Sensor data reporting method, processor and mobile terminal

Abstract

Embodiments of the invention disclose a sensor data reporting method, a processor and a mobile terminal. The method comprises the steps of keeping a processor in a power-on mode when the processor used for managing a sensor in the mobile terminal is in a sleep state; enabling the sensor and obtaining sensor data when the processor is awakened and a sensor enabling instruction is received; and reporting the sensor data to a main processor of the mobile terminal. According to the technical scheme provided by the embodiments of the method, the processor and the mobile terminal, the power failure processing is not carried out and the processor is kept in the power-on mode when the processor is in the sleep state, so that the problem of time delay caused by the power-on operation of the processor when the processor is awakened can be solved; and one or more sensors are enabled only when the instruction of enabling the one or more sensors is received, so that the problem of time delay caused by the fact that all the sensors need to be reset after the processor is awakened in the prior art is solved, and the sensor data reporting speed is increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile terminals, in particular to a sensor data reporting method, a processor and a mobile terminal. Background technique [0002] With the development of mobile terminal technology, various applications are applied to mobile terminals, and some applications require sensors to obtain some data. Therefore, more and more sensors are integrated on mobile terminals, for example, proximity sensors , ambient light sensor, etc. Exemplarily, the proximity sensor may be used to acquire proximity sensor data indicating whether the user approaches the mobile terminal, and the ambient light sensor may be used to acquire ambient light sensor data indicating the brightness of the ambient light in which the mobile terminal is located. [0003] At present, an advanced digital signal processor (advanced digital signal processor, ADSP) is set on the mobile terminal, and this processor will centr...

Problems solved by technology

That is to say, in the prior art, when the processor is woken up, it is necessary to power on the processor, and then delay for a period of time (such as 50ms), and after waiting for the power supply to stabilize, reset all the sensors again, even if the user Just enable the ambient light sensor, then all the sensors will be reset again, and then enable the ambient light sensor, and this process will definitely cause additional time-consuming and prolong the reporting time of the ambient light sensor data
