Example apparatus disclosed herein compare one or more audio latency characteristics with one or more audio latency requirements in response to detection of an audio silence event, the audio latency characteristic(s) associated with at least one of a hardware layer or a device layer of an audio stack of a compute device, the audio latency requirement(s) associated with an application. Disclosed example apparatus also control a device layer of the audio stack to enter a device layer low power mode in response to a first determination that the audio latency requirement(s) is/are met by the audio latency characteristic(s). Disclosed example apparatus further control a hardware layer of the audio stack to enter a hardware layer low power mode in response to the first determination and a second determination that an operation condition for entry into the hardware layer low power mode is met.

Audio stack power control based on latency

In one embodiment, a processor includes: a plurality of cores to execute instructions; a power controller to control power consumption of the plurality of cores, the power controller to receive network traffic metadata from a classifier and control the power consumption of at least one of the plurality of cores based at least in part on the network traffic metadata; and a hardware feedback circuit coupled to the plurality of cores, the hardware feedback circuit to determine hardware feedback information comprising an energy efficiency capability and a performance capability of at least some of the plurality of cores based at least in part on the network traffic metadata. Other embodiments are described and claimed.
