The present invention includes a novel audio recognition peripheral system
and method. The audio recognition peripheral system comprises an audio
recognition peripheral a programmable processor such as a microprocessor
or microcontroller. In one embodiment, the audio recognition peripheral
includes a feature extractor and vector processor. The feature extractor
receives an audio signal and extracts recognition features. The extracted
audio recognition features are transmitted to the programmable processor
and processed in accordance with an audio recognition algorithm. During
execution of the audio recognition algorithm, the programmable processor
signals the audio recognition peripheral to perform vector operations.
Thus, computationally intensive recognition operations are advantageously
offloaded to the peripheral.
