Apparatus and methods for processing of media signals

A method for efficiently processing audio and video data at a processing device comprising a central processing unit (CPU) and a graphics processing unit (GPU), the method comprising:

• receiving a request for processing audio data;
• determining whether the GPU is in a first operational state;
• determining whether the GPU is in a first availability state;
• when the GPU is determined to be in the first operational state and the GPU is determined to be in the first availability state, transmitting the audio data to the GPU for processing;
• and
• when the GPU is not in both the first operational state and the first availability state, causing the audio data to be processed at the CPU.

A non-transitory computer readable memory medium comprising program instructions for delegating processing of audio data from a central processing unit (CPU) to a graphic processing unit (GPU) of a processing apparatus, wherein the program instructions are executable to:

• write a first plurality of tasks to a queue, wherein the queue is associated with the GPU, wherein the tasks are executable by the GPU;
• identify a second plurality of tasks relating to processing the audio data, wherein each of the CPU and the GPU is capable of executing the second plurality of tasks;
• determine whether the second plurality of tasks should be written to the queue, wherein the determining is based at least in part on a level of completion of the performance of the first plurality of tasks by the GPU;
• in response to determining that the second plurality of tasks should be written to the queue, write the second plurality of tasks to the queue.
