[0030] Example 1

[0031] Figure 1A flowchart of a clock chip frequency compensation method is provided for embodiment 1 of the present invention. This embodiment is applicable to the situation where frequency compensation is performed on a clock chip. The method can be executed by a clock chip frequency compensation device. The clock chip frequency compensation device can be implemented in the form of hardware and / or software. The clock chip frequency compensation device can be configured in computer equipment such as servers.

[0032] The clock chip is a low-power real-time clock chip that needs to meet the requirements of high precision and low power consumption when in use. Since the 32K tuning fork crystal in the clock chip will be affected by temperature changes, its oscillation frequency will change with temperature, resulting in inaccurate timing of the clock chip. Therefore, it is necessary to detect the temperature changes of the clock chip. The frequency offset can be determined by the temperature changes, so as to compensate the frequency of the clock chip under different temperature conditions, so that the clock chip can continue to meet the high-precision requirements when working. In view of this, an embodiment of the present invention provides a clock chip frequency compensation scheme, which performs periodic detection on the temperature value of the clock chip to perform frequency compensation on the clock chip under different detection cycles, so that the clock chip meets the requirements of high precision and low power consumption.

[0033] Please refer to Figure 1 , the clock chip frequency compensation method provided by the embodiment of the present invention includes:

[0034] S110 , obtaining historical temperature values ​​obtained by detecting a clock chip during a historical detection period.

[0035] The historical detection cycle means that when the clock chip is working, a corresponding historical temperature value can be obtained after each detection cycle. The current historical detection cycle consists of two or more consecutive detection cycles. A detection cycle can be understood as a time period, that is, after accumulating at least two consecutive time periods of corresponding historical temperature values, it is convenient to execute subsequent steps. The advantage of doing this is to ensure the accuracy of the frequency compensation of the clock chip in subsequent steps.

[0036] Among them, in the historical detection cycle, the time period corresponding to each detection cycle is not necessarily the same. The next detection cycle needs to be determined in combination with the accuracy level of the clock chip in the subsequent steps. The advantage of this is that the clock chip can adaptively adjust the temperature detection cycle to make the timing accuracy of the clock chip more accurate.

[0037] In an optional manner, the above historical temperature values ​​are obtained by: acquiring analog temperature values ​​obtained by detecting a clock chip during a historical detection period; performing analog-to-digital conversion on the analog temperature values ​​to obtain historical temperature values.

[0038] The above-mentioned analog temperature value can be obtained by a temperature detection module integrated in the clock chip, and the temperature detection module can be implemented by a temperature sensor. Since the temperature obtained by the temperature sensor is an analog temperature value, an analog-to-digital conversion module can be integrated in the clock chip to convert the analog temperature value into a digital temperature value, thereby obtaining the historical temperature value corresponding to each historical detection cycle. In particular, the analog-to-digital converter (ADC) can be implemented.

[0039] S120: Determine a current detection cycle according to historical temperature values ​​and the accuracy level of the clock chip.

[0040] The accuracy level of a clock chip indicates the allowable deviation between the actual measured value and the standard value. The current actual value and standard value refer to the actual output frequency and the standard output frequency of the clock chip at the same temperature, that is, the nominal frequency change, in parts per million (PPM).

[0041] Generally, the accuracy requirements for clock chips vary depending on their intended use. For example, the accuracy level can be set to ±2 PPM within the 0°C to +40°C range, ±3.5 PPM within the -40°C to +0°C range, and so on. The accuracy level of a clock chip can be set at the factory or adjusted based on customer needs. The current adjustment method is customizable by the customer through software. The specific method for setting the accuracy level and the accuracy level range for a clock chip are not limited here and are subject to actual needs.

[0042] Optionally, when determining the current detection cycle based on the historical temperature value and the accuracy level of the clock chip, it is also necessary to determine the frequency compensation error corresponding to the historical temperature value. The frequency compensation error can be compared with the accuracy level of the clock chip to determine the current detection cycle.

[0043] The frequency compensation error can be obtained based on historical temperature values ​​corresponding to at least two consecutive detection cycles in the historical detection cycle. The purpose of determining the frequency compensation error is to determine the frequency compensation error during the previous detection cycle using at least two historical temperature values, thereby determining the current detection cycle based on the current frequency compensation error and the accuracy level of the clock chip, thereby ensuring the accuracy of frequency compensation during the current temperature value obtained during the current detection cycle.

[0044] S130 , obtaining a current temperature value obtained by detecting the clock chip during the current detection period.

[0045] After the current detection cycle, the current temperature value corresponding to the current detection cycle can be directly obtained. The method for obtaining the current temperature value is the same as the method for obtaining the historical temperature value, which will not be repeated here.

[0046] S140 , performing frequency compensation on the clock chip based on the current temperature value.

[0047] After determining the current detection cycle based on the historical temperature values ​​and the accuracy level of the clock chip, in the process of obtaining the current temperature value according to the current detection cycle, the frequency compensation method of the clock chip can be, after obtaining the actual output frequency corresponding to the current temperature value, further obtaining the standard output frequency corresponding to the current temperature value, and comparing the actual output frequency with the standard output frequency, so as to perform frequency compensation on the clock chip based on the standard output frequency.

[0048] The clock chip frequency compensation method provided by an embodiment of the present invention first obtains the historical temperature value obtained by detecting the clock chip during the historical detection period; then determines the current detection period based on the historical temperature value and the accuracy level of the clock chip; then obtains the current temperature value obtained by detecting the clock chip during the current detection period; and finally, performs frequency compensation on the clock chip based on the current temperature value. By using the above scheme, the detection period of the clock chip can be adaptively adjusted according to the accuracy level of the clock chip, solving the problems of high power consumption and resource waste caused by multiple level requirements of the clock chip in the same application scenario in the existing scheme. The scheme provided by the embodiment of the present invention can set the accuracy level of the clock chip according to customer needs, and has beneficial effects such as adjustable accuracy and resource saving.

[0049] Example 2

[0050] Figure 2 This is a flow chart of a clock chip frequency compensation method provided by the second embodiment of the present invention. The relationship between this embodiment and the above embodiment is the refinement of the features of the corresponding steps. Figure 2 As shown, the method includes:

[0051] S210 , obtaining historical temperature values ​​obtained by detecting a clock chip during a historical detection period.

[0052] S220: Determine a frequency compensation error according to historical temperature values.

[0053] In the measurement circuit of the clock chip, real-time frequency compensation is generally not performed on the clock chip. For example, the temperature of the clock chip is not measured every 1 second to perform frequency compensation based on the current temperature. This method is labor-intensive and the frequency error is generally within the allowable range in a short period of time. Therefore, the temperature of the clock chip is usually detected at regular intervals, and the frequency compensation error during the detection cycle is determined. The accuracy of subsequent temperature and frequency measurements is then determined based on the current frequency error to ensure the accuracy of the clock chip.

[0054] An alternative method to determine the frequency compensation error based on historical temperature values ​​can be expressed by the following expression:

[0055] σ=a*|(T1-t) 2 -(T2-t) 2 | (1)

[0056] Wherein, σ represents the frequency compensation error, α represents the first preset parameter, t represents the second preset parameter, the historical detection period includes the first detection period and the second detection period, the second detection period is the detection period before the first detection period, the first detection period is the detection period before the current detection period, T1 represents the historical temperature value detected in the second detection period, and T2 represents the historical temperature value detected in the first detection period.

[0057] The first preset parameter a represents the opening coefficient of the clock crystal, and the second preset parameter t represents the time corresponding to the peak frequency in the temperature-frequency relationship information. The temperature-frequency relationship information is pre-stored in the clock chip and includes standard output frequencies corresponding to various temperature values. The first preset parameter a and the second preset parameter t are constants, and their specific values ​​are not limited here.

[0058] S230: Obtain an adjustment step size of a frequency compensation error.

[0059] The adjustment step is generally set according to user needs, and can be set to 1 second for example. The purpose of obtaining the adjustment step of the frequency compensation error is to adjust the historical detection cycle according to the adjustment step, which helps to more accurately determine the current detection cycle in subsequent steps.

[0060] S240: Determine a current detection cycle according to the frequency compensation error, the adjustment step size, and the accuracy level.

[0061] Optionally, determining a current detection period according to a frequency compensation error, an adjustment step, and an accuracy level includes:

[0062] Determine whether the frequency compensation error exceeds the accuracy level; if it does not exceed the accuracy level, the current detection period is equal to the first detection period plus the adjustment step; if it exceeds the accuracy level, the current detection period is equal to the first detection period minus the adjustment step.

[0063] Assume the accuracy level to be Δ, and determine the size of σ and Δ obtained according to formula (1). If the frequency compensation error does not exceed the accuracy level, it indicates that the compensation accuracy of the frequency compensation error in the historical detection cycle is sufficiently accurate. The detection time of the detection cycle can be appropriately extended, and the current detection cycle is equal to the first detection cycle plus the adjustment step size. Assume that the current detection cycle is ω2 and the first detection cycle is ω1. The current detection cycle can be expressed as: ω2 = ω1 + Δ. If the frequency compensation error exceeds the accuracy level, it indicates that the compensation accuracy of the frequency compensation error in the historical detection cycle does not meet the requirements corresponding to the accuracy level. The detection time of the detection cycle can be adaptively shortened. The current detection cycle can be expressed as: ω2 = ω1 - Δ.

[0064] S250: Obtain the current temperature value obtained by detecting the clock chip during the current detection period.

[0065] S260: Obtain the actual output frequency corresponding to the current temperature value.

[0066] When frequency compensation is performed on a clock chip according to the current temperature value, it is first necessary to obtain the actual output frequency corresponding to the current temperature value. The current actual output frequency can be directly obtained by monitoring the oscillation of the clock crystal.

[0067] S270: Obtain a standard output frequency corresponding to the current temperature value from the temperature-frequency relationship information.

[0068] The temperature-frequency relationship information includes the standard output frequency corresponding to each temperature value. The temperature-frequency relationship information can be pre-stored in the clock chip, so when the current temperature value is obtained, the standard output frequency corresponding to the current temperature value can also be directly obtained.

[0069] The temperature-frequency relationship information can be stored in the clock chip in the form of a curve, where the standard output frequency corresponding to each temperature value is described as a curve, forming a temperature-frequency characteristic curve. Alternatively, the information can be stored in the form of an array, where each temperature value and its corresponding standard output frequency form an array, forming a temperature-frequency relationship table. The specific storage format of the temperature-frequency relationship information in the clock chip is not limited herein.

[0070] S280: Perform frequency compensation on the clock chip according to the actual output frequency and the standard output frequency.

[0071] According to the actual output frequency corresponding to the current temperature value and the standard output frequency, the compensation range of frequency compensation is determined, so that the output frequency of the current temperature value approaches the standard output frequency to ensure the accuracy of the clock chip during operation.

[0072] Accordingly, when executing step S210, in the historical monitoring cycle, each time a corresponding historical temperature value is obtained after a monitoring cycle, the clock chip will be frequency compensated according to the actual output frequency and the standard output frequency corresponding to the historical temperature value to ensure the accuracy of the output frequency corresponding to the temperature value obtained after each monitoring cycle.

[0073] Optionally, frequency compensation is performed on the clock chip according to the actual output frequency and the standard output frequency, including: determining a frequency error according to the actual output frequency and the standard output frequency; and when the frequency error exceeds a preset error value, frequency compensation is performed on the clock chip based on the frequency error.

[0074] The current frequency error can be set according to different user requirements, such as 1%, 3% or 5%, etc. The specific value of the frequency error is not limited here.

[0075] If the difference between the actual output frequency and the standard output frequency exceeds the frequency error value, the clock chip is compensated based on the frequency error. Frequency compensation can be performed based on the minimum, maximum, or intermediate value within the frequency error range. To ensure the accuracy of the temperature detection frequency during subsequent detection cycles based on the current temperature value, the actual output frequency is compensated to the standard output frequency. Accordingly, if the frequency error does not exceed the preset error value, the clock chip is not compensated. In other words, the actual output frequency corresponding to the current temperature value is the standard output frequency.

[0076] What you need to know is that when the clock chip is working, there is no need to constantly perform periodic compensation on the frequency of the clock chip by determining a new detection cycle. As the temperature of the clock chip gradually stabilizes with the working conditions, the corresponding frequency compensation error also tends to stabilize. When determining subsequent detection cycles based on the frequency compensation error, adjustment step, and accuracy level, the detection cycles also gradually tend to be the same, thereby ensuring smooth operation of the clock chip.

[0077] The technical solution provided by the embodiment of the present invention can be briefly described as the following process: setting the accuracy level of the clock chip, and assuming that the historical detection cycle includes a first detection cycle and a second detection cycle. When the clock chip starts working, the initial temperature value of the clock chip is obtained, and after analog-to-digital conversion, the first historical temperature value t1 is obtained; the frequency error is calculated based on the actual output frequency of t1, and the frequency compensation for the temperature of t1 is started; after the first detection cycle ω1, the second historical temperature value t2 can be obtained, and the frequency compensation for the temperature of t2 is started (the compensation method is the same as t1), wherein the current first detection cycle can be set according to the experience of the technician or set to a default cycle; the frequency compensation error is calculated based on the measured t1 and t2. It should be noted that at time points t1 and t2, the standard frequency has been compensated, so the current frequency compensation error is the frequency compensation error during the time period from t1 to t2. The second detection cycle ω2 is re-determined based on the relationship between the frequency compensation error and the accuracy level, ω2 = ω1-Δ, or ω2 = ω1+Δ. After the second detection cycle ω2, the third historical temperature value t3 is obtained, and the current frequency compensation error is calculated using the second historical temperature value t2 and the third historical temperature value t3. The current detection cycle is further re-determined based on the relationship between the current frequency compensation error and the accuracy level. After the current detection cycle, the current temperature value can be obtained. The process of determining the frequency compensation error based on the current temperature value and the previous temperature value and then determining the next detection cycle is repeated. After determining the next detection cycle, the frequency difference compensation is performed on the clock chip based on the next temperature value.

[0078] The clock chip frequency compensation solution provided in the embodiment of the present invention is that the same clock chip can cope with scenarios with various different accuracy level requirements. The detection cycle can be shortened when high accuracy is required, and the detection cycle can be extended when low accuracy is required. The accuracy level can be set according to customer needs. Compared with the existing compensation method based on fixed accuracy and fixed period, the power consumption of the compensation circuit can be reduced by more than 70%, and the implementation method is relatively simple.
