiple temperature thresholds may be utilized providing for a gradually reduced maximum performance state as temperature increases. When the temperature returns to a lower level, the maximum performance state available is increased. Changing the maximum available performance state according to temperature provides for more gradual reduction in performance as temperature increases, which results in higher average system performance as temperature increases. Thus, a more gradual reduction in performance is provided while still maintaining a high speed rating of the processor in more ideal conditions. In normal operating conditions, high processor performance is provided, while slightly reduced performance is provided in abnormal operating conditions.

    Abstract: A processor can operate in three different modes. In an active mode, a first voltage is provided to the processor, where the first voltage is sufficient to allow the processor to execute instructions. In a low-power mode, a retention voltage is provided to the processor. The processor consumes less power in the retention mode than in the active mode. In addition, the processor can operate in a third mode, where a voltage is provided to the processor sufficient to allow the processor to process cache messages, such as coherency messages, but not execute other normal operations or perform normal operations at a very low speed relative to their performance in the active mode.

    Abstract: Method and apparatus for automatically adjusting the brightness level of an LCD based on the ambient lighting conditions of the environment in which the LCD is being operated are disclosed. In a preferred embodiment, a photodetector located proximate the front of the LCD generates to brightness control circuitry signals indicative of ambient lighting conditions. These signals are correlated to predetermined automatic brightness control values for use in controlling the brightness level of the LCD. Once the ambient light signals have been used automatically to set the brightness level of the LCD, user-selection of a different brightness level, either higher or lower, will override the automatic brightness control setting. In an alternative embodiment, a first photodetector is located proximate the front of the LCD and a second photodetector is located proximate the back of the LCD. In this embodiment, the brighter ambient condition is used to control the brightness level of the LCD. In another alternative embodiment, the brightness control circuitry comprises some form of artificial intelligence for "learning" a user's preferred brightness level, or range of brightness levels, in various ambient lighting conditions.
