Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims of the present application and in the above-described figures, are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The chips are produced in mass, and the characteristics of the chips are different due to the influence of the production process. The power supply voltage requirements required by chips of different characteristics are different when running the same load program (operating at the same frequency). In current applications, a minimum operating voltage is designed for the same lot of chips in combination with the feature profile of the lot of chips. However, for a good chip, the minimum operating voltage may be higher than the minimum operating voltage that the chip is actually adapted to, resulting in an increase in power consumption due to the excessively high supplied voltage. For example, if the minimum operating voltage set for the same batch of chips is 0.7V, the 0.7V may correspond to the worst two of the 100 chips, the voltage required for the other 98 chips is lower than 0.7V, the best possible chip is only 0.65V, and the middle chip can normally operate only 0.67V, so that the voltage is additionally 0.05V for the best chip, and power consumption is wasted. And power consumption is positively correlated with the square of voltage, the effect of voltage on power consumption is very large.
In order to solve the above problems, the present application provides a voltage regulation method, where the target operating frequency required by the load of the chip is obtained first, where the load includes an application program installed in the electronic device; inquiring a frequency voltage set of the chip according to the target working frequency, and determining a voltage value corresponding to the target working frequency, wherein the frequency voltage set comprises a corresponding relation between the working frequency and the working voltage of the chip, and the voltage value is used for representing the required working voltage of the chip at the target working frequency; then determining a target working voltage according to the voltage value; and then adjusting the working voltage of the chip to the target working voltage. Therefore, in the application, the voltage value corresponding to the target working frequency of the chip is obtained by calling the frequency voltage set of the chip, and then the working voltage of the chip is regulated according to the voltage value, so that the more proper voltage value between the chip and the target working frequency can be obtained according to the difference of the chip, and the working voltage of the chip can be regulated, thereby more pertinently optimizing the power consumption of the chip, and being beneficial to further reducing the power consumption waste.

As shown in fig. 2, the above-described chip may also be deployed with a power management framework (PM) for comprehensively managing power supply of the electronic device.
Referring to fig. 3, fig. 3 is a flowchart of a voltage regulation method according to an embodiment of the present application, and the method may be applied to a chip of an electronic device. As shown in fig. 3, the voltage adjustment method includes:
s210, acquiring a target working frequency.
The target operating frequency refers to an operating frequency required by the load operation of the chip supporting electronic equipment. The load of the electronic device may be an application program installed on the electronic device.
In a specific implementation, the dynamic frequency and voltage modulation module can detect the load condition of the electronic equipment in real time, and when the load condition changes, the dynamic frequency and voltage modulation module can acquire the target working frequency required by the changed load. For example, when the electronic device enables a certain application program, the dynamic frequency and voltage modulation module may obtain a frequency required by the chip to support the electronic device to operate after the application program is enabled, where the frequency is a target working frequency.
Specifically, the memory of the electronic device may store an application frequency set, where the application frequency set includes a correspondence between an application program and a working frequency required for the chip to support its operation. When the electronic equipment starts a certain application program, the dynamic frequency and voltage modulation module can inquire the application frequency set so as to acquire the working frequency required by starting the load, then calculates the required comprehensive working frequency according to the started application and the specific use condition of the application, and determines the comprehensive working frequency as the target working frequency.
S220, determining a voltage value corresponding to the target working frequency according to the target working frequency, wherein the voltage value is used for representing the magnitude of the working voltage required by the chip at the target working frequency.
In one possible example, the determining a voltage value corresponding to the target operating frequency according to the target operating frequency includes: acquiring a frequency voltage set of the chip; inquiring the frequency voltage set according to the target working frequency, and determining the voltage value corresponding to the target working frequency in the frequency voltage set, wherein the frequency voltage set comprises the corresponding relation between the working frequency and the working voltage of the chip.
The frequency voltage set is stored in a memory of a chip or a memory of an electronic device, and the like, and is not limited herein. The data in the frequency voltage set is the data recorded by multiple tests on the chip before the chip is assembled in the electronic equipment (such as in the chip production process). Specifically, the chip is integrated with a frequency sensor and a pressure sensor, which can record the minimum operating voltage of the chip at different operating frequencies during testing, and record the corresponding relation between the operating frequency and the operating voltage (i.e. the minimum operating voltage) in the frequency voltage set.
In a specific implementation, the set of frequency voltages for the chip may be stored in a memory of the chip. When the dynamic frequency and voltage modulation module reads the frequency and voltage set, the frequency and voltage set of the chip can be obtained by reading data in a memory of the chip. And then inquiring the corresponding voltage value in the frequency voltage set according to the target working frequency. In the example, the frequency voltage set of the chip is stored in the storage of the chip, so that the storage of the frequency voltage set is convenient, the correspondence between the frequency voltage set and the chip is stronger, and data confusion is avoided. Meanwhile, the frequency voltage set of the chip is stored in the memory of the chip, so that data loss can be avoided.
In particular, the set of frequency voltages may be stored in a tabular form. The dynamic frequency and voltage modulation module can obtain a voltage value corresponding to the target working frequency in a table look-up mode.
In this example, the voltage value corresponding to the target operating frequency of the chip is obtained by calling the frequency voltage set of the chip, and then the operating voltage of the chip is adjusted according to the voltage value, so that the operating voltage of the chip can be adjusted by obtaining the voltage value more appropriate for the chip and the target operating frequency according to the difference of the chip, thereby optimizing the power consumption of the chip more pertinently, and being beneficial to further reducing the power consumption waste.
Or, in other examples, a preset calculation formula corresponding to the chip may be configured according to a voltage frequency variation relationship of the chip, so that when the target operating frequency is obtained, the target operating frequency is brought into the preset calculation formula, so as to calculate and obtain a voltage value corresponding to the target operating frequency.
S230, determining a target working voltage according to the voltage value.
The target working voltage refers to the working voltage required by the load operation of the chip supporting electronic equipment.
In the specific implementation, the target working voltage can be equal to the voltage value, so that the consistency of the voltage value required by the chip and the actually provided target working voltage is ensured, and the accuracy of the output voltage is ensured. Or, a certain difference exists between the target working voltage and the voltage value, so that the problem of circuit aging and the like is avoided to influence the operation.
And S240, performing voltage regulation based on the target operating voltage.
In a specific implementation, after the dynamic frequency modulation voltage regulation module determines the target voltage value, a request for regulating the working voltage of the chip to the target working voltage may be generated, and the request may be sent to the AVS state machine. And then the AVS state machine sends an instruction for increasing the working voltage or reducing the working voltage to the voltage control module according to the request, so that the voltage control module is controlled to give an instruction for adjusting the working voltage of the chip to the target working voltage to the power management IC, and the working voltage of the chip is adjusted through the power management IC.
It can be seen that, in this embodiment, the target operating frequency required by the load of the chip is obtained first, where the load includes an application program installed in the electronic device; inquiring a frequency voltage set of the chip according to the target working frequency, and determining a voltage value corresponding to the target working frequency, wherein the frequency voltage set comprises a corresponding relation between the working frequency and the working voltage of the chip, and the voltage value is used for representing the required working voltage of the chip at the target working frequency; then determining a target working voltage according to the voltage value; and then adjusting the working voltage of the chip to the target working voltage. Therefore, in the application, the voltage value required by the chip is determined through the target working frequency, and the target working voltage required by the chip under the target working frequency is determined according to the voltage value, so that the voltage required by the chip is regulated based on the target working voltage, and the differential regulation for different chips can be realized, thereby being beneficial to optimizing the power consumption of the chip and reducing the power consumption.
In one possible example, the determining a voltage value corresponding to the target operating frequency according to the target operating frequency includes: and acquiring a preset voltage redundancy value of the chip, wherein the target working voltage is the sum of the voltage value and the preset voltage redundancy value.
The preset voltage redundancy value is a preset parameter, which can be calculated according to the historical use condition of the circuit, and is not limited herein.
In a specific implementation, after the voltage value is obtained, the dynamic frequency modulation and voltage regulation module can sum the voltage value and a preset voltage redundancy value, so that the target working voltage of the chip is obtained. The voltage value is the minimum working voltage of the chip under the target working frequency, which is obtained by testing the chip, and due to the voltage drop caused by the circuit board, the chip aging and other problems, in practical application, the working voltage of the chip can be adjusted more accurately by adding a preset voltage redundancy value to the target working voltage on the basis of the voltage value, so that the chip can be ensured to support the load to run.
It can be seen that, in this example, by determining the target operating voltage as the sum of the voltage value and the preset voltage redundancy value, the voltage drop caused by the circuit board and the influence caused by the chip aging can be avoided, thereby improving the accuracy of the chip operating voltage adjustment.
In one possible example, before the determining the voltage value corresponding to the target operating frequency according to the target operating frequency, the method further includes: judging whether the target working frequency is equal to a current frequency value or not, wherein the current frequency value is used for representing the current working frequency of the chip; and when the target working frequency is not equal to the current frequency value, executing the step of determining a voltage value corresponding to the target working frequency according to the target working frequency.
The current frequency value is the working frequency currently used by the chip.
In a specific implementation, referring to fig. 4, when the dynamic frequency modulation voltage regulation module detects that the load of the electronic device changes, the target working frequency can be obtained first, so as to determine the frequency required by the load operation after the chip support changes. And then comparing the target working frequency with the current frequency value. If the target operating frequency is equal to the current frequency value, the fact that the load is changed indicates that the operating frequency of the chip supporting load operation is not changed, and the operating frequency and the operating voltage of the chip do not need to be changed at the moment, namely, actions do not need to be performed for the load change at the moment. If the working frequency is not equal to the current frequency value of the chip, the change of the load is indicated to influence the working frequency and the working voltage required by the chip, the working frequency required by supporting the current load to operate is determined to be the target working frequency, the voltage value corresponding to the target working frequency is queried in the frequency voltage set of the chip by referring to the scheme, the voltage value and the preset voltage redundancy value are summed to obtain the target working voltage, and then the working voltage of the chip is regulated according to the target working voltage.
It can be seen that in this example, by adjusting the operating frequency and operating voltage before. The working frequency of the chip is determined whether to be changed or not by comparing the target working frequency with the current frequency value, so that the working frequency and the working voltage of the chip are adjusted when the working frequency is changed.
In one possible example, the performing voltage adjustment based on the target operating voltage includes: comparing the target working frequency with a current frequency value; when the target working frequency is smaller than the current frequency value, the current frequency value is reduced to the target working frequency, and then the working voltage of the chip is regulated to be the target working voltage; when the target working frequency is larger than the current frequency value, the working voltage of the chip is adjusted to be the target working voltage, and then the current frequency value is increased to the target working frequency.
In a specific implementation, referring to fig. 4, when the target operating frequency and the current frequency value are inconsistent, it indicates that the operating frequency and the operating voltage of the chip need to be adjusted. When the working frequency and the working voltage of the chip are adjusted, the voltage value determined according to the target working frequency and the preset voltage redundancy value can be summed to obtain the target working voltage. And then comparing the target working frequency with the current frequency value, if the target working frequency is larger than the current frequency value, the working frequency of the chip needs to be increased, and at the moment, the current working voltage of the chip needs to be adjusted to be the target working voltage, and then the current frequency value of the chip is adjusted to be the target working frequency, so that the purposes of boosting and then increasing the frequency are achieved. If the target working frequency is smaller than the current frequency value, the working frequency of the chip needs to be reduced, and at the moment, the current frequency value of the chip needs to be adjusted to the target working frequency, and then the working voltage of the chip is adjusted to the target working voltage, so that the frequency reduction and the voltage reduction are realized.
Specifically, after the dynamic frequency modulation voltage regulation module obtains the target operating frequency and the target operating voltage, a frequency modulation voltage regulation request may be sent to the AVS state machine, where the frequency modulation voltage regulation request carries the target operating frequency and the target operating voltage. After receiving the frequency modulation and voltage regulation request, the AVS state machine can compare the target working frequency with the current frequency value, and then send a voltage regulation command to the voltage control module according to the comparison result so as to call the power management IC to regulate the working voltage of the chip. The chip may further include a clock module (not shown), and after the AVS state machine receives the fm voltage adjustment request, a frequency adjustment command may be sent to the clock module according to the comparison result, so as to adjust the working frequency of the chip.
For example, if the target operating frequency is greater than the current frequency value, that is, when the frequency needs to be increased and the voltage needs to be boosted, the AVS state machine may first send a voltage adjustment instruction to the voltage control module to adjust the operating voltage of the chip, and then send a frequency adjustment instruction to the clock module when receiving a message that the operating voltage of the chip sent by the sensor control module has been adjusted to the target operating voltage, so as to readjust the operating frequency of the chip, so as to ensure accuracy of the adjustment sequence.
It can be seen that in this example, when the target operating frequency and the current frequency value are not equal, the magnitudes of the target operating frequency and the current frequency value may be determined, so as to determine whether the chip needs to increase the frequency and increase the voltage or decrease the frequency and decrease the voltage. Therefore, the voltage is firstly increased and then the frequency is increased when the frequency is increased and the voltage is increased, so that optimal performance power consumption optimization is safely realized, and the frequency is firstly reduced and then the voltage is reduced when the frequency is reduced and the voltage is reduced, so that the optimization of the power consumption of the chip is realized.
In one possible example, when the target operating frequency is greater than the current frequency value, before the adjusting the operating voltage of the chip to the target operating voltage, the method further includes: comparing the target working frequency with the current frequency value again; if the target working frequency is larger than the current frequency value, adjusting the working voltage of the chip to the target working voltage, and then increasing the current frequency value to the target working frequency; and if the target working frequency is smaller than the current frequency value, executing the step of raising the current frequency value to the target working frequency.
In particular, referring to fig. 4, when it is determined that the target operating frequency is greater than the current frequency value, i.e., after it is determined that an up-conversion boost is required. Before the working voltage of the chip is regulated, the target working frequency and the current frequency value can be compared again, so that the accuracy is improved. And then when the target working frequency is larger than the current frequency value as a result of reconfirmation, adjusting the working voltage of the chip to be the target working voltage, and adjusting the working frequency of the chip to be the target working frequency. If the target working frequency is smaller than the current frequency value as the reconfirming result, the comparison result is doubtful, and the frequency and voltage modulation process can be finished by adjusting the working frequency of the chip to the target working frequency at the moment without adjusting the working voltage of the chip.
It can be seen that in this example, when the target operating frequency is greater than the current frequency value, the accuracy and reliability of the operating voltage adjustment of the chip can be improved by confirming the magnitudes of the target operating frequency and the current frequency value again before adjusting the operating voltage of the chip.
In one possible example, when the target operating frequency is less than the current frequency value, before the adjusting the operating voltage of the chip to the target operating voltage, the method further includes: again comparing the target working frequency with the current frequency value; and when the target working frequency is larger than the current frequency value, adjusting the working voltage of the chip to the target working voltage.
In particular, referring to fig. 4, when it is determined that the target operating frequency is less than the current frequency value, that is, after it is determined that the frequency reduction and voltage reduction are required. The working frequency of the chip can be adjusted to be the target working frequency, and then the target working frequency and the current frequency value are compared again before the working voltage of the chip is adjusted. If the target working frequency is larger than the current frequency value, the result of the previous comparison is doubtful, and the frequency and voltage regulation process can be directly ended at the moment. If the target working frequency is smaller than the current frequency value as a result of the reconfirmation, the working voltage of the chip can be adjusted to be the target working voltage.
It can be seen that in this example, when the target operating frequency is smaller than the current frequency value, by confirming the magnitudes of the target operating frequency and the current frequency value again before adjusting the operating voltage of the chip, the accuracy and reliability of the operating voltage adjustment of the chip can be improved.
