Abstract

An application processor, an electronic device and a method of operating the application processor are provided. The application processor may include a host processor, a voice trigger system and an audio subsystem electrically connected to a system bus. The voice trigger system may be configured to perform a voice trigger operation and to issue a trigger event. The audio subsystem may be configured to replay an audio output stream through an audio interface. A direct bus may be configured to provide a communication path between the voice trigger system and the audio subsystem during a barge-in condition in which the voice trigger operation and the replay of the audio output stream are performed together. The application processor may be configured to generate compensated trigger data by performing an echo cancellation with respect to microphone data received from a microphone, and the voice trigger system may be configured to perform the voice trigger operation during the barge-in condition based on the compensated trigger data.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2018-0009496 filed with the Korean Intellectual Property Office (KIPO) on January 25, 2018, the contents of which are hereby incorporated by reference in their entirety. technical field [0002] Example embodiments relate generally to semiconductor integrated circuits, and more particularly, to an application processor including a low power voice trigger system with a direct path to voice barge, an electronic device including the application processor, and an application processor for operating the application processor. device method. Background technique [0003] Some electronic devices may include voice-based or sound-based intelligent interfaces. One advantage of such a speech-based or sound-based intelligent interface is that the user can interact with the device in a hands-free manner without operating or even looking at the device. Hands-free operation can be particularly beneficial when a pe...
