Filed:

Mar 4, 2008

Appl. No.:

12/042181

Inventors:

Nidish Kamath - Placentia CA, US
Eddie L. T. Choy - Carlsbad CA, US
Prajakt Kulkarni - San Diego CA, US
Samir K Gupta - San Diego CA, US
Stephen Molloy - San Diego CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G10H 1/00

US Classification:

84626, 84662, 381 61

Abstract:

This disclosure describes techniques that make use of a plurality of hardware elements that operate simultaneously to service synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises storing audio synthesis parameters generated for one or more audio files of an audio frame, processing a first audio synthesis parameter using a first audio processing element of a hardware unit to generate first audio information, processing a second audio synthesis parameter using a second audio processing element of the hardware unit to generate second audio information, and generating audio samples for the audio frame based at least in part on a combination of the first and second audio information.

Abstract:

This disclosure describes techniques that make use of a waveform fetch unit that operates to retrieve waveform samples on behalf of each of a plurality of hardware processing elements that operate simultaneously to service various audio synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises receiving a request for a waveform sample from an audio processing element, and servicing the request by calculating a waveform sample number for the requested waveform sample based on a phase increment contained in the request and an audio synthesis parameter control word associated with the requested waveform sample, retrieving the waveform sample from a local cache using the waveform sample number, and sending the retrieved waveform sample to the requesting audio processing element.
