Embodiment 1

[0018] Please refer to figure 1 , an embodiment of the present invention provides a sensor control method.

[0019] The method in the embodiment of the present invention is applied to various terminals, such as mobile phones, tablet computers, and the like. The terminal includes a sensor and a processor. The processor includes: an ADSP connected to the sensor for processing sensor interrupts, and an AP connected to the ADSP. The location sensor may include a pedometer.

[0020] Among them, the AP is a processor of ARM architecture, which is used to run the Linux+Android (Android) system; when the mobile phone is generally in standby, the AP enters a dormant state, and at this time, the code of the application program in the Android will also stop executing.

[0021] ADSP is a kind of DSP (Digital Signal Processor, digital signal processor), which is used to process audio digital signals. DSP is a processor composed of large-scale or ultra-large-scale integrated circuit chi...

Embodiment 2

[0043] Please refer to figure 2, the embodiment of the present invention provides a sensor control device 200, the device 200 is used for a terminal, the terminal includes a sensor, an audio digital signal processor ADSP connected to the sensor and used for processing sensor interruption, and connected to the sensor The application processor AP connected to the ADSP;

[0044] The device 200 may include:

[0045] An acquisition module 201, configured to acquire the state of the AP;

[0046] The control module 202 is configured to disable sensor interrupts when the AP is in a dormant state; enable sensor interrupts when the AP is in a wake-up state.

[0047] In some embodiments, the sensor includes a pedometer.

[0048] In some embodiments, the control module 202 is further configured to: when the AP is in the wake-up state, control the pedometer to actively report the current number of steps of the pedometer to the ADSP.

[0049] In some embodiments, the obtaining module 2...

Embodiment 3

[0055] An embodiment of the present invention also provides a memory for storing one or more programs, and when the one or more programs are executed by a terminal including one or more processors, the terminal performs the sensor control as described above method.

Abstract

The invention discloses a sensor control method. The method is applied to a terminal. The terminal comprises a sensor, an audio digital signal processor ADSP which is connected with the sensor and is used for processing sensor interruption, and an application processor AP connected with the ADSP. The method comprises following steps of obtaining the state of the AP; shutting sensor interruption when the AP is in a sleep state; and enabling the sensor interruption when the AP is in a waking state. The invention also provides a corresponding device. According to the technical scheme, the sensor interruption can be controlled dynamically, and the power consumption of the ADSP is reduced.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a sensor control method and device. Background technique [0002] Current mobile phones generally adopt a Qualcomm ADSP (Audio Digital Digital Processor, audio digital signal processor) architecture. The Qualcomm ADSP architecture means that the sensor is mounted on the ADSP, and the ADSP centrally manages all sensors to save power consumption. Under this architecture, all sensors such as pedometers interact with ADSP, and then ADSP interacts with AP (Application Processor, application processor). [0003] Take the pedometer as an example, when the pedometer detects the steps of the user, an interrupt will be generated, and the interrupt will be reported to ADSP, and ADSP will respond and process the interrupt. Among them, when the AP is in a dormant state, that is, when the mobile phone system is dormant, the ADSP will always respond to the interruption of the pedome...
