In the present embodiment, the chip includes a plurality of subsystems such as a central processing unit 1 (CPU-1), a digital signal processing subsystem (DSP subsystem, abbreviated as DSP), a graphics processor 1 (GPU-1), a central processing unit 1 (DPU-1), a Universal Serial Bus (USB), a UNIX File System (UFS), and the like. Each subsystem has different functional and performance requirements. As shown in fig. 2, the multiple subsystems are divided into multiple voltage regions or power domains in order to reduce the dynamic power consumption of the chip.
The chip has a plurality of operating modes, such as an operation mode/sleep mode, etc. The subsystem has different requirements for voltage in different modes of operation. The subsystem is in a high voltage power state in the run mode, while the subsystem is switched to a lower operating voltage in the sleep mode. To meet the different voltage requirements of the subsystems, voltage conversion is typically implemented using an on-chip voltage conversion module (e.g., DC-DC/LDO). One or more voltage conversion modules may be provided for each power domain.
In this embodiment, the voltage conversion control module is configured to control the voltage output by the voltage conversion module. The voltage conversion control module is connected with a Central Processing Unit (CPU) through a control bus.

By configuring different voltage configuration parameters, the operating voltage of the target subsystem in different operating modes can be satisfied, for example, 1.2V voltage is provided in the operating mode, and 0.8V voltage is provided in the sleep mode.
In some embodiments, the voltage configuration parameters may also be configured by the CPU, which then sends the voltage configuration parameters to the voltage conversion control module, such that the voltage conversion control module directly obtains the voltage configuration parameters.
And S103, controlling the voltage conversion module corresponding to the target subsystem to output voltage according to the voltage configuration parameters.

In some embodiments, the voltage monitoring result of the voltage monitoring module corresponding to the target subsystem may be obtained through the voltage status sampling circuit. The voltage monitoring result includes, but is not limited to, voltage (true output voltage) output by the voltage conversion module, voltage state information including, but not limited to, voltage normal state information, voltage warning state information, and voltage error state information.
In some embodiments, as shown in FIG. 2, a voltage monitoring control module may be provided to control the voltage monitoring module. The voltage monitoring control module is connected with the CPU through a control bus. The CPU accesses the voltage monitoring control module through the control bus and configures monitoring parameters of the voltage monitoring module, wherein the monitoring parameters comprise, but are not limited to, monitoring voltage, threshold value of overvoltage error, overvoltage warning threshold value, threshold value of undervoltage error and undervoltage warning threshold value. The monitoring voltage is the target voltage, and the threshold value of the overvoltage error, the threshold value of the overvoltage warning, the threshold value of the undervoltage error and the threshold value of the undervoltage warning can be set according to actual needs, for example, the threshold value of the overvoltage error is set to be 110% of the target voltage, the threshold value of the overvoltage warning is 101% of the target voltage, the threshold value of the undervoltage error is 90% of the target voltage, and the threshold value of the undervoltage warning is 99% of the target voltage. The voltage monitoring control module sends the monitoring parameters of the voltage monitoring module to the voltage monitoring module, and the voltage monitoring module monitors the voltage output by the voltage conversion module in real time based on the monitoring parameters to obtain a voltage monitoring result.
S105, under the condition that the voltage monitoring result does not meet the first preset condition, adjusting the voltage configuration parameters according to the voltage monitoring result, and returning to control the voltage conversion module corresponding to the target subsystem to output voltage according to the voltage configuration parameters until the voltage monitoring result meets the first preset condition.
In some embodiments, the first preset condition comprises: the voltage output by the voltage conversion module accords with the expected voltage range.
In specific implementation, the voltage monitoring result can be analyzed by the voltage monitoring state judging circuit to judge whether the voltage monitoring result meets the first preset condition. Specifically, the voltage monitoring state judging circuit compares the voltage output by the voltage conversion module in the voltage monitoring result with the expected voltage corresponding to the target voltage, so as to determine whether the voltage output by the voltage conversion module meets the expected voltage range, namely, whether the voltage monitoring result meets the first preset condition is judged, if the voltage monitoring result does not meet the first preset condition, it is indicated that the voltage output by the voltage conversion module does not meet the requirement, then the voltage configuration parameter adaptive compensation circuit in the voltage monitoring control module can adjust the voltage configuration parameter based on the voltage monitoring result, and sends the adjusted voltage configuration parameter to the voltage conversion module, so that the voltage conversion module generates new output voltage according to the adjusted voltage configuration parameter, the voltage monitoring module monitors the new output voltage in real time, and feeds back the monitoring result to the voltage monitoring control module until the voltage output by the voltage conversion module meets the requirement. If the voltage monitoring result meets the first preset condition, the voltage output by the voltage conversion module does not need to be adjusted at the moment.
According to the voltage adjustment method provided by the embodiment of the application, the adjustment signal for adjusting the voltage of the target subsystem in the chip is obtained, and the adjustment signal comprises the target voltage to be adjusted; determining a voltage configuration parameter corresponding to the target voltage; controlling the output voltage of a voltage conversion module corresponding to the target subsystem according to the voltage configuration parameters; acquiring a voltage monitoring result of a voltage monitoring module corresponding to the target subsystem, wherein the voltage monitoring module is used for monitoring the voltage output by the voltage conversion module; under the condition that the voltage monitoring result does not meet the first preset condition, adjusting the voltage configuration parameters according to the voltage monitoring result, and returning to control the voltage conversion module corresponding to the target subsystem to output voltage according to the voltage configuration parameters until the voltage monitoring result meets the first preset condition; therefore, when the working voltage of the target subsystem in the chip is regulated, the voltage monitoring module can monitor the voltage output by the voltage conversion module corresponding to the target subsystem in real time, and the voltage conversion control module can automatically regulate the voltage configuration parameters based on the voltage monitoring result of the voltage monitoring module, so that the voltage output by the voltage conversion module corresponding to the target subsystem meets a first preset condition, the voltage output by the voltage conversion module is adaptively regulated, the voltage conversion module outputs the voltage meeting the requirement, and the chip is ensured to have higher safety.
In an optional embodiment, before the voltage monitoring result of the voltage monitoring module corresponding to the target subsystem is obtained in step S104, the voltage adjustment method further includes: determining a counting result of the clock counting module;
correspondingly, under the condition that the counting result of the clock counting module meets a second preset condition, the voltage monitoring result of the voltage monitoring module corresponding to the target subsystem is obtained.
Specifically, the voltage conversion control module is internally provided with a clock counting module. When the voltage conversion module and the voltage monitoring module start to work, the clock counting module starts to work at the same time. The second preset condition may be that the count result of the clock count module reaches a preset value. Therefore, when the counting result of the time counting module reaches a preset value, for example, 4' hF, the voltage conversion control module can collect the voltage monitoring result of the primary voltage monitoring module.
In this embodiment, by determining the counting result of the clock counting module and acquiring the voltage monitoring result of the voltage monitoring module corresponding to the target subsystem when the counting result of the clock counting module meets the second preset condition, the voltage monitoring result of the voltage monitoring module can be acquired under the condition that the voltage conversion module and the voltage monitoring module work stably, so that an accurate voltage monitoring result is obtained, and the frequency of acquiring the voltage monitoring result is reduced.
In an alternative embodiment, in step S105, adjusting the voltage configuration parameter according to the voltage monitoring result includes: determining a voltage compensation coefficient according to the voltage monitoring result; and adjusting the voltage configuration parameters according to the voltage compensation coefficient.
In one implementation, determining a voltage compensation coefficient based on the voltage monitoring result includes: under the condition that the voltage output by the voltage conversion module is overvoltage according to the voltage monitoring result, generating a negative voltage compensation coefficient according to the voltage output by the voltage conversion module and the target voltage; under the condition that the voltage output by the voltage conversion module is determined to be under-voltage according to the voltage monitoring result, generating a positive voltage compensation coefficient according to the voltage output by the voltage conversion module and the target voltage.
In specific implementation, the voltage output by the voltage conversion module in the voltage monitoring result can be compared with the target voltage to determine whether the voltage output by the voltage conversion module is overvoltage or undervoltage. When the voltage output by the voltage conversion module is overvoltage, a negative voltage compensation coefficient is generated, and the original voltage configuration parameters are subjected to negative compensation. When the voltage output by the voltage conversion module is under-voltage, a positive voltage compensation coefficient is generated, and the original voltage configuration parameters are positively compensated.
In the embodiment, by determining whether the voltage output by the voltage conversion module is overvoltage or undervoltage, a positive voltage compensation coefficient or a negative voltage compensation coefficient can be directly generated according to the actual situation of the voltage output by the voltage conversion module, so that the voltage output by the voltage conversion module is accurately compensated.
In one implementation, adjusting the voltage configuration parameter according to the voltage compensation coefficient includes: converting the format of the voltage compensation coefficient into the format of the voltage configuration parameter; and performing compensation operation on the voltage compensation coefficient and the voltage configuration parameter after the format conversion so as to adjust the voltage configuration parameter.
In the implementation, since the voltage configuration parameters are data in the complementary format, and the voltage compensation coefficients are not necessarily data in the complementary format, the voltage compensation coefficients need to be converted into data in the complementary format, and then the voltage compensation coefficients after the conversion format and the original voltage configuration parameters are subjected to compensation operation to obtain new voltage configuration parameters. The compensation operation may be embodied as an addition operation. The addition operation of the voltage compensation coefficient after the conversion format and the original voltage configuration parameter can be realized through an adder.
In this embodiment, the voltage compensation coefficient is converted into the format of the voltage configuration parameter, so that the voltage compensation coefficient can directly perform compensation operation with the voltage configuration parameter to adjust the voltage configuration parameter.
In this embodiment, by determining the voltage compensation coefficient and adjusting the voltage configuration parameter according to the voltage compensation coefficient, accurate compensation of the voltage configuration parameter can be achieved, so that the voltage conversion module can output a voltage meeting the requirement.
In an alternative embodiment, before the voltage configuration parameter is adjusted according to the voltage monitoring result in step S105, the voltage adjustment method further includes: determining voltage state information according to a voltage monitoring result;
correspondingly, under the condition that the voltage state information is voltage warning state information, adjusting the voltage configuration parameters according to the voltage monitoring result; and under the condition that the voltage state information is the voltage error state information, switching the power supply of the target subsystem to the target voltage conversion module.
In the implementation, if the voltage monitoring result has the voltage state information, the voltage state information can be directly obtained, so that the state of the voltage output by the voltage conversion module can be directly determined to be a voltage warning state or a voltage error state. When the state of the voltage output by the voltage conversion module is a voltage warning state, the voltage configuration parameters can be adjusted according to the voltage monitoring result. When the state of the voltage output by the voltage conversion module is a voltage error state, the condition that the voltage output by the voltage conversion module is too high or too low is indicated, the chip is influenced to work normally by the too high or too low voltage, the service life of the chip is even shortened, and the power supply of the chip target subsystem can be switched to another voltage conversion module or the power supply of the chip target subsystem can be realized through the chip external power supply for the purpose of chip safety.
In this embodiment, by judging that the voltage state information is the voltage warning state information and the voltage error state information, different processes can be performed according to different situations, so that when the voltage output by the voltage conversion module is too high or too low, the power supply is replaced in time, and the safety of the chip is ensured.
The voltage adjustment method of the embodiment of the present application is further described in the following specific implementation manner in the chip operation mode. The flow of the voltage regulation of the voltage system sub-module by the CPU, the voltage conversion control module, the voltage conversion module, the voltage monitoring control module and the voltage monitoring module is shown in fig. 3:
1, in an operation mode, a power management unit (Power Management Unit, PMU) starts a CPU, a voltage conversion control module, a voltage conversion module, a voltage monitoring control module and a voltage monitoring module to power up; the CPU accesses the voltage conversion control module through the control bus and configures voltage configuration parameters of the voltage conversion module to realize 1.2V output voltage; the CPU accesses the voltage monitoring control module through the control bus, configures the monitoring voltage of the voltage detection module to be 1.2V, sets the threshold value of the overvoltage error to be 1.32V (+10%), sets the threshold value of the overvoltage warning to be 1.22V (+1%), sets the threshold value of the undervoltage error to be 1.08V (-10%), and sets the threshold value of the undervoltage warning to be 1.18V (-1%).
2, a clock counting module circuit is arranged in the voltage conversion control module, when the voltage conversion module and the voltage monitoring module start to work, the clock counting module starts to work at the same time, and when the clock counting module is full of 4' hF, the voltage monitoring result of the voltage monitoring module can be acquired once. When the output voltage of the voltage conversion module accords with the expected range (1.18V-1.22V), the voltage monitoring module does not generate warning and error state information, and the voltage does not need to be regulated at the moment.
And 3, when the output voltage of the voltage conversion module is within the warning range (1.08V-1.18V/1.22V-1.32V), the voltage monitoring module generates warning state information, and after the voltage state sampling circuit in the voltage conversion control module samples the warning state information, the internal voltage monitoring state judging circuit judges whether the voltage is an overvoltage warning or an undervoltage warning.
1) When the under-voltage warning occurs, a positive compensation coefficient is generated, and the original voltage configuration parameters are positively compensated;
2) Generating a negative compensation coefficient after the overvoltage warning occurs, and realizing negative compensation on the original configuration parameters;
the voltage configuration parameter self-adaptive compensation circuit converts positive compensation coefficient or negative compensation coefficient into a complementary code format, performs compensation operation with the configuration parameter, and can realize corresponding operation function only by using one adder. And after the compensation coefficient and the configuration parameter are subjected to addition operation, obtaining a new configuration parameter, and giving the new configuration parameter to the voltage conversion module, wherein the voltage conversion module generates a new output voltage according to the compensated coefficient, and the voltage monitoring module monitors the new output voltage in real time and feeds back a voltage monitoring result to the voltage conversion control module until the voltage meets the requirement.
