Abstract
An application processor includes a system bus, as well as 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 that are replayed or recorded through an audio interface, and receives an interrupt signal through the audio interface while an audio replay operation is performed through the audio interface.
Claims20
An application processor, comprising:
- a system bus;
- a host processor electrically connected to the system bus;
- a voice trigger system electrically connected to the system bus, wherein the voice trigger system is configured to perform a voice trigger operation and issue a trigger event based on a trigger input signal provided through a trigger interface;
- and
- an audio subsystem electrically connected to the system bus, wherein the audio subsystem is configured to process audio streams that are replayed or recorded through an audio interface,
- wherein the trigger interface is disabled while an audio replay operation is performed through an output pad of the audio interface, and
- wherein the audio subsystem receives an audio input signal through an input pad of the audio interface and the voice trigger system performs the voice trigger operation based on the audio input signal while the audio replay operation is performed simultaneously through the output pad of the audio interface.
An electronic device, comprising:
- an application processor;
- and
- at least one audio input/output device, wherein the application processor comprises:
- a system bus;
- a host processor electrically connected to the system bus;
- a voice trigger system electrically connected to the system bus, wherein the voice trigger system is configured to perform a voice trigger operation and issue a trigger event based on a trigger input signal provided through a trigger interface;
- and
- an audio subsystem electrically connected to the system bus, wherein the audio subsystem is configured to process audio streams that are replayed or recorded through an audio interface,
- wherein the trigger interface is disabled while an audio replay operation is performed through an output pad of the audio interface, and
- wherein the audio subsystem receives an audio input signal through an input pad of the audio interface and the voice trigger system performs the voice trigger operation based on the audio input signal while the audio replay operation is performed simultaneously through the output pad of the audio interface.
A method of operating an application processor, comprising:
- receiving a trigger input signal provided through a trigger interface;
- issuing, by a voice trigger system, a trigger event based on the trigger input signal, wherein the voice trigger system, an audio subsystem, and a host processor are electrically connected to one another via a system bus in a single semiconductor chip that forms the application processor;
- processing, by the audio subsystem, audio streams that are replayed or recorded through an audio interface;
- disabling the trigger interface while an audio replay operation is performed through an output pad of the audio interface;
- receiving, by the audio sub system, an audio input signal through an input pad of the audio interface while the audio replay operation is performed simultaneously through the output pad of the audio interface;
- and
- performing, by the voice trigger system, the voice trigger operation based on the audio input signal while the audio replay operation is performed through the output pad of the audio interface.
