Publication number: 20180224923Abstract: Systems and techniques for lower power key phrase detection are disclosed herein. An audio sample may be captured in a power management integrated circuit (PMIC). Here, the PMIC is physically different than a sensor circuit of an integrated system and the PMIC has a lower power leakage than the sensor circuit. The integrated system may be awoken upon a trigger. The audio sample may then be transferred to the integrated system to perform key phrase detection (KPD). The integrated system may be put to sleep in response to completion of the KPD.Type: ApplicationFiled: February 8, 2017Publication date: August 9, 2018Inventors: Vinu K.

Patent number: 8612782Abstract: A power control manager includes a processor to compute available power from a power source and a comparator to compare the available power to an amount of power to concurrently operate a plurality of sub-systems of an electronic device at full or a predetermined power. The processor generates one or more control signals in response to a decision signal output from the comparator. The control signals may indicate that a maximum power setting is to be set for a first sub-system and a reduced non-zero power setting is to be set for a second sub-system of the plurality of sub-systems. The sub-systems may be different sub-systems of a smartphone or another electronic device.Type: GrantFiled: March 31, 2011Date of Patent: December 17, 2013Assignee: Intel CorporationInventors: Reed D.
