    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: For one disclosed embodiment, a plurality of processor cores may be on a semiconductor die. The processor cores may have at least one corresponding temperature sensor. Circuitry on the semiconductor die may generate thermal event indications based on sensed temperatures from multiple temperature sensors of multiple processor cores. A thermal event indication may indicate that a sensed temperature exceeds a temperature point. Central management logic on the semiconductor die may receive thermal event indications based on sensed temperatures from multiple temperature sensors of multiple processor cores. The central management logic may modify operation of one or more of the processor cores in response to a thermal event indication. Other embodiments are also disclosed.
