Abstract
A processing system includes a hardware synchronizer to synchronize the transmission of audio data from multiple I2S controllers of a processing system to one or more audio codecs. In some embodiments, each of the I2S controllers receives audio data from one or more audio data sources and stores the audio data at a buffer associated with the controller. The hardware synchronizer initiates synchronized transmission of the audio data from the plurality of controllers to the one or more codecs in response to the buffer associated with each controller being filled to a predetermined level. In some embodiments, until the controllers begin transmission of the audio data, the controllers transmit mute (null) data to the one or more codecs such that the one or more codecs receives a frame start followed by null data for each frame.
