Abstract
In an embodiment, an electronic device includes one or more audio codec nodes and one or more audio application nodes, which communicate audio information with each other over a communications bus. The communications bus is a packet-based bus, in an embodiment. Power is selectively controlled to selected ones of the audio codec node and the audio application nodes, based on whether or not a node is of use at a particular time.
