Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a flowchart of a voltage regulation method provided by an embodiment of the present invention. The voltage regulation method includes:

Use the preset voltage regulation relationship to adjust the power supply voltage of the integrated chip;

The process of creating the preset voltage regulation relationship includes:

Step S11: acquiring the target demand voltage corresponding to the integrated chip at the target operating frequency, and recording the mapping relationship between the target operating frequency and the target demand voltage;

Step S15: Adjust the mapping relationship according to the target power supply voltage, the voltage regulation error and the target voltage difference to obtain a preset voltage regulation relationship.

In this embodiment, in order to reduce the power consumption of the integrated chip during the working process, a method for regulating the voltage of the integrated chip is provided, and the method can significantly improve the power supply and voltage regulation process of the integrated chip. Accuracy and reliability. Specifically, in the voltage regulation method, a preset voltage regulation relationship is used to adjust the power supply voltage of the integrated chip.

Among them, in the process of creating the preset voltage regulation relationship, the first step is to obtain the target demand voltage V corresponding to the integrated chip at the target operating frequency f, and record the mapping relationship between the target operating frequency f and the target demand voltage V f→ V. It should be noted that, in this embodiment, creating the mapping relationship f→V is a relatively common technical means for those skilled in the art. Therefore, in this embodiment, the specific creation process of the mapping relationship f→V will not be described in detail.

In practical applications, in addition to the operating frequency of the integrated chip, which affects the power supply voltage of the integrated chip, there are many factors that also affect the power supply voltage of the integrated chip, such as: the number of running cores in the integrated chip, the external voltage regulation in the integrated chip The voltage regulation error of the circuit to the integrated chip and the target voltage difference between the internal and external voltages of the integrated chip caused by the integrated chip manufacturing process, etc. Therefore, in this embodiment, in order to provide a more accurate power supply voltage for the integrated chip, the The mapping relationship is adjusted and corrected according to the number of cores in the integrated chip, the voltage regulation error of the external voltage regulation circuit, and the target voltage difference between the internal and external voltages of the integrated chip.

It can be understood that the increase in the number of running cores in the controller can improve the overall performance of the integrated chip, but it will also increase the power consumption of the integrated chip. Therefore, the number of running cores in the integrated chip will also affect the created Mapping relationship affects. Therefore, in this embodiment, in order to make the mapping relationship more reliable and accurate, it is also necessary to modify the mapping relationship according to the change in the number of cores in the integrated chip. In this process, it is first necessary to obtain the target power supply voltage required by the integrated chip when the number of cores is N. Assuming that the integrated chip needs to increase the power supply voltage by ΔV _α every time an operating core is added, the target power supply voltage required by the integrated chip when the number of cores is N is V _N =V+ΔV _α ·N.

Secondly, in the process of using the external voltage regulating circuit in the integrated chip to adjust the power supply voltage of the integrated chip, the difference in the properties of the external voltage regulating circuit itself will also affect the power supply voltage of the integrated chip. Therefore, in this implementation In the example, in order to provide a more accurate power supply voltage to the integrated chip, the voltage regulation error V _x of the external voltage regulation circuit when supplying power to the integrated chip _is further obtained. The adjustment value set by the property characteristics of the voltage regulator circuit.

In addition, since the integrated chip is limited by the manufacturing process, transistors in different positions in the integrated chip will also have great differences in performance, which will lead to inconsistent operation time required by the same logic block in the integrated chip; The internal transistor performance of an integrated chip will also vary in different environments. For example, the higher the temperature, the greater the leakage current in the integrated chip, resulting in the voltage drop value in the process of supplying power to the integrated chip. bigger. That is, under different ambient temperatures, the same external power supply voltage will be different when it finally reaches the internal controller of the integrated chip. Therefore, when adjusting the power supply voltage of the integrated chip, it is also necessary to consider the target voltage difference between the external power supply voltage of the integrated chip and the actual power supply voltage.

In this embodiment, in order to avoid the influence of the voltage drop value inside the integrated chip on the power supply voltage of the integrated chip, the target voltage difference between the internal and external voltages of the integrated chip is also determined according to the external power supply voltage of the integrated chip and the actual power supply voltage. That is, assuming that the actual power supply voltage of the integrated chip is V ₁ , its external power supply voltage is V ₂ , and the actual power supply voltage of the integrated chip is V ₃ , then the target voltage difference of the integrated chip is (V ₂ -V ₃ ), after considering the target voltage difference between the internal and external voltages of the integrated chip, the target voltage difference can be used to adjust and correct the mapping relationship. At this time, the actual power supply voltage for the integrated chip is: V _β =V ₁ +(V ₂ -V ₃ ).

In summary, after obtaining the target power supply voltage, the voltage regulation error when the external voltage regulation circuit supplies power to the integrated chip, and the target voltage difference between the internal and external voltages of the integrated chip, the target power supply voltage, the voltage regulation error and the target voltage can be used. The target pressure difference is used to adjust and correct the mapping relationship to obtain a preset pressure regulation relationship. Among them, in the process of adjusting the mapping relationship by using the target power supply voltage, the voltage regulation error and the target voltage difference, the target demand voltage in the mapping relationship is mainly adjusted by using the target power supply voltage, the voltage regulation error and the target voltage difference. and correction, so that the required voltage of the integrated chip at the target operating frequency can be more accurate and reliable.

It should be noted that, in the process of adjusting the mapping relationship by using the target power supply voltage, voltage regulation error and target voltage difference, the order before and after the adjustment of each factor is not specifically limited, as long as the target power supply voltage, voltage regulation error and target voltage are used. The pressure difference can adjust and correct the mapping relationship together.

For example: when the target supply voltage V _N =V+ΔV _α ·N is used to correct the target demand voltage V in the mapping relationship, the first corrected mapping relationship will be obtained: f→V+ΔV _α ·N; then, When using the voltage regulation error V _x to correct the demanded voltage in the first correction mapping relationship, the second correction mapping relationship will be obtained: f→V+ΔV _α ·N+V _x ; finally, using the target voltage difference (V ₂ -V ₃ ) to correct and adjust the demand voltage in the second correction mapping relationship, the third correction mapping relationship is obtained: f→V+ΔV _α ·N+V _x +(V ₂ -V ₃ ).

It can be seen that, in the voltage regulation method provided in this embodiment, the target demand voltage corresponding to the integrated chip at the target operating frequency is first obtained, and the mapping relationship between the target operating frequency and the target demand voltage is recorded; The target power supply voltage required by the chip when the number of cores is N, and the voltage regulation error of the external voltage regulation circuit when supplying power to the integrated chip is set according to the attribute characteristics of the external voltage regulation circuit of the integrated chip, and the voltage regulation error of the integrated chip is used at the same time. The target voltage difference of the integrated chip is determined by the external power supply voltage and the actual power supply voltage; after that, the mapping relationship is adjusted according to the target power supply voltage, voltage regulation error and target voltage difference to obtain a preset voltage regulation relationship; The voltage relationship is used to adjust the power supply voltage of the integrated chip. Obviously, in the voltage regulation method provided in this embodiment, because the difference in the manufacturing process of the integrated chip, the voltage regulation error of the external voltage regulation circuit and the influence of the change in the number of operating cores inside the integrated chip on the power supply voltage of the integrated chip are considered, Therefore, by using this method, the accuracy and reliability in the process of power supply voltage regulation for the integrated chip can be significantly improved.

Specifically, in this embodiment, the integrated chip is set as an SOC chip. Because the SOC chip can effectively reduce the development cost and development cycle of electronic products, it is widely used in real life. Therefore, in this embodiment, the integrated chip is set as an SOC chip, so that the universality of the voltage regulation method provided by the present application in the actual use process can be relatively improved.

Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation, the process of adjusting the power supply voltage of the integrated chip by using the preset voltage regulation relationship includes:

In practical applications, if the adjustment range of the power supply voltage of the integrated chip is too large, it may cause a huge change in the ripple of the external voltage regulating circuit of the integrated chip. In this case, the power supply voltage to the controller may not be controlled. within the range. Therefore, in this embodiment, in order to avoid the above situation, a preset voltage regulation relationship is used to uniformly adjust the power supply voltage of the integrated chip, so as to ensure the reliability in the process of supplying power to the integrated chip.

That is, if the voltage that needs to supply power to the integrated chip is V1, and the current supply voltage to the integrated chip is V2, in order to ensure the stability in the process of supplying power to the integrated chip, a step-up or step-down method can be adopted. to adjust the power supply voltage of the integrated chip.

Specifically, in the process of uniformly adjusting the power supply voltage of the integrated chip by using the preset voltage regulation relationship, the power supply voltage of the integrated chip can also be adjusted based on the voltage regulation response time of the integrated chip, because when the power supply voltage of the integrated chip is based on the When the power supply voltage of the integrated chip is adjusted by the voltage regulation response time, the voltage jitter phenomenon that occurs in the process of voltage regulation of the integrated chip can be avoided, thereby ensuring the integrity of the voltage regulation process of the integrated chip. sex.

The maximum power supply voltage V _max of the power supply, and then, according to the properties and characteristics of the external voltage regulator circuit, the voltage regulation error coefficient δ of the external voltage regulator circuit when supplying power to the integrated chip is set, and finally, according to the maximum power supply voltage V _max and the regulation The voltage error coefficient δ determines the voltage regulation error V _max ·δ. It is conceivable that after the voltage regulation error V _max ·δ is determined, the mapping relationship can be corrected by using the voltage regulation error V _max ·δ, that is, f→(V+V _max ·δ).
