Abstract: Systems and methods for essentially continuous audio flow for Internet of Things (IoT) devices during power mode transitions contemplate an audio bus, such as a SOUNDWIRE audio bus, to maintain an audio stream during a clock transition without having to tear down the audio stream as a new clock becomes active on the audio bus. By preserving the audio stream during such a transition, gaps in the audio are avoided resulting in better performance and end user experience.

Abstract: Full-duplex memory access systems and methods for improved quality of service (QoS) are disclosed. In one aspect, a primary bus owner will evaluate an output from a secondary bus owner when the primary bus owner takes control of the bus to determine if the secondary bus owner has data to send to the primary bus owner and/or is in the midst of a bulk data transfer. If the evaluation determines that there is still data to be transferred, the primary bus owner may refrain from draining an internal register unless a full word is present in the register. By reducing memory access for a partial word in the register, QoS may be improved.
