Detailed description of the invention
The embodiment of the present invention provides a kind of sensor control method, is used for controlling sensor and interrupts, to reduce
The power consumption of ADSP.The embodiment of the present invention also provides for corresponding device.
In order to make those skilled in the art be more fully understood that the present invention program, implement below in conjunction with the present invention
Accompanying drawing in example, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that institute
The embodiment described is only the embodiment of a present invention part rather than whole embodiments.Based on this
Embodiment in bright, the institute that those of ordinary skill in the art are obtained under not making creative work premise
There are other embodiments, all should belong to the scope of protection of the invention.
Below by specific embodiment, it is described in detail respectively.
Embodiment one,
Refer to Fig. 1, the embodiment of the present invention provides a kind of sensor control method.
Embodiment of the present invention method is used for various terminals, such as mobile phone, panel computer etc..Described terminal includes
Sensor and processor.Described processor includes: that be connected with described sensor, for processing in sensor
Disconnected ADSP, and the AP being connected with described ADSP.Residing sensor can include pedometer.
Wherein, AP is the processor of ARM framework, is used for running Linux+Android (Android) system；
During general cell phone standby, AP enters resting state, and at this moment in Android, the code of application program also can stop
Perform.
ADSP is the one of DSP (Digital Signal Processor, digital signal processor), is used for locating
Reason audio digital signals.DSP by extensive or VLSI chip form for completing certain
Planting the processor of signal processing tasks, it is for adapting to the needs of High speed real-time signal processing task and gradually to send out
Exhibition is got up.
Pedometer is by data such as statistics step number, distance, speed, times, and measuring and calculating calorie or heat disappear
Consumption, in order to control quantity of motion, prevents quantity of motion not enough, or a kind of instrument of excessive movement.The work of pedometer
It is exactly shaking sensor as core.
Sensor is detecting signal, such as, the when that pedometer detecting step of user, will produce interruption,
Generate interrupt signal；ADSP is the processor of management of sensor, the terminal produced for response sensor, right
Interrupt signal processes.
When terminal in a dormant state time, ADSP also can dormancy, but, the various sensors such as pedometer are usual
Will not dormancy, can be badly in need of detecting signal, and produce interruption, once sensor produces and interrupts, and ADSP will be by
Sensor interrupts waking up up, and processes interrupt signal.
When sensor includes pedometer, ADSP can respond the interruption of pedometer always, say, that ADSP
The state waken up up by interruption can be constantly in.This can be greatly increased the power consumption of ADSP.
In order to reduce the power consumption of ADSP, embodiments provide sensor control method as shown in Figure 1,
The method may include that
101, the state of described AP is obtained.
Executive agent herein can be terminal, and is as a example by the mobile phone using android system by terminal.
In this step, the ADSP in terminal can obtain the state of AP in real time.The state of AP can include dormancy shape
State and wake-up states two kinds.When AP in a dormant state time it can be understood as system in a dormant state；When
It can be understood as system is in wake-up states when AP is in wake-up states.Described system refers to the operation of terminal
System, such as, can be Android (Android) system.
In some embodiments, the state of AP is by represented by the mark of a dormancy awakening, and terminal can obtain AP
The mark of dormancy awakening, described mark indicates described AP in a dormant state or to be in wake-up states.
102, when described AP in a dormant state time, closure sensor interrupt.
In this step, when confirming that AP is in a dormant state, closure sensor interrupts, makes sensor no longer produce
Raw interruption the most not regeneration interrupt signal.But it should be recognized that although closure sensor interrupts, but
Not affecting normal operation of sensor, as a example by pedometer, pedometer internal meter step is also being carried out, and continues to
Monitoring step of user number, does not the most produce interruption, does not wake up ADSP up.
In some embodiments, when AP in a dormant state when, ADSP can be by the shape of interface document
Formula closes pedometer interruption, makes pedometer no longer produce interrupt signal, then ADSP also would not be waken up,
So may dispense with the power consumption of ADSP.
103, when described AP is in wake-up states, enable sensor and interrupt.
In this step, when confirming that AP is in wake-up states, enable sensor and interrupt, make sensor to produce
Raw interruption can generate interrupt signal in other words, responds it is thus possible to wake up ADSP up and processes interruption.
In some embodiments, when AP is in wake-up states when, ADSP can be by the shape of interface document
Formula enables pedometer and interrupts so that pedometer interrupt signal can be by ADSP process, then ADSP will be clear
The paces number that now pedometer reports is known on ground, this paces number is reported AP simultaneously, can be used for for pedometer
Relevant application uses.
If it should be noted that the when of system wake-up, user does not walks, and pedometer is not led
Moving if reporting paces, the paces that user passed by system sleep when just now will be lost, and causes meter
The mistake of step.It is preferred, therefore, that when system is waken up when, in other words, wake up up when described AP is in
During state, not only enabling pedometer and interrupt, meanwhile, pedometer to be controlled is actively by current pedometer paces
Number reports to ADSP, and then ADSP reports AP.
So, under ADSP framework, by dynamically adjusting the interruption of pedometer, both can realize accurately counting step,
The power consumption of ADSP can be reduced again, reach the purpose of power saving.
It is appreciated that embodiment of the present invention such scheme such as can be embodied as in terminals such as mobile phones.
Therefore, in some feasible embodiments of the present invention, can dynamically adjust sensor and interrupt,
Wherein, when AP in a dormant state time, closure sensor interrupt so that ADSP is without in response sensor
Disconnected, it is no longer on being interrupted the state waken up up, such that it is able to reduce the power consumption of ADSP, reaches to make saving power for terminal
Purpose, and do not affect normal operation of sensor.
In order to preferably implement the such scheme of the embodiment of the present invention, it is also provided below for coordinating enforcement above-mentioned
The relevant apparatus of scheme.
