Patent ID: 7596384

Claim:
A method, comprising: receiving a request from an audio codec to establish a connection between an application subsystem and a communication subsystem of a wireless terminal; and creating the connection between the audio codec of the application subsystem and the communication subsystem in response to said request, the connection formed over a single subsystem interface coupling an application processor in the application subsystem to a communication processor in the communication subsystem through a transport mechanism and operable to provide a control path coupling the application processor and the communication processor, the connection further operable to transport audio information between the application subsystem and the communication subsystem over the single subsystem interface to provide a data stream path; wherein creating the connection includes binding one of a plurality of channels to a direct memory access chain to transport audio information by direct memory access between the application subsystem and the communication subsystem via the direct memory access chain, the direct memory access chain including a first direct memory access block in the application subsystem and a second direct memory access block in the communication subsystem.
