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.

An 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 includes an audio interface and processes audio streams through the audio interface. The voice trigger system is disposed in an always-powered domain where power is supplied in both of an active mode and a standby mode. The host processor and the audio subsystem are disposed in a power-save domain where power is blocked in the standby mode. The host processor launches into the active mode when the voice trigger system issues the trigger event.

To prevent process defects and wafer damage caused by improperly positioned wafers, a system and method for detecting a position of a wafer determines whether the wafer is properly positioned before executing a process. The system includes a chuck plate preferably having a supporting part configured to support a lower face of the wafer and a guide part located on a perimeter of the supporting part. A sensing unit senses a positional state of the wafer on an upper portion of the supporting part. A controller receives a signal corresponding to the positional state of the wafer from the sensing unit, and determines whether the wafer is properly positioned. The controller then sends an output control signal to an outputting unit to notify an operator of the wafer position. In this manner, process defects are avoided and a fabricating yield and operating rate of a fabrication unit increases.
