Abstract

An electronic device includes an appended module coupled to a core having a standby state comprising a first power supply circuit, a first clock and a circuit that recognizes multiple vocal commands timed by the first clock. The appended module includes a second power supply circuit independent of the first power supply circuit, a second clock independent of the first clock and having a frequency lower than that of the first clock, digital unit timed by the second clock including a sound capture circuit that delivers a processed sound signal, and a processing unit configured in order, in the presence of a parameter of the processed sound signal greater than a threshold, to analyze the content of the processed sound signal and to deliver, when the content of the sound signal comprises a reference pattern, an activating signal to the core that can take it out of its standby state.

Description

[0001] This application claims priority from French Application No. 1462541, filed on December 16, 2014, which is hereby incorporated by reference. technical field [0002] Embodiments of the present invention relate to electronic devices that include a wake-up module distinct from the core domain. Background technique [0003] Electronic devices, in particular mobile cellular phones, smart watches and smart glasses, increasingly include modules that enable voice recognition functions to be performed. This function makes it possible, in particular, to control the electronic device with sound. [0004] In order for the device to detect voiced commands at any time, it is desirable to monitor and detect signals in the device's environment and in particular its acoustic environment. [0005] Electronic devices operating on battery power, such as mobile cellular telephones, face problems related to energy consumption optimization during continuous monitoring of the sound environ...
