摘要： A message based power management approach is utilized to provide power management for a multi-processor system. A power management message is received at one processor of the multi-processor system over an input/output communication link that provides input/output access for the processors of the multi-processor system. The power management message includes a power management field encoding a power management state for processors of the multi-processor system. The processor that received the power management message over the input/output communication link sends a power management message to other processors in the multi-processor system over one or more inter-processor communication links encoding the power management state.

摘要： A message based power management system converts legacy signals used in power management, and other signals used to differentiate between power states, to messages sent over a communication link. A system message sent on a communication link includes a field encoding the level of power management for the device receiving the system message. Further, one or more additional signals, separate from the communication link, may be used to indicate when to take action after the power management message has been received.

摘要： An integrated circuit is coupled to a communication link and to a separate signal line and includes programmable registers specifying communication link width and frequency. The integrated circuit responds to a change in the value of the signal line by changing the width and/or frequency of at least a portion of the communication link to the programmed value in response to a change in a logical value of the signal line, without the integrated circuit entering a reset state. The width and/or frequency may be changed during a POST routine or during system operation as part of a power management or other system function while maintaining its operational state.

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： 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.

摘要： 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.
