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.
Claims28
A method, comprising:
- requesting a connection management endpoint from a driver of an audio codec of an application subsystem;
- creating a connection between an the audio codec of the application subsystem and a communication subsystem in response to said requesting;
- and
- binding a channel to a direct memory access channel to transport audio information between the application subsystem and said communication subsystem.
An article comprising a storage medium having stored thereon instructions that, when executed by a computing platform, result in the transport of audio information between an application subsystem and a communication subsystem by:
- requesting a connection management endpoint from a driver of an audio codec of the application subsystem;
- creating a connection between an the audio codec of the application subsystem and the communication subsystem in response to said requesting;
- and
- binding a channel to a direct memory access channel to transport audio information between the application subsystem and said communication subsystem.
An apparatus, comprising:
- an application subsystem;
- a communication subsystem;
- and
- a digital transporter to transfer audio information between said application subsystem and said communication subsystem;
An apparatus, comprising:
- a communication processor;
- and
- a digital transporter to couple said communication processor to an application processor.
