[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Existing chips use a step-by-step frequency modulation method to divide the frequency / voltage into several levels. When the frequency needs to be increased, it is tested one level at a time. After configuring the previous frequency / voltage, it is determined whether the power consumption exceeds the limit. If not, the next level of frequency / voltage is configured for testing to obtain the maximum frequency under the power consumption limit to meet the performance and power consumption requirements. Similarly, when the frequency is reduced or exceeds the power consumption limit, it is also tested one level at a time. This step-by-step frequency modulation method has the problem of low frequency modulation efficiency due to step-by-step testing and judgment. When the performance requirements of the running application are high, it is necessary to increase the frequency one level at a time at a low frequency, resulting in a relatively low-frequency operation stage, resulting in poor performance. At the same time, when frequency reduction protection is needed, the frequency is reduced one level at a time. When the load is large, there is a relatively high-frequency operation stage, resulting in a slow decrease in power consumption and heat generation, which triggers over-temperature protection.

[0026] The step-by-step frequency modulation method has the defect of low frequency modulation efficiency. At the same time, it can only perform frequency modulation according to the preset frequency / voltage levels, and cannot perform frequency modulation of smaller granularity. There may be a better frequency / voltage configuration between two levels, resulting in the defect of not being able to fully utilize the performance of the chip under power consumption constraints.

[0027] With regard to the problems and defects existing in step-by-step frequency modulation, the present invention provides a chip power consumption control method, device and storage medium to solve the above problems and defects.

[0028] Combine the following Figures 1 to 4 A chip power consumption control method of the present invention is described, comprising: S100: Obtaining a target power consumption value, a current power consumption value, and a current frequency value; S200: determining a power consumption difference ratio value according to the current power consumption value and the target power consumption value; S300: acquiring a frequency increase / decrease value according to the current frequency value and the power consumption difference ratio value, wherein the frequency increase / decrease value is positively correlated with the power consumption difference ratio value; S400: determining a target frequency value according to the frequency increase / decrease value and the current frequency value; S500: Adjusting the operating frequency and the operating voltage according to the target frequency value.

[0029] By obtaining the target power consumption value, the current power consumption value and the current frequency value, the power consumption difference ratio value is determined according to the difference between the current power consumption value and the target power consumption value, and then the frequency increase or decrease value is obtained by combining the power consumption difference ratio value with the current frequency value. Since the frequency increase or decrease value is positively correlated with the power consumption difference ratio value, that is, the greater the difference between the current power consumption value and the target power consumption value, the greater the frequency increase or decrease value will be, and then the target frequency value is determined according to the frequency increase or decrease value and the current frequency value, so that the operating frequency and the operating voltage are adjusted according to the target frequency value, that is, the frequency modulation process is performed, so that the operating power consumption can quickly approach the target power consumption value.

[0030] In this way, the target frequency value is obtained based on the size of the power consumption difference. There is no need to try to increase or decrease the frequency step by step. The target frequency value that meets the target power consumption value can be quickly determined. The operating frequency and operating voltage are adjusted according to the target frequency value, which is conducive to improving the frequency modulation efficiency, improving the performance and temperature control performance, and controlling the operating power consumption near the target power consumption value to meet the power consumption requirements. At the same time, a smaller granularity of frequency modulation is achieved. The operating frequency and operating voltage are adjusted according to the target frequency value, which can fully utilize the chip performance under the power consumption limit, thereby improving the utilization efficiency of the chip performance.

[0031] It should be noted that in some embodiments, the target power consumption value may be a preset maximum power consumption limit value. When running an application, model or other load, the maximum power consumption limit value is used as the target power consumption value to quickly increase the frequency to the maximum frequency that can be run under the maximum power consumption limit value, that is, the target frequency value, thereby achieving the effect of providing the best performance, which is conducive to timely meeting the performance requirements of the load. In some embodiments, the target power consumption value may also be updated based on the operating conditions of the chip, such as operating temperature, load level and other factors.

[0032] The current power consumption value may be obtained by collecting the current working voltage and working current, and the current frequency value may be obtained by collecting the current working frequency.

[0033] refer to Figure 2 In some embodiments of a chip power consumption control method of the present invention, the S400 includes: S410: Obtaining a calculated frequency value based on the current frequency value and the frequency increase / decrease value; S420: Determine the target frequency value according to the calculated frequency value and a preset frequency limit range.

[0034] The chip needs to operate stably within a suitable frequency range. After calculating the theoretically optimal calculated frequency value based on the current frequency value and the frequency increase or decrease value, the target frequency value is determined in combination with the actual preset frequency limit range of the chip. In this way, the target frequency value is ensured to be within the frequency limit range of the chip, and the operating frequency and operating voltage are subsequently adjusted according to the target frequency value, so that the chip can operate stably and improve reliability.

[0035] In some embodiments of a chip power consumption control method of the present invention, the S200 includes: The difference between the target power consumption value and the current power consumption value is divided by the current power consumption value to obtain a quotient as the power consumption difference ratio value.

[0036] Subtract the current power consumption value from the target power consumption value, obtain the difference between the two and divide it by the current power consumption value to obtain the power consumption difference ratio value, which can indicate the difference between the current power consumption value and the target power consumption value, and facilitate the subsequent proportional calculation to obtain the frequency increase or decrease value to achieve frequency modulation.

[0037] In some embodiments of the present invention, in addition to obtaining the power consumption difference ratio value by the above-mentioned calculation method, the difference between the target power consumption value and the current power consumption value may be divided by the target power consumption value, and the quotient may be used as the implementation method of the power consumption difference ratio value. In some embodiments, in addition to calculating the power consumption difference ratio value in a linear manner, the calculation method of the power consumption difference ratio value may be determined according to the required control curve. For example, if it is to be controlled in the form of a quadratic root curve, the power consumption difference ratio value may be obtained by dividing the difference between the target power consumption value and the current power consumption value by the current power consumption value, retaining the positive and negative signs of the quotient value and taking the absolute value of the quadratic root of the quotient value. In this way, in addition to calculating the power consumption difference ratio value in a linear manner, the power consumption difference ratio value may also be calculated by other methods such as a quadratic root curve, and the power consumption difference ratio value may be obtained according to different calculation methods so that the change curve of the power consumption difference ratio value meets the design requirements.

[0038] In some embodiments of a chip power consumption control method of the present invention, the S200 may also include: Taking the quotient of the difference between the target power consumption value and the current power consumption value divided by the target power consumption value as the first deviation value; Using the first deviation value of the previous calculation cycle as the second deviation value; Taking the difference between the first deviation value and the second deviation value as the deviation change rate; The power consumption difference ratio value is calculated and determined according to the first deviation value, the deviation change rate and a preset coefficient.

[0039] The difference between the target power consumption value and the current power consumption value is divided by the target power consumption value, and the quotient obtained is used as the first deviation value, which can reflect the degree of deviation between the current power consumption value and the target power consumption value. The first deviation value of the previous calculation cycle is used as the second deviation value, and the first deviation value of the current calculation cycle is subtracted from the second deviation value to obtain the deviation change rate, which can reflect the effect of the power consumption adjustment. According to the first error value and the deviation change rate of the current calculation cycle, combined with the preset coefficient, the power consumption difference ratio value is calculated to obtain the target frequency value obtained based on the power consumption difference ratio value, which is obtained by considering the degree of deviation of the power consumption and the adjustment effect of the previous cycle, which is conducive to making the target frequency value more accurate and improving the accuracy of frequency and power consumption control adjustment. In some embodiments of a chip power consumption control method of the present invention, S300 includes: The product of the current frequency value and the power consumption difference ratio value is used as the frequency increase or decrease value.

[0040] The current frequency value is multiplied by the power consumption difference ratio value, and the product is used as the frequency increase or decrease value to determine the amplitude value of the frequency modulation based on the power consumption difference. The larger the power consumption difference, the larger the frequency increase or decrease value, that is, the frequency increase or decrease value is positively correlated with the power consumption difference ratio value. The current frequency value changes during the power consumption and frequency adjustment process, so that the determination of the target frequency value will take the influence of the current frequency value into greater consideration.

[0041] In some embodiments of a chip power consumption control method of the present invention, the S300 may also include: The product of the power consumption difference ratio value and the preset frequency upper and lower limit difference is used as the frequency increase or decrease value.

[0042] By multiplying the preset frequency upper and lower limits by the power consumption difference ratio, and using the product as the frequency increase or decrease value, the amplitude value of the frequency modulation can also be determined based on the power consumption difference, so that the larger the power consumption difference, the larger the frequency increase or decrease value, that is, the frequency increase or decrease value is positively correlated with the power consumption difference ratio value. The preset frequency upper and lower limits are determined by the upper and lower limits of the frequency limit range, that is, they are unchanged during the power consumption and frequency adjustment process, so that the determination of the target frequency value will be more biased towards the influence of the power consumption difference ratio value.

[0043] In some embodiments of a chip power consumption control method of the present invention, the S410 includes: The calculated frequency value is obtained according to the sum of the current frequency value and the frequency increase / decrease value.

[0044] The current frequency value is added to the frequency increase or decrease value to obtain the calculated frequency value. According to the calculated frequency value, the frequency can be quickly adjusted to the maximum frequency value under the target power consumption value limit, thereby improving the frequency modulation efficiency.

[0045] In some embodiments of the present invention, in addition to the above-mentioned calculation method for obtaining the frequency increase and decrease value and calculating the frequency value, it is also possible to add weights, constants and other adjustment items for calculation based on the above-mentioned calculation method according to actual adjustment needs, so that the change curves of the frequency increase and decrease value and the calculated frequency value are more in line with the needs.

[0046] It is understandable that the calculated frequency value is the maximum frequency value under the theoretical target power consumption value limit, but it is necessary to comprehensively consider the frequency limit range of stable chip operation to determine the optimal target frequency value. The positive and negative signs of the difference between the target power consumption value and the current power consumption value are consistent with the positive and negative signs of the frequency increase and decrease value, so that the frequency can be increased when the target power consumption value is not reached, and the frequency can be reduced when the target power consumption value is exceeded.

[0047] In some embodiments of a chip power consumption control method of the present invention, the S100 includes: Acquire the target power consumption value and acquire the current power consumption value and the current frequency value according to a preset interval period; Wherein, each time the current power consumption value and the current frequency value are obtained according to the preset interval period, the target frequency value is correspondingly determined once.

[0048] Since the operating state of the chip is constantly changing, the current power consumption value and the current frequency value are periodically updated according to the preset interval period, and the calculated frequency value is obtained by combining the target power consumption value. Then, within the preset frequency limit range, the target frequency value is determined to achieve the target frequency value being updated according to the preset interval period, and then the operating frequency and the operating voltage are dynamically adjusted. When the operating state of the chip changes, the operating power consumption value can be stably kept close to the target power consumption value and run at the optimal operating frequency, which is conducive to improving stability.

[0049] refer to Figure 5 In some embodiments of a chip power consumption control method of the present invention, the current power consumption value is obtained by: According to the preset sampling time, the sampling power consumption is obtained; According to the preset interval period, an average value of the sampled power consumption within the preset interval period is calculated to obtain the current power consumption value.

[0050] According to the preset sampling time, sampling is performed periodically to obtain the sampled power consumption. According to the sampled power consumption obtained within the preset interval period, the average power consumption value is calculated as the current power consumption value, which can more accurately reflect the current power consumption and reduce the impact of power consumption fluctuations.

[0051] It is understandable that the calculation cycle corresponds to the interval cycle, that is, one calculation cycle is performed corresponding to each interval cycle to calculate and update the target frequency value. The sampling time is less than the interval cycle, that is, multiple samplings may be performed in one interval cycle.

[0052] In some embodiments of the present invention, the current power consumption value may also be based on a preset interval period, where sampling is performed only once in each interval period, and the acquired power consumption is used as the current power consumption value.

[0053] In some embodiments of the present invention, the preset interval period may be set to 1 millisecond, that is, a target frequency value is updated every 1 millisecond.

[0054] The current power consumption value and the current frequency value are updated at preset intervals, but the target power consumption value is not necessarily updated periodically. In some embodiments of the present invention, the target power consumption value may be maintained unchanged at the preset power consumption limit value to continuously provide optimal performance; in some embodiments, the target power consumption value may also be updated in response to changes in load and temperature. In this case, the update of the target power consumption value is related to the update time of the load and temperature.

[0055] refer to Figure 3 In some embodiments of a chip power consumption control method of the present invention, the S420 includes: S421: Determine an upper frequency limit and a lower frequency limit according to the frequency limit range; S422: When the calculated frequency value is greater than the frequency upper limit value, the target frequency value takes the frequency upper limit value; S423: When the calculated frequency value is less than the frequency lower limit value, the target frequency value takes the frequency lower limit value; S424: When the calculated frequency value is less than or equal to the upper frequency limit value and greater than or equal to the lower frequency limit value, the target frequency value is the calculated frequency value.

[0056] The upper frequency limit value and the lower frequency limit value of the frequency limit range are compared with the calculated frequency value. When the calculated frequency value is greater than the upper frequency limit value, the target frequency value takes the upper frequency limit value; when the calculated frequency value is less than the lower frequency limit value, the target frequency value takes the lower frequency limit value; when the calculated frequency value is between the upper frequency limit value and the lower frequency limit value, the target frequency value takes the calculated frequency value. In this way, combined with the theoretical maximum calculated frequency value under the target power consumption value limit and the frequency limit range of stable operation of the chip, the best target frequency value within the frequency limit range is obtained, which is conducive to stabilizing and fully exerting the performance of the chip.

[0057] In some embodiments of a chip power consumption control method of the present invention, the target frequency value can be calculated and obtained by the following formula:

[0058] in, To calculate the frequency value; is the current frequency value; is the target power consumption value; is the current power consumption value; is the target frequency value; is the upper frequency limit; is the lower frequency limit.

[0059] refer to Figure 5 In some embodiments of a chip power consumption control method of the present invention, a target frequency value may also be obtained through a PD controller, and the target frequency value is calculated and obtained by the following formula:

[0060] in, is the sampling power consumption; k is the number of sampling times performed at the preset sampling time within the preset interval period; is the average power consumption value, which is used as the current power consumption value; is the first deviation value; is the target power consumption value; is the deviation change rate; is the second deviation value, i.e., the first deviation value of the previous calculation cycle; PDO is the calculated value of the PD controller, which is used as the power consumption difference ratio value; P and D are the preset coefficients of the PD controller, which can be adjusted according to the needs; To calculate the frequency value; is the current frequency value; is the target frequency value; is the upper frequency limit; is the lower frequency limit; It is the difference between the upper and lower limits of the preset frequency.

[0061] refer to Figure 4 In some embodiments of a chip power consumption control method of the present invention, the S500 includes: S510: Determine a target voltage value according to the target frequency value; S520: Determine whether to increase the frequency according to the target frequency value and the current frequency value; When upscaling: S530: increasing the operating voltage according to the target voltage value; S540: increasing the operating frequency according to the target frequency value; When frequency is reduced: S550: reducing the operating frequency according to the target frequency value; S560: reducing the operating voltage according to the target voltage value.

[0062] In a stable state, the current operating frequency should be the maximum frequency that the current operating voltage can support in order to give full play to the performance. Otherwise, if the current operating frequency is not the maximum frequency of the current operating voltage, the current operating frequency can be maintained, and the operating voltage can be reduced to obtain lower power consumption and improve performance. Therefore, when determining the frequency increase based on the comparison between the target frequency value and the current frequency value, the operating voltage is first increased according to the target voltage value, and then the operating frequency is increased according to the target frequency value; when determining the frequency reduction based on the comparison between the target frequency value and the current frequency value, the operating frequency is first reduced according to the target frequency value, and then the operating voltage is reduced according to the target voltage value. In this way, the operating frequency is avoided from exceeding the maximum frequency that the operating voltage can support, and the chip is prevented from having operating errors and instability problems, which is conducive to improving the reliability of frequency modulation.

[0063] Frequency and voltage are related. The larger the voltage, the higher the frequency it can support. In some embodiments of the present invention, a voltage-frequency curve can be fitted based on multiple sets of preset frequencies and voltages, and the target voltage value can be determined based on the voltage-frequency curve and the target frequency value.

[0064] In some embodiments of a chip power consumption control method of the present invention, the target power consumption value is a preset maximum power consumption limit value, referring to Figure 6 , the specific frequency modulation process is: PMIC (Power Management IC) collects and updates real-time current and voltage; The Power PMU (Power Performance Monitoring Unit) queries and obtains updated real-time current and voltage as well as current frequency values ​​at a preset interval of 1 millisecond, and calculates the current power consumption value based on the real-time current and voltage; According to the difference between the updated current power consumption value and the target power consumption value, a power consumption difference ratio value is determined, and a frequency increase or decrease value is obtained by calculating the power consumption difference ratio value in combination with the current frequency value, and the current frequency value and the frequency increase or decrease value are added to obtain a calculated frequency value, and then the calculated frequency value is combined with the frequency limit range to determine the target frequency value; According to the target frequency value, determine whether to increase or decrease the frequency; When upscaling: According to the target voltage value, the output voltage of PMIC is increased through PMBUS (Power Management Bus). When the voltage is stable, FBDIV (Feedback Divider) and POSTDIV (Post Divider) are configured according to the target frequency value to gradually increase the operating frequency and complete the frequency increase. When frequency is reduced: According to the target frequency value, configure FBDIV and POSTDIV to gradually reduce the operating frequency; according to the target voltage value, reduce the output voltage of PMIC through PMBUS, and complete the frequency reduction when the voltage is stable.

[0065] The above-mentioned description of the frequency modulation process in some embodiments of the present invention is only an illustrative description to facilitate a clearer understanding of the technical solution, and does not limit the specific implementation methods of the present invention.
