Description

Technical Field

[0001] This application relates to the field of graphics processor technology, and in particular to a method for dynamically adjusting parameters of a graphics processor, a graphics processor, and a system. Background Technology

[0002] The performance requirements of a Graphics Processing Unit (GPU) may vary depending on the task being processed or the mode it operates in. Failure to adjust GPU chip parameters in a timely manner can easily affect GPU performance or result in wasted power. For example, when the GPU needs to operate at peak performance, if the operating power cannot be adjusted to the appropriate level in time, the GPU will not be able to achieve peak performance; conversely, when the GPU is operating at low performance, failure to adjust the operating power to a lower level in time will result in wasted power.

[0003] How to dynamically adjust the parameters of a graphics processor has become an urgent problem to be solved.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0005] The inventors of this application have discovered that a Dynamic Voltage and Frequency Scaling (DVFS) scheme can be used to configure corresponding voltages and frequencies at different performance points of a GPU chip to achieve better energy efficiency. For example, some solutions integrate a DVFS hardware module on a System-on-Chip (SOC) to detect whether the current performance exceeds the performance corresponding to the current voltage and frequency, determine a suitable voltage and frequency in hardware, and then adjust the voltage and frequency of the device through a Power Management Integrated Circuit (PMIC). Other solutions integrate a DVFS hardware module within the SOC, and also integrate a Clock Management Unit (CMU) and a Power Management Unit (PMU), triggering the DVFS module in hardware to adjust the CMU and PMU.

[0006] The aforementioned adjustments to the voltage and frequency of the GPU chip are achieved by integrating a hardware DVFS module into the GPU chip. For GPU chips that do not integrate a hardware DVFS module, voltage and frequency adjustments cannot be made directly in hardware. Furthermore, integrating a hardware DVFS module into the GPU chip is complex and costly, inconvenient for adjustment, and lacks flexibility.

[0007] To address at least one or similar technical problems mentioned above, embodiments of this application provide a method, graphics processor, and system for dynamically adjusting parameters of a graphics processor, enabling dynamic adjustment of GPU parameters even when a hardware DVFS module is not integrated into the GPU chip.

[0008] This application provides a method for dynamically adjusting the parameters of a graphics processor. The method includes: determining first performance data of the graphics processor when processing a current task; sending the first performance data to an external processing unit other than the graphics processor; receiving control information determined based on the first performance data from the external processing unit; and adjusting the parameters of the graphics processor based on the control information.

[0011] This application embodiment also provides a processor for dynamically adjusting the parameters of a graphics processor, the processor comprising: a receiving unit that receives first performance data of the graphics processor when processing a current task; a processing unit that determines control information based on the first performance data; and a sending unit that sends the control information to the graphics processor, causing the graphics processor to adjust the parameters of the graphics processor according to the control information.

[0012] This application embodiment also provides a system for dynamically adjusting parameters. The system includes a graphics processor and an external processing unit. A first unit of the graphics processor determines first performance data of the graphics processor when processing a current task and sends the first performance data to the external processing unit. The external processing unit determines control information based on the first performance data and sends the control information to a second unit of the graphics processor. The second unit of the graphics processor adjusts the parameters of the graphics processor based on the control information.

[0013] This application also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the above-described method.

[0015] This application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-described method.

[0016] The beneficial effect of the embodiments of this application is that: the graphics processor obtains control information for adjusting the parameters of the graphics processor from an external processing unit, and adjusts the corresponding parameters according to the control information. Thus, even without integrating a hardware DVFS module in the graphics processor chip, the parameters of the graphics processor can be dynamically adjusted.

[0038] First aspect of the embodiments

[0039] An embodiment of the first aspect of this application provides a method for dynamically adjusting parameters of a graphics processor, the method being applied to a system for adjusting parameters, the system including a graphics processor (GPU) and an external processing unit. Figure 1 This is a schematic diagram of a method for adjusting parameters of a graphics processor according to an embodiment of the first aspect of this application. Figure 1 As shown, the method may include:

[0040] Operation 101: The first unit of the graphics processor determines the first performance data of the graphics processor when processing the current task, and sends the first performance data to an external processing unit outside the graphics processor;

[0041] Operation 102: The external processing unit determines control information based on the first performance data and sends the control information to the second unit of the graphics processor; and

[0042] Operation 103: The second unit of the graphics processor adjusts the parameters of the graphics processor according to the control information.

[0043] The graphics processor can include any processor capable of processing graphics tasks, and it can also have general computing capabilities, audio and video processing capabilities, video processing capabilities, etc. This disclosure does not limit the type and processing capabilities of the graphics processor.

[0044] According to this embodiment, the graphics processor sends performance data of processing the current task to an external processing unit and receives control information from the external processing unit for adjusting the parameters of the graphics processor based on the performance data of the graphics processor. The corresponding parameters are adjusted according to the control information. Thus, even without integrating a hardware DVFS module in the graphics processor chip, the parameters of the graphics processor can be dynamically adjusted.

[0045] Furthermore, by obtaining control information from an external processing unit, compared to integrating the DVFS module into the graphics processor chip, dynamic adjustment of the graphics processor parameters can be achieved in a simpler and more flexible manner, thereby reducing costs.

[0046] Furthermore, the method of this embodiment does not require the first unit and the second unit of the graphics processor to have the ability to communicate. That is to say, even if the first unit and the second unit of the graphics processor cannot communicate, the parameters of the graphics processor can still be dynamically adjusted by the method of this embodiment. The method of this embodiment has wide applicability.

[0047] In some embodiments, the parameters of a graphics processing unit (GPU) can be various parameters related to the performance of the GPU, such as the GPU's frequency and / or voltage.

[0048] In some embodiments, the external processing unit may be various processing units with computing capabilities other than a graphics processor. For example, it may be a central processing unit (CPU) or the like.

[0049] The following example, using a CPU as the external processing unit and frequency and voltage as parameters, illustrates the method for adjusting parameters. It is understood that the following explanation also applies when the external processing unit is another type of processing unit, or when the parameters are other types of parameters.

[0050] Figure 2 This is a schematic diagram of a system for adjusting parameters according to an embodiment of the first aspect of this application. Figure 2 As shown, in the system 100 for adjusting parameters, the first unit 11 of the GPU 10 is used to determine the first performance data of the GPU 10 when processing the current task. This first unit 11 is, for example, a scheduling unit of the GPU 10. This scheduling unit can be used for task scheduling and performance data monitoring of the GPU 10. However, this application is not limited to this; the first unit 11 can also be other components in the GPU 10 capable of acquiring the first performance data of the GPU 10.

[0051] In some embodiments, the first performance data of GPU 10 can be various data capable of representing the performance of GPU 10. For example, the first performance data can be the ratio of the time that GPU 10's core 13 is invoked to the specified time within a given period. For instance, if core 13 is invoked for 500ms within 1 second, the first performance data is 50%. Alternatively, the first performance data could also be the result of a counter related to the busy level of core 13, etc.

[0052] In some embodiments, such as Figure 2 As shown, the second unit 12 of GPU 10 is used to adjust the voltage and frequency of GPU 10. This second unit 12 is, for example, a management unit of GPU 10. This management unit can be used to manage the GPU 10's PMIC (Power Management IC) 14, clock module 15, power management module (not shown), etc. Among them, PMIC 104 and clock module 15 are used for voltage configuration and clock (frequency) adjustment of GPU 10, respectively.

[0053] In some embodiments, the first unit 11 of the GPU 10 can communicate with the CPU 20 through various communication protocols. For example, the first unit 11 can encapsulate first performance data according to the CCB communication protocol and send the encapsulated data to the CPU 20.

[0054] In some embodiments, the second unit 12 of the GPU 10 can communicate with the CPU 20 through various communication protocols. For example, the second unit 12 can receive control information from the CPU 20 according to the IPC communication protocol and parse the control information.

[0055] In some embodiments, such as Figure 2 As shown, CPU 20 is used to determine control information based on the first performance data. This function of CPU 20 can be implemented through a driver installed in CPU 20, that is, by determining the control information for dynamically adjusting the voltage and frequency of GPU 10 in software. Compared to hardware methods, determining the control information in software makes the dynamic adjustment of voltage and frequency more flexible and easier to adjust, and the implementation method is simpler, reducing implementation costs.

[0056] In some embodiments, the control information may include various information related to adjusting the voltage and frequency of the GPU 10. For example, the control information may include at least one of the following: information representing first performance data, information representing second performance data of the GPU 10 when processing the next task, and information related to target values ​​for the parameters of the GPU 10.

[0057] The following example illustrates a method for dynamically adjusting voltage and frequency, using control information including information representing first performance data.

[0058] When the control information includes information representing first performance data, in operation 102, the CPU 20 uses the received first performance data as control information and sends the control information to the second unit 12 of the GPU 10. For example, the CPU 20 parses the received information according to the CCB protocol to obtain the first performance data, encapsulates the first performance data according to the IPC protocol, and sends the encapsulated data to the second unit 12. Thus, the first unit 11 and the second unit 12 of the GPU 10 can communicate with each other through the CPU 20, and even when there is no communication connection between the first unit 11 and the second unit 12, dynamic adjustment of the voltage and frequency of the GPU 10 can be achieved.

[0059] Figure 3 This is a schematic diagram of the operation flow of operation 103 according to an embodiment of the first aspect of this application. Figure 3 As shown, when the control information includes information representing first performance data, operation 103 includes:

[0060] Operation 301: The second unit 12 predicts the second performance data of GPU 10 when processing the next task based on the first performance data in the control information; and

[0061] Operation 302: The second unit 12 adjusts the parameters of GPU 10 based on the second performance data.

[0062] In GPU 10, by predicting the second performance data of GPU 10 when processing the next task based on the first performance data in the control information, and adjusting the voltage and frequency of GPU 10 according to the predicted second performance data, the voltage and frequency of GPU 10 can be dynamically and timely adjusted so that GPU 10 processes the next task at an appropriate voltage and frequency.

[0063] In some embodiments, during operation 301, the second unit 12 can predict the second performance data in various ways. For example, a target performance data for GPU 10 can be set, and when the first performance data of GPU 10 is less than the target performance data, the second performance data can be made greater than the first performance data; when the first performance data is greater than the target performance data, the second performance data can be made less than the first performance data.

[0064] For example, if the first performance data of GPU 10 is less than the target performance data, the second performance data can be a value greater than the first performance data and less than or equal to the target performance data. For example, the second performance data can be obtained by adding a first preset value to the first performance data.

[0065] When the first performance data of GPU 10 is greater than the target performance data, the second performance data can be a value that is less than the first performance data and greater than or equal to the target performance data. For example, the second performance data can be obtained by subtracting a second preset value from the first performance data. The first and second preset values ​​can be the same or different, and they can be values ​​related to the first and target performance data.

[0066] For example, if the target performance data is 85%, and the first performance data is 25%, the second performance data can be set as the midpoint between the target performance data and the first performance data, for example, 55%.

[0067] However, this application is not limited to this; other methods can also be used to predict the second performance data. For example, a machine learning model can be trained using historical data, and the trained machine learning model can be used to predict the second performance data based on the first performance data. Alternatively, the trend of the collected first performance data and previously collected performance data can be compared, and the second performance data can be estimated based on the comparison results.

[0068] In some embodiments, during operation 302, after the second unit 12 obtains the second performance data, it can determine the target values ​​of the parameters of the GPU 10 corresponding to the second performance data in various ways. For example, the second unit 12 can determine the target values ​​of the parameters of the GPU 10 based on the second performance data and a pre-stored lookup table, and adjust the current parameters of the GPU 10 to the target values. The lookup table can be a table that includes a mapping relationship between the performance data of the GPU 10 and the target values ​​of the parameters.

[0069] In some embodiments, the lookup table can be set for the GPU 10 itself. For example, during GPU chip manufacturing, different performance data of the GPU chip can be tested to determine the appropriate voltage and frequency corresponding to that performance data. Since the characteristics of different chips may vary, even different chips of the same model may have different voltages and frequencies at the same performance point. Therefore, setting a lookup table suitable for each chip can further ensure chip performance and reduce power consumption.

[0070] In some embodiments, the lookup table can be stored in the memory 16 of the GPU 10. For example, it can be stored in the SRAM of the second unit 12 of the GPU 10. This allows the second unit 12 to retrieve the lookup table at high speed, thereby improving the speed of determining the target values ​​of voltage and frequency. Furthermore, compared to a hardware register lookup table, storing the lookup table in software allows for flexible modification of its contents, facilitating adjustments or updates. This application is not limited to this; the lookup table can also be stored in the CPU 20, or both the GPU 10 and the CPU 20 can be stored in the CPU.

[0071] In some embodiments, during operation 302, the second unit 12 can adjust the voltage and frequency of the GPU 10 at various times. For example, the second unit 12 can wait for and detect the idle state of the GPU 10's core 13. When the core 13 is idle, the second unit 12 configures the frequency of the GPU 10 through the clock module 15 and controls the PMIC 14 through the I2C / GPIO / PWM interface to configure the voltage of the GPU 10. This ensures the stability of the core 13's operation.

[0072] Figure 4 This is another schematic diagram illustrating a method for adjusting parameters of a graphics processor according to an embodiment of the first aspect of this application. Figure 4As shown, the first unit 11 of GPU 10 sends the first performance data to CPU 20. CPU 20 forwards the first performance data to the second unit 12 of GPU 10. The second unit 12 generates second performance data based on the first performance data, determines the target values ​​of voltage and frequency based on the second performance data and a pre-stored lookup table, and adjusts the voltage and frequency of GPU 10 based on the target values.

[0073] The following example illustrates a method for dynamically adjusting voltage and frequency, using control information that includes second performance data representing the GPU 10's performance when processing the next task.

[0074] When the control information includes information representing second performance data of the GPU 10 when processing the next task, in operation 102, the CPU 20 can predict the second performance data based on the received first performance data and send the second performance data as control information to the second unit 12 of the GPU 10. The method by which the CPU 20 predicts the second performance data based on the first performance data can be referenced from the method by which the second unit 12 predicts the second performance data; this part is incorporated here and will not be elaborated further.

[0075] In operation 103, after the second unit 12 receives control information containing second performance data, it can determine the target value of the parameters of GPU 10 based on the second performance data and a pre-stored lookup table, and adjust the current parameters of GPU 10 to the target value. The method by which the second unit 12 determines the target value of the parameters and adjusts the parameters according to the target value can be referred to the method described in operation 302, and this part is incorporated here without further elaboration.

[0076] Figure 5 This is another schematic diagram illustrating a method for adjusting parameters of a graphics processor according to an embodiment of the first aspect of this application. Figure 5 As shown, the first unit 11 of GPU 10 sends the first performance data to CPU 20. CPU 20 predicts and generates the second performance data based on the first performance data, and sends the second performance data as control information to the second unit 12 of GPU 10. The second unit 12 determines the target values ​​of voltage and frequency based on the second performance data and a pre-stored lookup table, and adjusts the voltage and frequency of GPU 10 according to the target values.

[0077] The following example illustrates a method for dynamically adjusting voltage and frequency, using control information that includes target values ​​related to the parameters of the GPU 10.

[0078] In some embodiments, the information related to the target value of the parameters of GPU 10 may include at least one of the following: an index in a pre-stored lookup table of the target value of the parameter corresponding to the second performance data, and the target value of the parameter corresponding to the second performance data in the lookup table. By including the index of the target value in the control information, the amount of data in the control information can be reduced, thereby reducing the communication burden between CPU 20 and the second unit 12 of GPU 10; by including the target value in the control information, the target value of the parameter can be directly notified to the second unit 12 of GPU 10, so that GPU 10 can directly adjust the parameters according to the target value, and the lookup table does not need to be stored in GPU 10.

[0079] Figure 6 This is a schematic diagram of the operation 102 of an embodiment of the first aspect of this application. Figure 6 As shown, when the information related to the target value of the parameters of GPU 10 includes the index of the target value, operation 102 includes:

[0080] Operation 601: Predict the second performance data of GPU 10 when processing the next task based on the first performance data;

[0081] Operation 602: Determine the index based on the second performance data and the pre-stored lookup table, and include the index in the control information; and

[0082] Operation 603: Send the control information to the second unit 12 of GPU 10.

[0083] In some embodiments, where the information related to the target value of the parameters of GPU 10 includes an index of the target value, operation 103 includes: determining the target value of the parameters of GPU 10 based on the index in the control information and a pre-stored lookup table, and adjusting the current parameters of GPU 10 to the target value.

[0084] Figure 7 This is another schematic diagram illustrating a method for adjusting parameters of a graphics processor according to an embodiment of the first aspect of this application. Figure 7 As shown, the first unit 11 of GPU 10 sends the first performance data to CPU 20. CPU 20 predicts the second performance data based on the first performance data, determines the index based on the second performance data and a pre-stored lookup table, and sends control information containing the index to the second unit 12 of GPU 10. The second unit 12 determines the target values ​​of voltage and frequency based on the index in the control information and the pre-stored lookup table, and adjusts the voltage and frequency of GPU 10 according to the target values.

[0085] Figure 8This is another schematic diagram illustrating the flow of operation 102, which is an embodiment of the first aspect of this application. For example... Figure 8 As shown, when the information related to the target value of the parameters of GPU 10 includes the target value, operation 102 includes:

[0086] Operation 801: Predict the second performance data of GPU 10 when processing the next task based on the first performance data;

[0087] Operation 802: Determine the target value based on the second performance data and a pre-stored lookup table, and include the target value in the control information; and

[0088] Operation 803: Send the control information to the second unit 12 of GPU 10.

[0089] In some embodiments, where the information related to the target value of the parameters of GPU 10 includes the target value, operation 103 includes: determining the target value of the parameters of GPU 10 based on control information, and adjusting the current parameters of GPU 10 to the target value.

[0090] Figure 9 This is another schematic diagram illustrating a method for adjusting parameters of a graphics processor according to an embodiment of the first aspect of this application. Figure 9 As shown, the first unit 11 of GPU 10 sends the first performance data to CPU 20. CPU 20 predicts the second performance data based on the first performance data, determines the target values ​​of voltage and frequency based on the second performance data and a pre-stored lookup table, and sends control information containing the target values ​​of voltage and frequency to the second unit 12 of GPU 10. The second unit 12 adjusts the voltage and frequency of GPU 10 according to the target values ​​of voltage and frequency in the control information.

[0091] It is worth noting that the above appendix Figure 1 , Figures 3 to 9 The embodiments described herein are merely illustrative and are not limited thereto. For example, the execution order of various operations can be appropriately adjusted, and additional operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above description, and are not limited to the above-described embodiments. Figure 1 , Figures 3 to 9 The records.

[0092] According to this embodiment, the graphics processor sends performance data of processing the current task to an external processing unit and receives control information from the external processing unit for adjusting the parameters of the graphics processor based on the performance data of the graphics processor. The corresponding parameters are adjusted according to the control information. Thus, even without integrating a hardware DVFS module in the graphics processor chip, the parameters of the graphics processor can be dynamically adjusted.

[0093] Furthermore, by obtaining control information from an external processing unit, compared to integrating the DVFS module into the graphics processor chip, dynamic adjustment of the graphics processor parameters can be achieved in a simpler and more flexible manner, thereby reducing costs.

[0094] Furthermore, the method of this embodiment does not require the first unit and the second unit of the graphics processor to have the ability to communicate. That is to say, even if the first unit and the second unit of the graphics processor cannot communicate, the parameters of the graphics processor can still be dynamically adjusted by the method of this embodiment. The method of this embodiment has wide applicability.

[0095] Second aspect of the embodiments

[0096] The second aspect of the embodiment provides a system for dynamically adjusting parameters. This system for dynamically adjusting parameters corresponds to the method for dynamically adjusting parameters of a graphics processor in the first aspect of the embodiment, and the same content is incorporated herein by reference and will not be described again here.

[0097] Figure 10 This is a schematic diagram of a system for dynamically adjusting parameters according to an embodiment of the second aspect of this application. Figure 10 As shown, the system 1000 for dynamically adjusting parameters includes a graphics processor 1001 and an external processing unit 1002. Specifically, a first unit 1001-1 of the graphics processor 1001 determines first performance data of the graphics processor 1001 when processing the current task and sends the first performance data to the external processing unit 1002; the external processing unit 1002 determines control information based on the first performance data and sends the control information to a second unit 1001-2 of the graphics processor 1001; the second unit 1001-2 of the graphics processor 1001 adjusts the parameters of the graphics processor 1001 according to the control information.

[0098] The graphics processor 1001 corresponds to the image processor of the first aspect embodiment, and the external processing unit 1002 corresponds to the external processing unit of the first aspect embodiment.
