Abstract
An application processor is provided. The application processor includes a system bus, a host processor, a voice trigger system and an audio subsystem that are electrically connected to the system bus. The voice trigger system performs a voice trigger operation and issues a trigger event based on a trigger input signal that is provided through a trigger interface. The audio subsystem processes audio streams through an audio interface. While an audio replay is performed through the audio interface, the application processor performs an echo cancellation with respect to microphone data received from a microphone to generate compensated data and the voice trigger system performs the voice trigger operation based on the compensated data.
