APPLICATION PROCESSOR SUPPORTING INTERRUPT DURING AUDIO PLAYBACK ELECTRONIC DEVICE INCLUDING THE SAME AND METHOD OF OPERATING THE SAME

摘要

An application processor includes a system bus, a host processor, a voice trigger system, and an audio sub-system. The host processor is electrically connected to the system bus. The voice trigger system is electrically connected to the system bus and the voice trigger system performs a voice trigger operation based on a trigger input signal provided through a trigger interface to generate a trigger event. The audio sub-system is electrically connected to the system bus and the audio sub-system processes an audio stream played and recorded through an audio interface. The audio sub-system receives an interrupt signal through the audio interface while audio is played through the audio interface. While playing the audio, by supporting the interrupt through the audio interface, the audio may be played with low power and the recognition rate of the voice trigger operation may be increased.
