Abstract: Methods and apparatus for processing media signals. In one embodiment, a data processing device processes fixed and variable rate data using a first and second processing unit. The processing comprises real-time processing of audio/video signals by a graphics processing unit (GPU) and/or central processing unit (CPU). The processing units process data efficiently by establishing one processor as always processing variable rate data, and using one or more schemes for determining processor will process fixed rate data. A shared memory enables the processors to communicate with one another in order to determine which will process the fixed rate data. In one scheme for determining which of the processors will process the fixed rate data the second processor need merely be unlocked. In another embodiment, the second processor must be unlocked and immediately available.

Abstract: A method and apparatus for processing data samples utilizes a channel map populated by device descriptor, or by an application program interface. Packet processing code loops through all of the samples contained in a packet while incrementing through a channel map and steering table without having to look up a table to determine in what audio buffer the sample is to be stored or read. Additionally, the present invention utilizes a stride map, so the audio subsystem knows how many samples to skip in order to reach the next sample frame. The present invention can be used for handling received packets as well as forming packets to send over a bus.

Abstract: Audio jack optical modules that may have a reduced size. Various examples may provide an optical module for an audio jack where a driver circuit is omitted from the optical module and instead placed either elsewhere in the audio jack or separately outside the audio jack. In some examples, the driver may be integrated with a logic circuit, such as a coder-decoder (CODEC) or other logic circuit. Other examples may provide an optical module for an audio jack where a lens for a light-emitting diode is omitted. In some examples, a higher-power light-emitting diode may be used. These light-emitting diodes may be strong enough to provide a requisite amount of light to a detector in, or associated with, an audio plug.
