摘要： An audio noise mitigation approach. For one aspect, a first voltage associated with a first power management state is provided. A signal responsive to an indication associated with at least a first type of periodic exit event is received and responsive to the signal, a transition to a second voltage associated with a second state is initiated, a rate of the transition to the second voltage being slower than a similar voltage transition initiated in response to a non-periodic exit event.

摘要： In one embodiment, a data processing system includes, but is not limited to, a processor, a memory coupled to the processor, and a universal serial bus (USB) controller coupled to the processor and the memory. The USB controller includes a local memory to cache at least one activity descriptor of at least a portion of a periodic schedule having multiple frames stored in the main memory. The USB controller defers to service an active USB device described by one of the activity descriptors until a corresponding frame is scheduled to be serviced subsequently. Other methods and apparatuses are also described.

摘要： An interface between an accelerated graphics port graphics controller (AGP-GC) and a core controller to prevent entry into a low power state from interfering with transfers to or from the AGP-GC that have been requested but not completed. The core controller can communicate to the AGP-GC an intent to enter a low power state, while the AGP-GC can communicate to the core controller the busy status of the AGP-GC. When the AGP-GC receives notice of an intent to enter a low power state, it can stop issuing requests to the core controller. When the core controller detects that the AGP-GC is busy, the core controller can postpone entry into the low power state until the AGP-GC completes any requests that are in progress. In an alternate use of the interface, if the AGP-GC wishes to make a request during a low power state, it can signal the core controller of this need by indicating a busy status, which can trigger the core controller to initiate an exit from the low power state.

摘要翻译： 加速图形端口图形控制器（AGP-GC）和核心控制器之间的接口，以防止进入低功率状态，干扰来自AGP-GC的请求但尚未完成的传输。 核心控制器可以与AGP-GC进行通信，意图进入低功率状态，而AGP-GC可以与核心控制器通信AGP-GC的忙碌状态。 当AGP-GC接收到进入低功率状态的意图时，可以停止向核心控制器发出请求。 当核心控制器检测到AGP-GC正忙时，核心控制器可以推迟进入低功率状态，直到AGP-GC完成任何正在进行的请求。 在接口的替代使用中，如果AGP-GC希望在低功率状态期间发出请求，则可以通过指示忙状态来向核心控制器通知该核心控制器，这可以触发核心控制器发起退出 低功率状态。
