All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The invention provides a power consumption adjusting method, and fig. 1 is a flow diagram of the power consumption adjusting method provided by the invention. Referring to fig. 1, a power consumption adjustment method provided by the present invention may include:
The execution subject of the power consumption adjustment method provided by the invention can be an electronic device, a component in the electronic device, an integrated circuit, or a chip. The electronic device may be a mobile electronic device or a non-mobile electronic device. For example, the mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palmtop computer, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile electronic device may be a server, a Network Attached Storage (NAS), a Personal Computer (PC), and the like, and the present invention is not limited in particular.
The following describes the technical solution of the present invention in detail by taking a computer as an example to execute the power consumption adjustment method provided by the present invention.
In step 110, model information of the processor, a heat dissipation design power consumption level of the processor, and frequency range information of the processor are obtained, and an energy efficiency ratio curve during the operation of the processor is determined.
The model information of the processor, the heat dissipation design power consumption level of the processor and the frequency range information of the processor are basic information of the processor. Based on the model information of the processor, various parameters of the processor can be determined, including the main frequency, the frequency multiplication, the external frequency, the bus frequency, the secondary cache, the working voltage, the interface, the architecture type, the manufacturing process and the like of the processor. Based on the model information of the processor, performance indicators reflecting various performances of the processor can be determined.
The processor's TDP (Thermal Design Power, thermal Design Power level) is the processor's current Thermal effect and other heat generated by the processor during operation. The TDP power consumption is usually used as an important reference index for heat dissipation/consumption reduction design such as computer or server motherboard design, heat dissipation system design, large-scale server heat dissipation design, and the larger the TDP is, the larger the heat generated by the processor during operation is, and for the heat dissipation system, the TDP needs to be used as the lowest index/basic index for heat dissipation capability design. That is, at least the amount of heat represented by the TDP value is dissipated. For example, a notebook computer processor heat dissipation system may be designed as a 20W TDP, which means that it can dissipate 20W of heat (either by active heat dissipation means such as using a fan, or passive heat dissipation means such as a heat pipe) to ensure that the processor temperature itself does not exceed the maximum junction temperature of the wafer. The TDP of a processor can reflect the maximum load that the processor can withstand while running.
The frequency range of the processor is the frequency range of the core and the non-core when the processor works, and the operation speed of the calculation is determined based on the frequency range of the processor, the clock frequency and the working frequency when the processor works.
Based on the model information of the processor, the heat dissipation design power consumption level of the processor and the frequency range information of the processor, the ideal working states of the processor under different loads can be determined when the processor runs, so that the ideal working states of the processor from low load to high load can be determined, and the energy efficiency ratio curve of the processor under the optimal running state can be further determined.
It can be understood that the energy efficiency ratio curve of the processor reflects the optimal operation curve of various parameters, power consumption, performance and the like of the processor along with the change of the load. And determining the corresponding optimal running state of the processor under various load conditions based on the load change of the processor.
In step 120, the real-time load of the processor and the real-time power consumption of the processor during the real-time operation of the processor are obtained. Based on the energy efficiency ratio curve of the processor determined in step 110, a target power consumption corresponding to the real-time load of the processor in the energy efficiency ratio curve is determined, and the real-time power consumption is determined to exceed a preset fluctuation range of the target power consumption.
The real-time power consumption and the real-time load of the processor can be acquired periodically when the processor is running. The operating state of the current processor is determined in real time. After the real-time load and the real-time power consumption of the processor are obtained, the target power consumption corresponding to the real-time load of the current processor is determined from the energy efficiency ratio curve. And comparing the real-time power consumption with a preset fluctuation range of the target power consumption.
It can be understood that the target power consumption of the real-time load in the energy efficiency ratio curve is the optimal power consumption corresponding to the real-time load of the current processor. Namely, the power consumption of the optimal working state under the condition that the current processor is under the real-time load is the target power consumption.
After the target power consumption corresponding to the optimal working state of the processor is determined, a preset fluctuation range of the target power consumption can be determined. That is, the real-time power consumption of the processor under the real-time load condition may indicate that the operating state of the processor is better if the real-time power consumption is within the preset fluctuation range of the target power consumption.
The preset fluctuation range of the target power consumption can be manually set according to historical operating data of the processor. If the real-time power consumption of the processor does not exceed the preset fluctuation range of the target power consumption, the processor can be determined to be in a better running state and the energy consumption is relatively moderate.
It can be understood that, if the real-time power consumption of the processor exceeds the preset fluctuation range of the target power consumption, it indicates that the energy consumption of the processor is high under the current real-time load condition, and the operating state of the processor needs to be adjusted, so as to optimize the operating mode of the processor and reduce the energy consumption of the processor.
In step 130, after determining that the real-time power consumption of the processor exceeds the preset fluctuation range of the target power consumption in step 120, the operating state of the processor is adjusted based on the preset fluctuation range of the target power consumption of the processor determined in the energy efficiency ratio curve, so as to reduce the power consumption of the processor.
It can be understood that the target power consumption of the real-time load in the energy efficiency ratio curve is the optimal power consumption corresponding to the real-time load of the current processor. Namely, the power consumption of the optimal working state of the current processor under the condition of real-time load is the target power consumption.
And adjusting the working state of the processor based on the target power consumption corresponding to the optimal working state of the processing area under the condition of real-time load, so that the power consumption of the processor is adjusted to be within a preset fluctuation range of the target power consumption, and the optimized adjustment of the operation of the processor is realized.
It can be understood that the adjustment of the operating state of the processor to adjust the power consumption of the processor to be within the preset fluctuation range of the target power consumption does not directly reduce the power consumption of the processor. But reduces the power consumption of the processor to a reasonable range, thereby realizing the accurate regulation and control of the power consumption of the processor.

The method comprises the steps of determining target power consumption corresponding to a real-time load in an energy efficiency ratio curve based on the real-time load and the real-time power consumption when the processor runs, and adjusting the power consumption of the processor to be within a preset fluctuation range of the target power consumption based on a preset fluctuation range of the target power consumption, so that the power consumption of the processor is reduced, and the dynamic adjustment of the power consumption of the processor is realized. The power consumption of the processor is reduced to a reasonable range, the power consumption of the processor is not directly reduced to the minimum, and the accurate regulation and control of the power consumption of the processor are realized.
In one embodiment, adjusting the operating state of the processor based on the preset fluctuation range of the target power consumption includes: determining a target core frequency range of the processor corresponding to a preset fluctuation range of the target power consumption and a target non-core frequency range of the processor corresponding to the preset fluctuation range of the target power consumption based on the preset fluctuation range of the target power consumption; adjusting an operating state of the processor based on the target core frequency range and the target non-core frequency range.

The core frequency and the non-core frequency of the processor can be adjusted through the target core frequency range and the target non-core frequency range of the processor corresponding to the preset fluctuation range of the target power consumption, and the running state of the processor can be adjusted.
The processor in the related method is generally a multi-core processor, which includes a core and a plurality of non-cores. Based on the determination and adjustment of the core frequency and the uncore frequency of the processor, the adjustment of the frequency of the processor can be realized, thereby finally realizing the adjustment of the running state of the processor.
According to the power consumption adjusting method provided by the embodiment of the invention, the target core frequency range and the target non-core frequency range of the processor corresponding to the preset fluctuation range of the target power consumption are determined through the preset fluctuation range of the target power consumption, and the core frequency and the non-core frequency of the processor are adjusted, so that the adjustment of the running state of the processor is realized.
In one embodiment, adjusting the operating state of the processor based on the target core frequency range and the target uncore frequency range includes: setting a core frequency of the processor to a frequency in the target core frequency range and setting a non-core frequency of the processor to a frequency in the target non-core frequency range.
And determining a target core frequency range and a target non-core frequency range of the processor corresponding to the preset fluctuation range of the target power consumption based on the preset fluctuation range of the target power consumption. The core frequency of the processor is set to a frequency in the target core frequency range and the uncore frequency of the processor is set to a frequency in the target uncore frequency range.
Based on the determination and adjustment of the core frequency and the uncore frequency of the processor, the adjustment of the frequency of the processor can be realized, thereby finally realizing the adjustment of the running state of the processor.
According to the power consumption adjusting method provided by the embodiment of the invention, the core frequency and the non-core frequency of the processor are adjusted by determining the target core frequency range and the target non-core frequency range of the processor corresponding to the preset fluctuation range of the target power consumption, setting the core frequency of the processor as the frequency in the target core frequency range and setting the non-core frequency of the processor as the frequency in the target non-core frequency range, so that the adjustment of the core frequency and the non-core frequency of the processor is realized, and the adjustment of the running state of the processor is realized.
In one embodiment, adjusting the operating state of the processor based on the preset fluctuation range of the target power consumption includes: determining a target performance parameter of the processor corresponding to the real-time load based on the real-time load; and adjusting the performance parameters of the processor and the real-time power consumption of the processor based on the target performance parameters and the preset fluctuation range of the target power consumption so as to enable the adjusted power consumption of the processor to be within the preset fluctuation range of the target power consumption.
After the real-time load of the processor is determined, the target performance parameters of the processor corresponding to the real-time load are determined. The target performance parameter of the processor is the ideal performance parameter of the processor under real-time load. After the target performance parameter of the processor is determined, the performance parameter of the processor and the real-time power consumption of the processor are adjusted based on the target performance parameter of the processor and the preset fluctuation range of the target power consumption, so that the adjusted power consumption of the processor is within the preset fluctuation range of the target power consumption.
It can be understood that, based on the adjustment of the performance parameters of the processor and the real-time power consumption of the processor, the adjustment of the running state of the processor is realized, so as to finally ensure that the power consumption of the processor is within the preset fluctuation range of the target power consumption.
According to the power consumption adjusting method provided by the embodiment of the invention, after the real-time load of the processor is determined, the target performance parameter of the processor corresponding to the real-time load is determined. After the target performance parameter of the processor is determined, the performance parameter of the processor and the real-time power consumption of the processor are adjusted based on the target performance parameter of the processor and the preset fluctuation range of the target power consumption, so that the adjusted power consumption of the processor is in the preset fluctuation range of the target power consumption.
In one embodiment, the preset fluctuation range of the target power consumption is determined based on power consumption corresponding to a load with the same size as the real-time load in historical operation data of the processor.
After the target power consumption of the processor is determined, a preset fluctuation range of the target power consumption of the processor needs to be determined. The preset fluctuation range of the target power consumption can be determined according to historical operating data of the processor. Based on the power consumption corresponding to the load with the same real-time load size in the historical operating data, a fluctuation range of the load can be determined, and therefore the preset fluctuation range of the target power consumption is determined.
If the real-time power consumption of the processor does not exceed the preset fluctuation range of the target power consumption, the processor can be determined to be in a better running state and the energy consumption is relatively moderate.
It can be understood that, if the real-time power consumption of the processor exceeds the preset fluctuation range of the target power consumption, it indicates that the energy consumption of the processor is high under the current real-time load condition, and the operating state of the processor needs to be adjusted, so as to optimize the operating mode of the processor and reduce the energy consumption of the processor.
The power consumption adjusting method provided by the embodiment of the invention is determined. Based on the power consumption corresponding to the load with the same real-time load size in the historical operating data, a fluctuation range of the load can be determined, and therefore the preset fluctuation range of the target power consumption is determined.

After the real-time load of the processor is obtained, if the real-time load of the processor is determined to be larger than a preset maximum power consumption threshold value, the real-time power consumption of the processor is directly reduced and adjusted.
The preset maximum power consumption threshold of the processor is the upper power consumption limit of the processor during operation, and in the process of the processor operation, under the condition that the maximum power consumption upper limit is reached, the power consumption of the processor needs to be immediately reduced, so that the condition that equipment is damaged due to long-term full-load operation is avoided. The maximum power consumption threshold of the processor can be set according to the parameter information of the processor.
According to the power consumption adjusting method provided by the embodiment of the invention, under the condition that the real-time power consumption of the processor is determined to exceed the maximum power consumption threshold of the upper power consumption limit, the power consumption of the processor is immediately reduced and adjusted, so that the safe operation of the processor is ensured.

Based on the model information of the processor, performance indicators reflecting various performances of the processor can be determined.
The TDP of the processor is the processor current thermal effect and other heat generated by the processor when operating. The TDP power consumption is usually used as an important reference index for heat dissipation/consumption reduction design such as computer or server motherboard design, heat dissipation system design, and large-scale server heat dissipation design, and the larger the TDP is, the larger the heat generated by the processor during operation is, and for the heat dissipation system, the TDP is required to be used as the lowest index/basic index for heat dissipation capability design. That is, at least the amount of heat represented by the TDP value is dissipated. For example, a notebook processor heat dissipation system may be designed as a 20W TDP, which means that it can dissipate 20W of heat (either by active heat dissipation means such as using a fan, or passive heat dissipation means such as a heat pipe) to ensure that the processor temperature does not exceed the maximum junction temperature of the die. The TDP of a processor can reflect the maximum load that the processor can withstand while running.

It can be understood that the energy efficiency ratio curve of the processor reflects the optimal operation curve of various parameters, power consumption, performance and the like of the processor along with the change of the load. And determining the corresponding optimal running state of the processor under various load conditions based on the load change of the processor.
The determining module 520 is configured to obtain a real-time load of the processor and a real-time power consumption of the processor, and determine that the real-time power consumption exceeds a preset fluctuation range of the target power consumption based on a target power consumption corresponding to the real-time load in the energy efficiency ratio curve.
The real-time power consumption and the real-time load of the processor can be acquired periodically when the processor is running. The operating state of the current processor is determined in real time. After the real-time load and the real-time power consumption of the processor are obtained, the target power consumption corresponding to the real-time load of the current processor is determined from the energy efficiency ratio curve. And comparing the real-time power consumption with a preset fluctuation range of the target power consumption.
It can be understood that the target power consumption of the real-time load in the energy efficiency ratio curve is the optimal power consumption corresponding to the real-time load of the current processor. Namely, the power consumption of the optimal working state of the current processor under the condition of real-time load is the target power consumption.
After the target power consumption corresponding to the optimal working state of the processor is determined, a preset fluctuation range of the target power consumption can be determined. That is, the real-time power consumption of the processor under the real-time load condition may indicate that the operating state of the processor is better if the real-time power consumption is within the preset fluctuation range of the target power consumption.
The preset fluctuation range of the target power consumption can be set manually according to the historical operating data of the processor. If the real-time power consumption of the processor does not exceed the preset fluctuation range of the target power consumption, the processor can be determined to be in a better running state and the energy consumption is relatively moderate.
It can be understood that, if the real-time power consumption of the processor exceeds the preset fluctuation range of the target power consumption, it indicates that the energy consumption of the processor is high under the current real-time load condition, and the operating state of the processor needs to be adjusted, so as to optimize the operating mode of the processor and reduce the energy consumption of the processor.
