In the description of the present application, it should be noted that the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.
It should be noted that, in the prior art, communication is implemented between the graphics processor and the power management circuit through the PMBUS, however, the PMBUS can only work at a working rate of 1MHz at the highest, and at least several tens of microseconds are required for sending a PMBUS command, which results in slow speed and low efficiency of adjustment.
In addition, in actual use, the voltage can not be further adjusted until the voltage is stable, so that the voltage needs to be queried by sending a command, and further time is consumed. Meanwhile, the adjustment of each power supply module has a sequential problem, so that each power supply module cannot be adjusted at the same time, and partial power consumption waste exists in a circuit with preferential boosting or a circuit with later voltage reduction.
In order to solve the above problems in the prior art, an embodiment of the present application proposes a structure of a voltage adjustment system, and a specific structural relationship of the voltage adjustment system of an execution body performing the method and an operation principle thereof are specifically explained below.

Graphics processor 200 (GPU, graphics Processing Unit), which may be a chip for graphics processing, may include an adaptive voltage-regulated bus control unit 210 and a plurality of power supply modules 220.
The adaptive voltage regulator bus control unit 210 (AVSBus Master) may be a subunit disposed in the GPU, and may convert and transmit a data format, and may convert the format of the transmitted data into a format that the adaptive voltage regulator bus (AVSBus) may implement. For the same GPU, a plurality of power supply modules 220 may be included, different power supply modules may supply power to the functional circuits in different areas, and in the working process of the image processor, due to the actual working requirements, the areas that may need to be powered are not uniform, so that the power can be supplied to the areas that need to be powered, the areas that do not need to be powered are disconnected, or a higher power supply voltage is adopted in the areas with higher power requirements, and a lower power supply voltage is adopted in the areas with lower power requirements, so that more flexible power supply is realized, the power requirements can be reduced, the service life of the chip can be prolonged, and the like.
It should be noted that, different power supply modules can be controlled by the same PMIC, the PMIC can supply power to each power supply module through different power supply ports, and power can be supplied to each power supply module specifically according to power supply requirements.
The central controller 300 (CPU, central Processing Unit) may be a control central unit for implementing sending and receiving of each command, and specifically how to implement the power supply to each power supply module in the GPU and the obtained adjustment result are all completed by the central controller 300.

Optionally, the implementation subject of the method is the voltage adjustment system, and the whole voltage adjustment system may be in the same electronic device, for example: computers, cell phones, tablet computers, etc., are not particularly limited herein.
The first power supply adjustment command may be used to instruct to perform power supply adjustment on a power supply module in the graphics processor, and may specifically include: the identification of the power supply module that needs to be adjusted, and the target adjustment value of each power supply module that needs to be adjusted, for example: the voltage is increased, decreased, power is turned on or off, and the like, and is not particularly limited herein.

It should be noted that, since the adaptive voltage adjustment bus control unit is connected to the integrated power management circuit through the adaptive voltage adjustment bus, and the first power adjustment command is specifically transmitted through an internal custom format, format conversion is required for the first power adjustment command.
Specifically, the adaptive voltage regulation bus control unit may perform command format conversion processing on the first power supply regulation command based on format information of the adaptive voltage regulation bus to obtain a second power supply regulation command adapted to transmission of the adaptive voltage regulation bus.
That is, the first power adjustment command and the second power adjustment command are the same command characterized by different formats.
That is, the transmission command in the internal custom format may be converted into a command that may be transmitted through the AVSBus bus, which is the second power adjustment command.
After the first power supply adjustment command is converted into the second power supply adjustment command in the above manner, the second power supply adjustment command may be sent to the integrated power management circuit through the adaptive voltage adjustment bus.
S230: the voltage of at least one power supply module of the graphics processor is adjusted by the integrated power management circuit according to the second power supply adjustment command.
Optionally, after receiving the second power adjustment command, the integrated power management circuit may perform voltage adjustment on a power module of the graphics processor based on the second power adjustment command.
The number of power supply modules for which voltage adjustment is specifically required and the target adjustment value for each power supply module may be determined based on the second power supply adjustment command.
For example: if the three power supply modules need to be adjusted, the first power supply module is powered off, the second power supply module is powered up, and the third power supply module is powered down, then the integrated power management circuit can respectively execute corresponding adjustment on each power supply module.
In the power supply control method provided by the embodiment of the application, the self-adaptive voltage regulation bus control unit can receive the first power supply regulation command sent by the central controller; the self-adaptive voltage regulating bus control unit converts the first power supply regulating command into a second power supply regulating command according to the format information of the self-adaptive voltage regulating bus, and sends the second power supply regulating command to the integrated power supply management circuit through the self-adaptive voltage regulating bus; the voltage of at least one power supply module of the graphics processor is adjusted by the integrated power management circuit according to the second power supply adjustment command. The self-adaptive voltage regulation bus is used for transmitting the command, so that the integrated power management circuit can receive the corresponding power supply regulation command more quickly and efficiently, and the power supply module in the image processor can be regulated more quickly and accurately by the integrated power management circuit.
Another embodiment of the power supply control method provided in the embodiment of the present application will be specifically explained below.

s310: and receiving a third power supply adjustment command sent by the central controller by the self-adaptive voltage adjustment bus control unit.
Alternatively, the third power supply adjustment command may specifically be a command for instructing an order of adjusting the voltages of the respective power supply modules in accordance with the second power supply adjustment command.
For example: when the integrated power management circuit needs to perform power supply adjustment on the three power supply modules according to the second power supply adjustment command, the adjustment sequence of the three power supply modules can be determined through the third power supply adjustment command.
S320: and the self-adaptive voltage regulating bus control unit converts the third power supply regulating command into a fourth power supply regulating command according to the format information of the self-adaptive voltage regulating bus, and sends the fourth power supply regulating command to the integrated power supply management circuit through the self-adaptive voltage regulating bus.
Alternatively, after receiving the third power adjustment command, the adaptive voltage adjustment bus control unit may convert the third power adjustment command into a fourth power adjustment command.
Specifically, the adaptive voltage regulation bus control unit may perform command format conversion processing on the third power supply regulation command based on format information of the adaptive voltage regulation bus, to obtain a fourth power supply regulation command adapted to transmission of the adaptive voltage regulation bus.
That is, the third power adjustment command and the fourth power adjustment command are the same command characterized by different formats.
After the third power supply adjustment command is converted into the fourth power supply adjustment command in the above manner, the fourth power supply adjustment command may be sent to the integrated power management circuit through the adaptive voltage adjustment bus.
It should be noted that, in the actual execution process, the first power supply adjustment command and the third power supply adjustment command may be packaged together to perform format conversion, so as to obtain a second power supply adjustment command and a fourth power supply adjustment command that are packaged together; or, the first power supply adjustment command and the third power supply adjustment command may be sequentially sent, and the second power supply adjustment command and the fourth power supply adjustment command may be sequentially obtained after conversion.
In the power supply control method provided by the embodiment of the application, the self-adaptive voltage regulation bus control unit can receive the third power supply regulation command sent by the central controller; and the self-adaptive voltage regulating bus control unit converts the third power supply regulating command into a fourth power supply regulating command according to the format information of the self-adaptive voltage regulating bus, and sends the fourth power supply regulating command to the integrated power supply management circuit through the self-adaptive voltage regulating bus. The fourth power supply adjustment command can be used for adjusting each power supply module more flexibly, so that waste of time and power consumption which are consumed when a plurality of power supply modules need to be adjusted is avoided, and the adjustment efficiency can be further improved.
A specific implementation procedure of voltage adjustment of the power supply module based on the fourth power supply adjustment command is specifically explained below.
Optionally, adjusting, by the integrated power management circuit, a voltage of at least one power module of the graphics processor according to the second power adjustment command, including: and determining an adjustment sequence by the integrated power management circuit according to the fourth power supply adjustment command, and adjusting the voltage of the power supply module in the graphic processor based on the second power supply adjustment command in sequence according to the adjustment sequence.
Wherein the fourth power adjustment command may specifically indicate an adjustment sequence, for example: when three power supply modules (a power supply module a, a power supply module B and a power supply module C) requiring power supply adjustment exist, if the order of a→b→c indicated by the fourth power supply adjustment command, the power supply modules a, B and C may be sequentially subjected to power supply adjustment when power supply adjustment is performed.

The fourth power supply adjustment command may specifically instruct to perform power supply adjustment on all power supply modules that need to perform power supply adjustment at the same time, that is, perform parallel adjustment.
It should be noted that, the two modes adopted above may be sequentially adjusted and simultaneously adjusted, and the third power supply adjustment command may be correspondingly set based on the actual requirement, which is not limited herein, and in the actual implementation process, the two modes may be combined, for example: the power supply of the power supply modules is adjusted in a certain sequence, one power supply module is adjusted, the other power supply modules or other power supply modules can be adjusted, and the power supply adjustment can be indicated through a third power supply adjustment command.
For example: the execution sequence of each power supply module can be determined by a write hold command, a write implement command, and the like.
Optionally, after the voltage of the at least one power module of the graphics processor is adjusted by the integrated power management circuit according to the second power adjustment command, the method further comprises: if the voltage of at least one power supply module is adjusted, the integrated power supply management circuit generates a target state signal, wherein the target state signal is used for indicating that the adjustment of the graphic processor is finished, the self-adaptive voltage adjustment bus control unit monitors and acquires the target state signal of the integrated power supply management circuit, and the target state signal is sent to the central controller.
When it is determined that the voltage of all the power supply modules needing power supply adjustment is adjusted, the integrated power management circuit can generate a target state signal.
It should be noted that, if the second power supply adjustment command indicates that power supply adjustment needs to be performed on the three power supply modules, the target state signal may be generated after all the three power supply modules perform power supply adjustment and the adjustment is completed.
Optionally, the target state signal may be a digital signal, and the adaptive voltage adjustment bus control unit may monitor the target state signal through the adaptive voltage adjustment bus, and after acquiring the target state signal, may send the target state signal to the central controller, so that the central controller determines that the current power supply adjustment has been completed.
The following specifically explains the specific implementation procedure for monitoring and acquiring the target state signal provided in the embodiment of the present application.
Fig. 4 is another flow chart of a power supply control method according to an embodiment of the present application, referring to fig. 4, the generating, by an integrated power management circuit, a target status signal includes:
s410: the initial state signal on the target interface is changed to a target state signal by the integrated power management circuit.
Wherein the adaptive voltage regulating bus is connected to the target interface.
Alternatively, the integrated power management circuit may be specifically an integrated chip, and there may be a pin of the chip for outputting a status signal, for example: the pin may be connected as a target interface with the adaptive voltage regulation bus.
Specifically, the target interface may output two types of signals, such as a digital signal 0 and a digital signal 1, where the initial state signal may be the digital signal 0 and the target state signal may be the digital signal 1.
In the initial state, for example: the integrated power management circuit may determine that the integrated power management circuit is currently in an initial state when power supply adjustment is not started or is in the process of power supply adjustment, and in this state, the initial state signal may be a digital signal 0, and accordingly, after power supply adjustment is completed, the integrated power management circuit may change from the initial state signal to a target state signal, that is, from the digital signal 0 to the digital signal 1.
