Problems solved by technology

When triggering devices such as touch screens and buttons generate trigger events due to user manipulation, the system can adjust the processor frequency to the highest frequency as required. However, for sensors such as acceleration sensors, proximity sensors, and gyroscope sensors, due to fixed sampling, Interruption and other non-user manipulation operations will also generate trigger events. The continuous sampling or interruption of the trigger device will cause frequent trigger events in the system. A large number of frequency adjustment instructions will maintain the processor at the highest frequency, which will affect the performance of electronic equipment. consumes a lot of burden

Abstract

The embodiment of the invention provides a processor frequency control method and electronic equipment, and relates to the technical field of electronics. Frequency adjusting instructions of a processor can be selectively executed according to the types of triggering events. The processor frequency control method comprises the following steps of according to one frequency adjusting instruction received by the processor, judging the type of the corresponding triggering event; according to the judging result, when the triggering event is a first-type triggering event, executing the frequency adjusting instruction. The processor frequency control method and the electronic equipment are used for controlling the frequency of the processor, and decreasing the power consumption of the electronic equipment.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a processor frequency control method and electronic equipment. Background technique [0002] At present, electronic devices such as smart phones and tablet computers can adjust the frequency of the processor according to the current task load. Among various processor frequency adjustment methods, the Ondemand algorithm has high versatility. [0003] The Ondemand algorithm means that when the task load of the electronic device is low, the processor runs at a relatively low frequency, and automatically increases the frequency when the system load increases. Running in this mode will not reduce the performance of the electronic device due to the frequency reduction of the processor, and at the same time save power and lower the temperature, taking into account the performance and power consumption of the electronic device. At the same time, in order to increase the real-time p...
