[0002] With the rapid development of electronic devices, users have higher and higher requirements for the working performance of integrated circuits, such as hashboards. In actual production, in order to ensure normal operation and operational stability, the working frequency of the hashboard often guarantees sufficient margin, but in order to obtain greater benefits, users sometimes use third-party firmware to overclock the hashboard, which will inevitably lead to a decrease in system stability and an increase in the failure rate. The traditional overclocking judgment method is mainly to obtain the frequency history log of the hashboard through the control board and make manual judgments, but this method is inefficient and has low accuracy.

[0091] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0092] Figure 1 is a flow chart of a working voltage processing method according to an exemplary embodiment. Figure 1 As shown, the working voltage processing method can be used in a processing module on a computing board or in a microprocessor such as an embedded controller. The computing board can be various computing chips and / or image processing chips, but not limited to computing chips and / or image processing chips (GPU, Graphics Processing Unit), etc., wherein the computing chip includes but is not limited to a dedicated integrated circuit (ASIC, Application Specific Integrated Circuit) chip. Figure 1 As shown, the disclosed method comprises the following steps:

[0093] In step S11, the working voltage of the load on the computing board is collected.

[0094] Here, the load on the hashboard can be part or all of the load of the hashboard, for example, the load of each chip on the hashboard, the load of some integrated circuits, or the load of some components, etc. The working voltage refers to the voltage required by the load of the entire hashboard when working, such as 18V or 20V.

[0095] The processing module of this embodiment can be installed on a computing board, such as Figure 4 As shown, this can reduce the use of connecting wires, simplify the structure of the hash board, and facilitate the collection of the working voltage of the load on the hash board.

[0096] In step S12, it is determined whether the minimum operating voltage of the load in the current time period exceeds the stored voltage, wherein the stored voltage is: the minimum operating voltage of the load in the historical time period.

[0097] The current period may be a preset period in the current load operation process. For example, during the load operation process, the processing module collects the working voltage of the load on the computing board and determines a preset time length T to divide the time. The current period is: the time period equal to T at the current moment.

[0098] The T may be 5, 10, 15 or 30 minutes.

[0099] Exemplarily, whether the minimum operating voltage in the current 10-minute period exceeds the storage voltage, or whether the minimum operating voltage in the current 30-minute period exceeds the storage voltage, etc. This embodiment does not specifically limit the preset time period, for example, it can also be 20 minutes or 40 minutes, etc.

[0100] Optionally, the processing module of this embodiment regularly collects the working voltage of the load on the computing board within a preset time period. Exemplarily, the processing module collects the working voltage of the load on the computing board within half an hour every 10 minutes, and determines whether the minimum working voltage in the current half an hour exceeds the storage voltage, or the processing module starts collecting the working voltage of the load on the computing board within half an hour according to a set time point, for example, the processing module starts collecting the working voltage of the load on the computing board within half an hour at 13:10, and determines whether the minimum working voltage in the current half an hour exceeds the storage voltage.

[0101] Here, for a hashboard that has just been put into use, the minimum operating voltage in the historical period can be 0V; for a hashboard that has been put into use for a period of time, the minimum operating voltage in the historical period can be the minimum operating voltage of the hashboard in the previous period.

[0102] Since the voltage value that can be collected by the processing module may be lower than the actual working voltage of the load, the working voltage of the load may be first reduced when the processing module collects the working voltage of the load, so that the voltage value after the reduction meets the voltage collection requirement of the processing module. It should be understood that this embodiment does not specifically limit the setting of the minimum working voltage in the historical period, and it can also be the overclocking working voltage pre-made at the factory, for example, the overclocking working voltage can be the working voltage of the overclocking state written according to statistical data or laboratory data.

[0103] In step S13, when the minimum operating voltage in the current time period exceeds the stored voltage, the minimum operating voltage in the current time period is updated to the stored voltage, wherein the stored voltage is at least used to determine whether the load on the hash board has worked in an overclocked state.

[0104] Exemplarily, during the load operation, the processing module collects the operating voltage of the load on the computing board, and determines whether the minimum operating voltage in the current period exceeds the storage voltage. For example, it is determined that the minimum operating voltage in the current 30-minute period is 4V and the storage voltage is 3V. In this way, the minimum operating voltage of 4V in the current period exceeds the storage voltage of 3V, and the minimum operating voltage of 4V in the current period is updated to the storage voltage, that is, the storage voltage becomes 4V.

[0105] Optionally, when the minimum operating voltage in the current period does not exceed the storage voltage, the storage voltage is maintained. Exemplarily, the processing module collects the operating voltage of the load on the computing board, determines that the minimum operating voltage in the current 10-minute period is 2V, and the storage voltage is 3V, so that the minimum operating voltage of 2V in the current period does not exceed the storage voltage of 3V, and the storage voltage is maintained, that is, the storage voltage remains 3V.

[0106] The stored voltage can at least be used to determine whether the load on the hash board has been operating in an overclocked state.

[0107] In the related art, after-sales service personnel use the control panel to capture logs and make manual judgments when making overclocking judgments. This is inefficient and cannot be 100% accurate. However, in order to meet work requirements and obtain more data, resources or benefits, the hashboard may often be overclocked. However, logs are easily modified or deleted, so it is impossible to accurately determine whether the hashboard is overclocked through logs.

[0108] Therefore, this embodiment determines whether the load on the hash board has worked in an overclocked state by storing the voltage, with fast identification speed and high accuracy.

[0109] Optionally, the processing module of this embodiment can directly determine whether the load on the computing board has worked in an overclocked state through the storage voltage. Specifically, when the storage voltage is greater than the minimum overclocking voltage, it is determined that the load on the computing board has worked in an overclocked state; when the storage voltage is not greater than the minimum overclocking voltage, it is determined that the load on the computing board has not worked in an overclocked state. For example, if the current storage voltage is 4V and the minimum overclocking voltage is 3.5V, it is determined that the load on the computing board has worked in an overclocked state, or if the current storage voltage is 3V and the minimum overclocking voltage is 3.5V, it is determined that the load on the computing board has not worked in an overclocked state.

[0110] In other embodiments, the original voltage of the storage voltage may be 0V, so that the minimum operating voltage of the hash board that has just been put into use in the first period can be successfully recorded as the storage voltage.

[0111] Optionally, in this embodiment, the storage voltage of the processing module can be obtained by the host computer, and then the host computer determines whether the load on the computing board has worked in an overclocked state through the storage voltage.

[0112] like Figure 4 , the host computer is connected to a signal output pin of the processing module, and the host computer obtains the current storage voltage of the processing module. When the storage voltage is greater than the minimum overclocking voltage, it is determined that the load on the hashboard has worked in an overclocked state. When the storage voltage is not greater than the minimum overclocking voltage, it is determined that the load on the hashboard has not worked in an overclocked state. For example, if the current storage voltage obtained by the host computer is a first voltage, and the minimum overclocking voltage stored inside the host computer is a second voltage greater than the first voltage, it is determined that the load on the hashboard has worked in an overclocked state. The minimum overclocking voltage here is the minimum voltage stored by the host computer that the load on the hashboard has worked in an overclocked state.

[0113] In some embodiments, after determining that the load on the hash board has worked in an overclocked state, information such as the storage voltage, overclocking time period or time of the current overclocked state is also recorded to facilitate the judgment of the faulty hash board and quickly determine the cause of the failure of the hash board.

[0114] In other embodiments, the storage voltage of this embodiment can also be used to determine whether the load on the hash board is in a normal working state, or whether a fault occurs.

[0115] In the above embodiment, in view of the feature that overclocking requires pressure, the working voltage of the load is obtained in real time by the processing module on the hash board, and the minimum working voltage of the load in the current period is compared with the storage voltage to determine whether the load on the hash board has worked in an overclocked state. That is, this embodiment solidifies the above method into the hash board. As long as the user performs pressure overclocking, it will be recognized and recorded by the processing module on the hash board. The recognition speed is fast and the accuracy is high. At the same time, it is convenient for the after-sales department to judge the faulty hash board and quickly determine the cause of the failure of the hash board.

[0116] In one embodiment, all operating voltages collected at a preset frequency in the current period are recorded, and when it is necessary to determine the minimum operating voltage in the current period, all recorded operating voltages are traversed to determine the minimum operating voltage.

[0117] In another embodiment, Figure 2 As shown, the working voltage processing method may further include:

[0118] In step S21, within a current period, the current operating voltage of the load collected at a preset frequency is compared with the recorded voltage.

[0119] Here, the recorded voltage may be a voltage preset at the factory, which is used to determine the minimum operating voltage of the load in the current period, for example, the recorded voltage is 5V, or it may be an operating voltage written in statistical data or laboratory data.

[0120] Exemplarily, during the current half-hour period, the processing module collects the current operating voltage of the load at a frequency of 20,000 Hz, and compares the operating voltage of the load collected each time with the recorded voltage. For example, the recorded voltage may be 5V, and the processing module compares the operating voltage with 5V each time it collects it.

[0121] The present embodiment does not specifically limit the preset frequency. Preferably, the preset frequency is greater than 10000 Hz, so that the voltage collection in the overclocking state will not be missed due to too few collection times, thereby ensuring real-time monitoring of the working state of the load on the hash board and improving the accuracy of overclocking identification.

[0122] In step S22, when the current operating voltage is less than the recorded voltage, the current operating voltage is updated to the recorded voltage.

[0123] In step S23, when the current operating voltage is greater than the recording voltage, the current recording voltage is maintained.

[0124] In step S24, at the end of the current period, the recorded voltage is determined as the minimum operating voltage in the current period.

[0125] For details, see Figure 3 , the recorded voltage is A, the current working voltage is B, and the storage voltage is C. The processing module collects the working voltage of the load on the computing board at a preset frequency. In the current half-hour period, the collected current working voltage B of the load is compared with the recorded voltage A. If the current working voltage B is less than the recorded voltage A, the current working voltage B is updated to the recorded voltage A.

[0126] After completing the size determination between the current working voltage and the recorded voltage, it is determined whether the current round of working voltage collection has reached a preset time, such as half an hour.

[0127] If the collection of the working voltage in this round has reached the preset time length, the current recorded voltage A is determined as the minimum working voltage in the current period.

[0128] If the current round of working voltage collection does not reach the preset time length, the current working voltage B continues to be collected and compared with the recorded voltage A until the current period ends.

[0129] Furthermore, the processing module determines whether the minimum operating voltage of the load in the current period exceeds the stored voltage C. When the minimum operating voltage in the current period exceeds the stored voltage C, the minimum operating voltage of the current period is updated to the stored voltage C. If the minimum operating voltage in the current period does not exceed the stored voltage C, the current stored voltage C is maintained, and the current operating voltage B of the next period is continuously collected to determine whether the minimum operating voltage of the next period exceeds the stored voltage C. Finally, it can be determined based on the stored voltage C whether the load has worked in an overclocked state.

[0130] Using this method, only one recorded voltage needs to be stored in a time period, which is equivalent to storing all collected working voltages, reducing the consumption of storage resources; and every time a latest working voltage is collected, it will be compared with the recorded voltage, so that at the end of the current time period, the recorded voltage can be directly determined as the minimum working voltage of the current time period, thereby having the characteristic of fast minimum working voltage determination rate.

[0131] In some embodiments, the working voltage processing method may further include: when the minimum working voltage in the current period exceeds the storage voltage, outputting a power-off signal, wherein the power-off signal is used to control the power supply module to stop supplying power to the load.

[0132] See also Figure 4 The processing module is also connected to the power supply module that supplies power to the load on the hash board. When the processing module determines that the minimum operating voltage in the current period exceeds the storage voltage, it can be determined that the load has worked in an overclocked state. In order to prevent the hash board from overclocking, the processing module will output a power-off signal to control the power supply module to stop supplying power to the load.

[0133] For example, if the minimum operating voltage in the current period is 4.5V and the storage voltage is 4V, the processing module outputs a power-off signal to control the power supply module to stop supplying power to the load, thereby reducing the phenomenon of overclocking of the computing board. That is, this embodiment can achieve forced power-off after a random period of time during overclocking, thereby reducing the degree of damage to the computing board caused by overclocking of the computing board.

[0134] Optionally, the processing module of this embodiment can also store a minimum overclocking voltage. When the current stored voltage is greater than the minimum overclocking voltage, it is determined that the load on the hash board has worked in an overclocked state, and a power-off signal is output to control the power supply module to stop supplying power to the load.

[0135] For example, if the current storage voltage is 4.5V and the minimum overclocking voltage is 3.5V, the processing module determines that the load on the hash board has worked in an overclocked state and outputs a power-off signal to control the power supply module to stop supplying power to the load, thereby reducing the duration of the hash board's overclocking operation and reducing the degree of damage to the hash board caused by the hash board's overclocking operation.

[0136] In some embodiments, the power-off signal may include: a group of signals, which will control the power supply to cut off the power supply of different loads on the computing board in sequence according to the power-off protection timing of the computing board, thereby reducing the software and hardware damage caused by the computing board being cut off from all power supplies at once.

[0137] Optional, such as Figure 4 The host computer is connected to the processing module and can also be connected to the power supply module. In this way, the current storage voltage of the processing module can be obtained through the host computer. When the storage voltage is greater than the minimum overclocking voltage, it is determined that the load on the hash board has worked in an overclocked state, and a power-off signal is output to the power supply module to control the power supply module to stop supplying power to the load, thereby reducing the phenomenon of overclocking of the hash board.

[0138] Of course, the storage voltage can only be used to locate the fault of the hash board in the future. In this case, the host computer does not need to output a power-off signal when the storage voltage is greater than the overclocking working voltage. In this case, the output of the power-off signal is reduced, which causes the hash board to stop working, resulting in poor user satisfaction or forced cessation of the hash board's work.

[0139] In some embodiments, the processing module may have a first mode and a second mode.

[0140] Specifically, in the first mode, the power-off signal is generated when the processing module determines that the minimum operating voltage in the current period exceeds the storage voltage. In the second mode, the power-off signal is not generated when the processing module determines that the minimum operating voltage in the current period exceeds the storage voltage.

[0141] In this way, the use mode of the processing module can be selected according to actual needs. For example, a sudden power failure may cause data loss, etc., resulting in unnecessary losses. At this time, based on user input, the second mode is selected, and the processing module only needs to record the storage voltage.

[0142] If the hashboard fails, data can be provided to maintenance personnel. For example, if you want to use the hashboard normally and stably, in order not to damage the equipment, or the hashboard will not lose data after power failure, you can continue to work before power failure after power is supplied. In this way, the working mode of the processing module is set to the second mode. When the minimum working voltage in the current period exceeds the storage voltage, a power-off signal is generated to protect the hashboard, increase its lifespan, and reduce software and hardware failures of the hashboard.

[0143] In one embodiment, Figure 4 As shown, at least one pin of the processing module is connected to the power supply bus of the load on the computing board; wherein the power supply bus supplies power to the load, and the power supply voltage of the power supply bus is the working voltage of the load.

[0144] For example, a signal receiving pin of the processing module is connected to the power supply bus of the load on the hash board to collect the power supply voltage of the power supply bus. A signal output pin of the processing module is also connected to the power supply bus of the load on the hash board. When the processing module generates a power-off signal, the power supply bus can be disconnected from the load to stop supplying power to the load. In this way, there is no need to connect the processing module to the power supply module, which is convenient for collecting voltage and controlling power supply. Since the use of connecting wires is reduced, the structure of the overall hash board is also simplified.

[0145] In some embodiments, the processing module may include: an ADC, a programmable unit, and a memory.

[0146] Exemplarily, the analog pin of the ADC is connected to the power supply bus; the output pin of the programmable unit is connected to the switch on the power supply bus, which is used to disconnect or connect the connection between the load and the power supply bus. The data receiving pin of the programmable unit is connected to the memory, which is used to obtain the storage voltage recorded in the memory.

[0147] As another example, the ADC is used to convert the analog signal of the load working voltage obtained into a digital signal and output it to the programmable unit, the memory is used for the processing module to record the storage voltage, and the programmable unit can obtain the storage voltage from the memory and compare it with the minimum working voltage. Here, the memory can be a Flash memory, or a data storage device such as a ROM or a random access memory (RAM).

[0148] For example, see Figure 6 , the processing module can be a PIC chip, and the PIC chip includes an ADC, a programmable unit and a memory. For example, the analog pin RC2 of the PIC chip is connected to the power supply bus for collecting the voltage of the power supply bus, and the signal output pin RA2 of the PIC chip is connected to the switch on the power supply bus for controlling the disconnection or connection of the switch on the power supply bus, thereby controlling the power supply bus to supply power to the load. The programmable unit inside the PIC chip determines whether the minimum operating voltage of the load in the current period exceeds the storage voltage in the memory. When the minimum operating voltage in the current period exceeds the storage voltage, the minimum operating voltage of the current period is updated to the storage voltage, and then it can be determined whether the load on the computing board has worked in an overclocked state according to the storage voltage.

[0149] In the above embodiment, in terms of hardware: the voltage of the power supply bus is divided and then given to the analog pin of the processing module. Through the continuous acquisition interrupt function of the analog pin of the processing module, it can be ensured that the processing module performs the working voltage acquisition work of the load at a preset frequency, and compares the minimum working voltage in the current period with the internally stored storage voltage. When the minimum working voltage exceeds the storage voltage, the minimum working voltage is updated to the storage voltage, that is, updated to the memory for storage, so that the storage voltage is recorded in the internal memory, and whether the load is overclocked is determined according to the storage voltage. In this way, the overclocking identification structure and process are simplified, the overclocking identification speed is fast, and the accuracy is high, thereby avoiding overclocking of the computing board and ensuring normal operation.

[0150] At the same time, the storage voltage recorded in the internal memory can also be used for after-sales verification. For example, after-sales personnel can use special fixtures to obtain the voltage value stored in the internal memory of the processing module from the hashboard, and compare it with the minimum overclocking voltage to determine whether the hashboard uses special firmware overclocking.

[0151] In one embodiment, a voltage divider circuit is provided between the processing module and the power supply bus; the voltage divider circuit is used to divide the supply voltage of the power supply bus and input the voltage into the processing module.

[0152] Since the normal operating voltage of the load on the computing board is between 18V and 20V, the processing module cannot directly collect such a high voltage value. Therefore, this embodiment uses a voltage divider circuit to reduce the actual working voltage according to the voltage divider ratio. For example, the working voltage collected by the processing module can be 3V, or less than 3V, etc., to meet the collection requirements of the processing module; at the same time, the voltage divider circuit can also be used as a protection circuit to prevent high voltage from impacting the processing module.

[0153] Alternatively, see Figure 5 The voltage divider circuit of this embodiment may include: a first resistor R29 , a second resistor R32 , a third resistor R28 and a filtering unit 20 .

[0154] Specifically, the first end of the first resistor R29 is connected to the power supply bus (VDD_18V0 end) of the load on the computing board, and the second end of the first resistor R29 is connected to the first end of the second resistor R32; the second end of the second resistor R32 is respectively connected to the first end of the third resistor R28 and the input end of the filter unit 20; the second end of the third resistor R28 and the ground end of the filter unit 20 are both grounded; the output end of the filter unit 20 is connected to the processing module (AN6 pin).

[0155] In addition, the voltage divider circuit also includes a VDD_IN terminal, so that the voltage divider circuit can also be applied to other integrated circuits, such as an integrated circuit with an operating voltage of 20V, making the voltage divider circuit of this embodiment more practical and adaptable to a variety of integrated circuits, so that the processing module of this embodiment can identify the overclocking status of a variety of integrated circuits.

[0156] The above-mentioned voltage divider circuit forms a certain voltage divider ratio through the first resistor R29, the second resistor R32, and the third resistor R28 to achieve voltage division of the working voltage of the load. For example, the voltage divider ratio is 1:6, so that the 18V voltage is reduced to 3V for collection by the processing module. The filtering unit 20 filters the voltage signal to reduce interference with the collected voltage signal.

[0157] Optionally, the filter unit 20 of this embodiment may include: a fourth resistor R25, a first capacitor C22 and a second capacitor C21. Figure 5 As shown, the first end of the fourth resistor and the first end of the first capacitor are both connected to the second end of the third resistor R28; the second end of the fourth resistor and the first end of the second capacitor are both connected to the analog pin of the processing module; the second end of the first capacitor and the second end of the second capacitor are both grounded.

[0158] The above-mentioned filtering unit can realize low-pass filtering, filter out high-frequency signals, reduce interference with the collected working voltage, and make the collected voltage more stable and accurate. Preferably, the filtering frequency of the low-pass filter is greater than 300KHZ, which meets the collection requirements of the processing module and reduces interference with the collected working voltage.

[0159] In one embodiment, the outer surface of the processing module has an anti-counterfeiting protective layer, wherein the anti-counterfeiting protective layer is used to determine the authenticity of the storage voltage recorded in the memory at least through the anti-counterfeiting protective layer.

[0160] This embodiment implements cracking from the hardware structure, and realizes overclocking by connecting the processing module to the power supply bus of the load of the computing board. In this way, the method disclosed in the present invention can work normally in various situations. In order to prevent users from tampering with the processing module program, an anti-counterfeiting protection layer is used.

[0161] Specifically, the anti-counterfeiting protection layer can prevent users from cracking the method disclosed in the present invention, thereby protecting the processing module. The anti-counterfeiting protection layer can timely detect whether the user has dismantled the processing module or modified the data stored in the processing module, thereby ensuring the authenticity of the storage voltage recorded in the memory of the processing module, thereby ensuring the accuracy of overclocking identification.

[0162] Optionally, the anti-counterfeiting protection layer of this embodiment may include: thermal conductive glue.

[0163] Specifically, in this embodiment, the thermal conductive adhesive can be applied to the processing module and the connection between the processing module and the computing board to protect the processing module. The degree of damage to the thermal conductive adhesive can be used to determine whether the user has removed the processing module or modified the data stored in the processing module, thereby ensuring the authenticity of the storage voltage recorded in the memory of the processing module and reducing the anti-counterfeiting cost.

[0164] The thermal conductive adhesive is also used to dissipate heat from the processing module, that is, the thermal conductive adhesive of this embodiment can be used as both an anti-counterfeiting protective layer and a heat dissipation layer of the processing module, simplifying the outer layer structure of the processing module and achieving the effect of killing two birds with one stone. It should be understood that this embodiment does not limit the material of the thermal conductive adhesive, which can be at least one or more of thermal conductive silicone grease, thermal conductive silica gel, and thermal conductive mud.

[0165] Optionally, the anti-counterfeiting protective layer may further include: anti-counterfeiting paint. In this embodiment, the anti-counterfeiting paint may be applied to the processing module and the connection between the processing module and the computing board to protect the processing module. The degree of damage to the anti-counterfeiting paint is used to determine whether the user has dismantled the processing module or modified the data stored inside the processing module, thereby ensuring the authenticity of the storage voltage recorded in the memory of the processing module, and at the same time reducing the anti-counterfeiting cost.

[0166] In order to prevent users from tampering with the processing module program and ensure the authenticity of the storage voltage recorded in the memory of the processing module, this embodiment uses thermal conductive glue or anti-counterfeiting paint as an anti-counterfeiting protective layer to protect the processing module, which not only reduces the anti-counterfeiting cost, but also can promptly detect whether the user has dismantled the processing module or modified the data stored in the processing module, thereby ensuring the authenticity of the storage voltage recorded in the memory of the processing module, and further ensuring the accuracy of overclocking identification.

[0167] The present disclosure is applied to a processing module on a hash board, and the working voltage of the load on the hash board is directly obtained through the processing module, and overclocking identification is performed through the obtained voltage, and the identification speed is fast; wherein, when the minimum working voltage of the load in the current period exceeds the storage voltage, the minimum working voltage of the current period is updated to the storage voltage, and whether the load on the hash board has worked in an overclocked state is determined according to the storage voltage, so that overclocking identification is achieved through the working voltage of the load on the hash board, which not only has a fast identification speed but also has higher accuracy, thereby avoiding overclocking of the hash board as much as possible; at the same time, an anti-counterfeiting protective layer is set on the processing module by using thermal conductive glue or anti-counterfeiting paint, which not only reduces the anti-counterfeiting cost, but also can timely discover whether the user removes the processing module or modifies the data stored in the processing module, thereby ensuring the authenticity of the storage voltage recorded in the memory of the processing module, thereby ensuring the accuracy of overclocking identification.
