Title:
AUDIO OVER SUBSYSTEM INTERFACE
Document Type and Number:
WIPO Patent Application WO2004054195
Kind Code:
A3
Abstract:
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.
