Fig. 1 shows a flowchart of a power consumption control method for a GPU provided by an embodiment of the present disclosure. In one possible implementation, the execution subject of the power consumption control method of the GPU (Graphics Processing Unit, graphics processor) may be a power consumption control device for the GPU, for example, the power consumption control method for the GPU may be executed by a terminal device or a server or other electronic device.

In step S14, a target operating frequency of the GPU is determined according to the current operating frequency and the current scaling factor.
In the embodiment of the disclosure, the power consumption of the GPU is controlled based on the current power consumption of the GPU.
In one possible implementation manner, the obtaining the current power consumption of the GPU includes: acquiring sampling power consumption of the GPU; and filtering the sampling power consumption to obtain the current power consumption of the GPU.
In this implementation, the sampled power consumption of the GPU may represent the power consumption resulting from sampling the power consumption of the GPU.
In the implementation manner, filtering modes such as average filtering and the like can be adopted to filter the sampling power consumption of the GPU, so that the current power consumption of the GPU is obtained.

As an example of this implementation, the obtaining the sampling power consumption of the GPU includes: collecting the power consumption of the GPU through a peripheral power consumption collecting device; and acquiring the sampling power consumption of the GPU from the power consumption acquisition device at a preset frequency.
For example, the power consumption collection device may be the INA3221 or the like, and is not limited herein. In this example, the sampled power consumption of the GPU may be obtained from a power consumption harvesting device. For example, the sampled power consumption of the GPU may be obtained from the power consumption acquisition device at a preset frequency.
In one example, the power consumption acquisition device may interact with the power consumption acquisition device through a preset communication protocol to acquire the power consumption of the GPU. For example, the preset communication protocol may be an I2C (Inter-Integrated Circuit, integrated circuit) communication protocol, etc., which is not limited herein.
In one example, the method further comprises: and initializing the power consumption acquisition device in response to the starting of the GPU.
In this example, the power consumption of the GPU is collected by the peripheral power consumption collection device, and the sampling power consumption of the GPU is obtained from the power consumption collection device at a preset frequency, so that the efficiency of GPU power consumption control can be improved.
In another possible implementation manner, the obtaining the current power consumption of the GPU includes: and acquiring the sampling power consumption of the GPU as the current power consumption of the GPU. In this implementation, the latest sampled power consumption output by the power consumption acquisition device may be directly used as the current power consumption of the GPU, without filtering.
In one possible implementation, the current power consumption of the GPU may be obtained based on a timing duration or a preset frequency, and the power consumption of the GPU may be controlled based on the current power consumption of the GPU. In this implementation, by obtaining the current power consumption of the GPU based on the timing duration or the preset frequency, more reliable and efficient power consumption control of the GPU can be achieved.
In the embodiments of the present disclosure, the target power consumption of the GPU may represent a target value of the power consumption of the GPU, i.e., the power consumption that the GPU is expected to achieve. Under the target power consumption, the GPU can achieve higher performance and is safe in chip.
The power consumption of the GPU may represent the total power consumption of the GPU, which may include the dynamic power consumption of the GPU and the static power of the GPUConsumption is reduced. For example, the total power consumption P of the GPU total ＝P dynamic +P static . Wherein P is dynamic Representing dynamic power consumption of GPU, P static Representing the static power consumption of the GPU. The static power consumption of the GPU may be a fixed value, and may be measured by an oscilloscope or may be obtained by other means.
At the process node before 40nm, the dynamic power consumption of the GPU is a large percentage of the total power consumption. With the evolution of the process, the static power consumption gradually increases in the ratio of the total power consumption to the extent comparable to the dynamic power consumption at 7nm, which further increases the difficulty of implementing DVFS (Dynamic Voltage and Frequency Scaling, dynamic voltage frequency adjustment).
In one example, dynamic power consumption P dynamic ＝α×C×v 2 X f. Wherein alpha is the turnover rate, C is the load capacitance, v is the working voltage, and f is the working frequency. Therefore, by reducing the operating frequency, the purpose of reducing power consumption can be achieved.
In the embodiment of the disclosure, the current scaling factor may be determined according to the current power consumption of the GPU, the target power consumption of the GPU, and the static power consumption of the GPU, where the current scaling factor is used to determine the target operating frequency of the GPU.
In one possible implementation manner, the determining the current scaling factor according to the current power consumption, the target power consumption and the static power consumption includes: determining a first difference between the target power consumption and the static power consumption; determining a second difference between the current power consumption and the static power consumption; a current scaling factor between the first difference and the second difference is determined.
In this implementation, the first difference may represent a difference between the target power consumption and the static power consumption, and the second difference may represent a difference between the current power consumption and the static power consumption. In this implementation, the ratio of the first difference to the second difference may be determined as the current scaling factor. For example, a= (P) set -P static )/(P current -P static ) The current scaling factor a is determined. Wherein P is set Representing target power consumption, P static Representing static power consumption, P current Representing the current power consumption.
As one example of this implementation, the product of the current operating frequency and the current scaling factor may be determined as the target operating frequency.
In this implementation, by determining a first difference between the target power consumption and the static power consumption, determining a second difference between the current power consumption and the static power consumption, and determining a current scaling factor between the first difference and the second difference, the current scaling factor can be reasonably determined. And determining the target working frequency of the GPU based on the determined current scaling factor, thereby being beneficial to improving the safety and performance of the GPU.
In another possible implementation manner, the determining the current scaling factor according to the current power consumption, the target power consumption and the static power consumption includes: determining a first difference between the target power consumption and the static power consumption; determining a second difference between the current power consumption and the static power consumption; a current scaling factor between the second difference and the first difference is determined.
In this implementation, the first difference may represent a difference between the target power consumption and the static power consumption, and the second difference may represent a difference between the current power consumption and the static power consumption. In this implementation, the ratio of the second difference to the first difference may be determined as the current scaling factor. For example, a= (P) current -P static )/(P set -P static ) The current scaling factor a is determined. Wherein P is set Representing target power consumption, P static Representing static power consumption, P current Representing the current power consumption.
As an example of this implementation, the current operating frequency may be divided by the current scaling factor to obtain the target operating frequency.
In one possible implementation manner, the determining the target operating frequency of the GPU according to the current operating frequency and the current scaling factor includes: and responding to the GPU in a power consumption control state, and determining the target working frequency of the GPU according to the current working frequency and the current proportionality coefficient.
In this implementation, the power consumption control state may represent a state in which the power consumption of the GPU needs to be reduced.
In this implementation manner, the target operating frequency of the GPU is determined according to the current operating frequency and the current scaling factor in response to the GPU being in the power consumption control state, so that the power consumption of the GPU can be reduced by reducing the operating frequency of the GPU when the GPU is in the power consumption control state, and the power consumption of the GPU can be controlled when the GPU is not in the power consumption control state, so that unnecessary power consumption control can be reduced, and the efficiency of performing power consumption control on the GPU can be improved.
As an example of this implementation, the method further comprises: judging whether the GPU is in the power consumption control state or not according to the current power consumption, preset control power consumption and preset exit power consumption, wherein the preset control power consumption is higher than the preset exit power consumption.
The preset control power consumption may represent a preset power consumption value for controlling the GPU to enter a power consumption control state, and the preset exit power consumption may represent a preset power consumption value for controlling the GPU to exit the power consumption control state.
In this example, by determining whether the GPU is in the power consumption control state according to the current power consumption, a preset control power consumption, and a preset exit power consumption, the preset control power consumption is higher than the preset exit power consumption, thereby enabling effective power consumption control of the GPU.
In one example, the determining whether the GPU is in the power consumption control state according to the current power consumption, the preset control power consumption, and the preset exit power consumption includes: and in response to the GPU being in the power consumption control state, and the continuous times that the power consumption of the GPU is smaller than the preset exit power consumption not reaching the preset times, determining that the GPU is continuously in the power consumption control state, wherein the preset times are larger than 1.
In this example, if the GPU is in the power consumption control state before the current power consumption of the GPU is acquired this time and the current power consumption of the GPU is greater than or equal to the preset exit power consumption, it may be determined that the number of consecutive times that the power consumption of the GPU is less than the preset exit power consumption is 0, and the preset number of times is not reached, so that it may be determined that the GPU continues to be in the power consumption control state.
If the GPU is in the power consumption control state before the current power consumption of the GPU is obtained this time and the current power consumption of the GPU is less than the preset exit power consumption, it can be further determined whether the continuous times of the power consumption of the GPU less than the preset exit power consumption reaches the preset times. If the power consumption of the GPU is less than the preset number of times of exiting power consumption, the GPU may be determined to be in the power consumption control state continuously.
In this example, the power consumption of the GPU can be stably controlled at the target power consumption by setting the delay of the preset times to exit the power consumption control state, so that more power consumption scenes can be compatible, and the performance loss in the power consumption control can be effectively reduced.
In one example, the determining whether the GPU is in the power consumption control state according to the current power consumption, the preset control power consumption, and the preset exit power consumption includes: and responding to the GPU in the power consumption control state, wherein the current power consumption is smaller than the preset exit power consumption, and the continuous times of which the power consumption of the GPU is smaller than the preset exit power consumption reach the preset times, and determining that the GPU exits from the power consumption control state.
If the GPU is in the power consumption control state before the current power consumption of the GPU is obtained this time and the current power consumption of the GPU is less than the preset exit power consumption, it can be further determined whether the continuous times of the power consumption of the GPU less than the preset exit power consumption reaches the preset times. If the power consumption of the GPU is smaller than the preset continuous times of the exiting power consumption and reaches the preset times, the GPU exiting power consumption control state can be determined.
In this example, the power consumption of the GPU can be stably controlled at the target power consumption by setting the delay of the preset times to exit the power consumption control state, so that more power consumption scenes can be compatible, and the performance loss in the power consumption control can be effectively reduced.
In one example, the determining whether the GPU is in the power consumption control state according to the current power consumption, the preset control power consumption, and the preset exit power consumption includes: determining that the GPU enters the power consumption control state in response to the fact that the GPU is not in the power consumption control state and the current power consumption is larger than or equal to preset control power consumption; or, in response to the GPU not being in the power consumption control state and the current power consumption being less than the preset control power consumption, determining that the GPU is not in the power consumption control state.
If the GPU is not in the power consumption control state before the current power consumption of the GPU is acquired, and the current power consumption of the GPU is greater than or equal to the preset control power consumption, the GPU can be determined to enter the power consumption control state.
If the GPU is not in the power consumption control state before the current power consumption of the GPU is acquired, and the current power consumption of the GPU is smaller than the preset control power consumption, the GPU can be determined not to enter the power consumption control state.
In another example, the determining whether the GPU is in the power consumption control state according to the current power consumption, the preset control power consumption, and the preset exit power consumption includes: determining that the GPU exits the power consumption control state in response to the GPU being in the power consumption control state and the current power consumption of the GPU being smaller than a preset exit power consumption; or, in response to the GPU being in the power consumption control state, the current power consumption is greater than or equal to the preset exit power consumption, determining that the GPU is continuously in the power consumption control state; or, in response to the GPU not being in the power consumption control state and the current power consumption being greater than or equal to a preset control power consumption, determining that the GPU enters the power consumption control state; or, in response to the GPU not being in the power consumption control state and the current power consumption being less than the preset control power consumption, determining that the GPU is not in the power consumption control state.
As another example of this implementation, the method further includes: and judging whether the GPU is in the power consumption control state according to the current power consumption and the preset control power consumption.

In another example, the determining whether the GPU is in the power consumption control state according to the current power consumption and the preset control power consumption includes: responding to the GPU in the power consumption control state, wherein the current power consumption of the GPU is larger than or equal to the preset control power consumption, and determining that the GPU is continuously in the power consumption control state; determining that the GPU exits the power consumption control state in response to the GPU being in the power consumption control state and the current power consumption of the GPU being smaller than the preset control power consumption; determining that the GPU enters the power consumption control state in response to the fact that the GPU is not in the power consumption control state and the current power consumption is larger than or equal to preset control power consumption; and determining that the GPU is not in the power consumption control state in response to the GPU is not in the power consumption control state and the current power consumption is smaller than the preset control power consumption.
In another possible implementation manner, the target operating frequency of the GPU may be determined directly according to the current operating frequency and the current scaling factor, regardless of whether the GPU is in a power consumption control state.
In one possible implementation, the method further includes: and closing external power supply of the GPU in response to the temperature of the GPU being greater than or equal to a preset maximum operating temperature.
In this implementation, the preset maximum operating temperature may be obtained by testing a temperature threshold at which the GPU is powered off.
In the implementation manner, the external power supply of the GPU is turned off in response to the fact that the temperature of the GPU is greater than or equal to the preset highest running temperature, so that the shutdown of the display card is controlled, and therefore the safety of the GPU can be improved.
