In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In some of them embodiment of the present invention, propose a kind of cooling control method, this cooling control method is applied to the electronic equipment with multi-processor structure.
In one embodiment, multi-processor structure refers to single SoC (SystemonChip) chip comprising multiple processor, the valiant dragon for smart mobile phone that such as QualCom company releases
tMprocessor, the processor comprised can be central processing unit (CentralProcessingUnit, CPU), Graphics Processing Unit (GraphicsProcessingUnit, GPU), one or more the combination wherein such as visual processing unit (VideoProcessingUnit, VPU).
As shown in Figure 1, the cooling control method in one embodiment of the present of invention, comprises the following steps:
Step 102, monitors temperature and the load factor of multiple processor.
In one embodiment, described multiple processor is single SoC (SystemonChip, SOC (system on a chip)) multiple processors on chip, described processor can be central processing unit (CentralProcessingUnit, CPU), Graphics Processing Unit (GraphicsProcessingUnit, GPU), visual processing unit (VideoProcessingUnit, VPU) etc.Such as, existing typically can have 4,6 or 8 cores (sometimes also claim core cpu or be directly called CPU) for the processor chips of intelligent mobile terminal.Understandable, described processor is not limited to afore-mentioned, and in other embodiments, described processor can refer to that other have the assembly of computing power.
The load factor of processor, as the term suggests be exactly the statistics of the behaviour in service to a time period inner treater, can find out in the occupied situation of some time period inner treaters by this index, if occupied time is very high, so just need to consider whether processor has been in overload running, long-term overload running can make electronic equipment keep a kind of state of high temperature for a long time, this is a kind of infringement concerning electronic equipment itself, therefore must the load factor of processor be controlled under certain ratio, working temperature by processor keeps within the specific limits, to ensure the normal operation of electronic equipment.
In some of them embodiment of the present invention, plug-in unit in the operating system of electronic equipment (such as the Android of Google of the U.S.) can be adopted to monitor the load factor of each processor in real time.Described plug-in unit is can dynamic load/unloading, such as, drive.
In addition, in some of them embodiment of the present invention, the number of the processor in multi-processor structure is at least 2, in order to describe the needs of method of the present invention, introduce the concept of " first processor " and " the second processor ", first processor is used for characterizing in the present invention the processor that the load factor detected is continued above the predetermined threshold value schedule time, and the second processor is used for characterizing the minimum processor of the temperature that detects in the present invention.In practice, " first processor " and " the second processor " are the identical logical device of 26S Proteasome Structure and Function in above-mentioned multi-processor structure, " first " and " second " are only relative concepts, " first " and " second " can not be interpreted as limitation of the present invention.
In some of them embodiment of the present invention, temperature sensor can be adopted to gather the temperature of multiple processor in real time.Here temperature sensor can be one, also can be multiple, and such as, each processor is equipped with a temperature sensor, or detects the temperature of multiple processor respectively by a temperature sensor.The hardware driving of the load factor for measurement processor of above-mentioned some of them embodiment, because this hardware driving contains hardware information, the information of temperature sensor can be transmitted by this hardware driving, so just can by the temperature of each processor that detects in real time and load factor to be for further processing.
Further, in some of them embodiment of the present invention, from high to low descending sort is carried out to each processor according to load factor, obtain and store the mark of each processor and each processor concordance list in not temperature in the same time and load factor, the higher first processor of load factor and minimum the second processor of temperature can be found according to this concordance list.In the present embodiment, processor flag can be but be not limited to the model of number designation and processor.
Step 104, judges whether to there is the first processor that load factor is continued above the predetermined threshold value schedule time, if so, then performs step 106: the load of first processor is moved the second processor that temperature is minimum, otherwise, then continue to perform step 102.
In some of them embodiment of the present invention, predetermined threshold value generally takes the rule of 0.7 under normal circumstances, namely the load factor of each processor is no more than 70%, and when multi-processor structure comprises 4 processors, the overall load of this multi-processor structure does not exceed 4*0.7=2.8.In the observation process of reality, the scope of Preset Time, before the mobile terminal of mobile phone etc. can be selected in 2 seconds to 30 seconds, notebook computer etc. can be selected between 1 minute to 10 minutes, because the multi-task is concurrent within the extremely short time sometimes, understand the load factor of fast lifting processor momently.
