Briefly, in accordance with one embodiment of the invention, a transport
mechanism provides a digital interface to transfer audio data between an
application subsystem and a communication subsystem in a wireless
terminal such as a cellular terminal. A request from a driver of an audio
codec in the application subsystem may result in the creation of a
logical connection between the audio codec and the communication
subsystem. The communication subsystem may directly transfer the audio
information to memory using a direct memory access operation while
performing an audio operation such as a cellular audio operation on the
audio information. A direct memory access operation may then be utilized
to directly transfer the audio information from memory to a serialized
channel.
