The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0057] With the continuous evolution of integrated circuit technology, the integration and computing power of chips have been significantly improved. However, high-frequency operation and high-density integration lead to a sharp increase in power consumption, especially in high-performance processors, programmable logic devices, and complex system-on-chips.

[0058] In related technologies, an adaptive voltage scaling (AVS) technology is used to communicate with a power management IC (PMIC) to realize voltage feedback adjustment.

[0070] The embodiments disclosed herein are applied to scenarios where the master device or master device processor performs voltage regulation, and are adapted to diverse hardware resources to realize communication and interaction between the master device or master device processor and the slave device.

[0071] Figure 1 This is a flowchart illustrating a power consumption regulation method provided in an embodiment of the present disclosure, as shown below. Figure 1 As shown, the power consumption regulation method includes steps 101-103.

[0072] Step 101: Establish a communication connection with the slave device based on the Serial Peripheral Interface (SPI) bus; wherein the SPI bus is obtained by reusing existing target physical pins, and the target physical pins have the function of data interaction with the slave device.

[0073] The Serial Peripheral Interface (SPI) bus is a high-speed, full-duplex, synchronous serial communication bus. The SPI bus serves as a communication bridge between master and slave devices, allowing the master device to establish a communication connection with the slave device.

[0074] In this embodiment, the master device sends control commands to the slave device. The master device includes, but is not limited to, a management subsystem, a control processor, and an external embedded controller. The slave device executes or responds to the control commands sent by the master device, i.e., it is controlled by the master device. For example, when the slave device is a power management IC (PMIC) connected to the master device via an SPI bus, it uses the control commands sent by the master device to achieve power consumption regulation or perform other functions (such as data acquisition, processing, etc.). It should be noted that the slave device can be any type of device besides a PMIC, such as a sensor acquisition device, a monitoring device, or other slave devices performing other functions; the specific type is not limited.

[0075] In this embodiment, the signal transmission, data sending, and data receiving functions of the SPI bus are determined by reusing existing target physical pins in the master device, thereby realizing data interaction between the master and slave devices. These target physical pins include, but are not limited to, the SCLK pin, MOSI pin, and MISO pin. It should be noted that the above target physical pins are merely illustrative and are not intended to be specific.

[0076] By reusing the existing target physical pins of the master device to build the SPI bus, reliable communication between master and slave devices is achieved without the need for additional hardware resources. This reduces the complexity and cost of hardware design. Only lightweight protocol parsing logic needs to be integrated in the slave device, eliminating the need for complex processing logic. This saves area and power consumption, improves resource utilization, and enhances system adaptability.

[0077] Step 102: Send a control command to the slave device based on the SPI bus, so that the slave device generates power consumption information corresponding to the control command.

[0078] The master device sends control commands to the slave device via the SPI bus. These control commands are encapsulated in AVS format as SPI data frames. The control commands are used to indicate that the master device instructs the slave device to provide power consumption information. The slave device generates corresponding power consumption information (such as the slave device's current, voltage, temperature, etc.) based on the received data frames.

[0079] In some embodiments, the slave device receives network matrix operation requests sent by the master device via the SPI bus and returns the results to the master device, which is part of the master device's functional extension.

[0080] For example, the master device sends a control command to the slave device, and the slave device's PMIC generates corresponding power consumption information based on the control command. The control command can carry target power consumption information, such as "target voltage is 1.0V, adjustment response time ≤ 10μs," or it can carry power consumption feedback indication information. The power consumption information fed back by the slave device could be, for example, "current voltage is 0.8V, response time is 20μs." It should be noted that the above is only an example and is not intended to limit the specific implementation.

[0081] The master device sends control commands via the SPI bus and prompts the slave device to generate corresponding power consumption information. With the help of the efficient communication characteristics of the SPI bus, the voltage control requirements of the master device are accurately transmitted to the slave device, meeting the power supply requirements of the master device under different operating conditions and realizing fine control of power consumption.

[0082] Step 103: In response to the power consumption information received via the SPI bus, adjust the power consumption based on the power consumption information.

[0083] The master device receives power consumption information from the slave device via the SPI bus. The master device adjusts the power consumption according to the power consumption information to meet the power consumption requirements of the master device under different loads.

[0084] For example, when the master device receives power consumption information from the slave device via the SPI bus: "Current voltage is 0.8V, response time is 20μs," and the master device's required values ​​are: "Target voltage is 1.0V, adjustment response time ≤ 10μs," the master device adjusts the power consumption based on the slave device's power consumption information: "Increase the voltage from the current voltage of 0.8V to 1.0V at a rate of 0.02V / μs, and adjust the response time from 20μs to ≤ 10μs." It should be noted that the above is only an example and is not intended to limit the specific implementation.

[0085] As one implementation of this disclosure, when the master device determines that power consumption adjustment is required based on the power consumption information received from the slave device, the master device controls the slave device to perform power consumption adjustment (such as adjusting voltage, frequency, fan, etc.).

[0086] In another implementation of this disclosure, when the master device determines that power consumption needs to be adjusted based on the power consumption information received from the slave device, the master device sends a power consumption adjustment command to the slave device, and the slave device performs the power consumption adjustment.

[0087] In summary, the power consumption regulation method provided in this disclosure includes: establishing a communication connection with a slave device based on an SPI bus, wherein the SPI bus is obtained by reusing existing target physical pins, the target physical pins having the function of data interaction with the slave device; sending control commands to the slave device based on the SPI bus to enable the slave device to generate power consumption information corresponding to the control commands; adjusting power consumption based on the power consumption information received through the SPI bus; and realizing data interaction with the slave device by reusing existing target physical pins based on the SPI bus, thereby improving compatibility with different types of PMICs and achieving fine-grained power consumption regulation.

[0088] Figure 2 This is a schematic diagram of a hardware topology for voltage regulation provided in an embodiment of this disclosure. The SPI bus includes synchronization pins (such as the SCLK pin), output pins (such as the MOSI pin), and input pins (such as the MISO pin). The synchronization pin is the target physical pin for transmitting the synchronization clock signal in the SPI bus. The master device controls the generation and output of the clock signal to ensure that the actions of the master device sending data and the slave device receiving data are synchronized in time, avoiding data transmission errors due to timing deviations. The output pin is the target physical pin for transmitting data from the master device to the slave device. It is responsible for carrying output signals such as control commands generated by the master device, establishing a unidirectional data channel from the master device to the slave device, and ensuring that the information from the master device is transmitted to the slave device in a directional manner. The input pin is the target physical pin for the slave device to feed back data to the master device, establishing a feedback data channel from the slave device to the master device, enabling the master device to obtain information such as the power consumption information of the slave device. It should be noted that the three target physical pins included in the SPI bus are only illustrative examples, and the specific number is not limited.

[0089] By reusing target physical pins such as synchronization pins, output pins, and input pins, data transmission and timing synchronization functions can be performed at different communication stages or for different slave devices without adding additional hardware pins. This achieves efficient utilization of pin resources, reduces the number of pins used in hardware design, and lowers circuit complexity and hardware costs. When the master device needs to communicate with multiple slave devices, or when the slave devices themselves have limited pin resources, reusing target physical pins can meet the basic requirements of SPI bus communication while avoiding pin resource shortages and ensuring the integrity of communication functions.

[0090] Figure 3 A flowchart illustrating a power consumption regulation method provided in an embodiment of this disclosure is further shown. Based on Figure 1 The illustrated embodiments and Figure 2 The diagram shown is as follows. Figure 3 This may include the following steps:

[0091] Step 201: Establish a communication connection with the slave device through the synchronization pin of the SPI bus.

[0092] In this embodiment of the disclosure, a communication connection is established between the master device and the slave device through a synchronization pin, and signal transmission between the master device and the slave device is realized through the communication connection between the master device and the slave device.

[0093] In some embodiments, the SPI bus is pre-initialized, and the number of bits transmitted per transmission (including binary bits such as 8 bits, 16 bits, etc.), transmission mode, etc. are configured to ensure that the master device and the slave device maintain strict timing synchronization during data interaction, reduce data transmission errors caused by timing deviations, and the communication connection method is simple and direct, without the need for complex hardware configuration.

[0094] Step 202: Encapsulate the preset adaptive voltage regulation format information to obtain the control command, and send the control command to the slave device through the output pin of the SPI bus.

[0095] To establish a communication connection with the slave device PMIC, the master device first calls its own controller to encapsulate the preset adaptive voltage regulation format information and generate control commands. However, the preset adaptive voltage regulation format information cannot be directly recognized by the slave device PMIC, so it needs to be encapsulated to conform to the PMIC's parsing rules.

[0096] After encapsulating the preset adaptive voltage regulation format information, the control command is obtained. The master device transmits the control command to the slave device PMIC through the output pin of the SPI bus. By utilizing the transmission characteristics of the output pin, the risk of data transmission errors is reduced and the directionality of information transmission is improved, thereby ensuring the reliability of the control command transmission from the master device to the slave device.

[0097] Step 203: Based on the input pin, receive the power consumption information, parse the power consumption information according to the preset adaptive voltage adjustment format information, obtain the power consumption parameters, and adjust the power consumption according to the power consumption parameters.

[0098] In some embodiments, the power consumption parameters include at least one of voltage, current, and temperature.

[0099] The slave device PMIC will transmit the generated power consumption information to the master device through the input pin of the SPI bus according to the preset adaptive voltage regulation format. After receiving the power consumption information, the master device will parse the power consumption information according to the preset adaptive voltage regulation format.

[0100] Through standardized parsing methods, the master device can extract power consumption parameters from power consumption information, avoiding control errors caused by information extraction bias. Based on the power consumption parameters, the master device can perform operations such as frequency reduction and fan adjustment to further ensure the safe operation of the equipment. Simultaneously, the master device adjusts the output power consumption value based on the power consumption parameters. For example, when the temperature is detected to be too high in the power consumption parameters, the master device reduces the voltage to reduce equipment heat generation; when the current is detected to be increasing in the power consumption parameters, the master device increases the voltage to ensure stable performance. It should be noted that the above examples are merely illustrative and are not intended to limit the specific implementation.

[0101] Through the power consumption regulation mechanism, problems such as power redundancy and equipment overheating caused by excessive power consumption can be avoided, and the performance degradation or instability of the main equipment caused by insufficient voltage can be prevented, thereby achieving dual optimization of system energy efficiency and operational reliability.

[0102] In some embodiments, the SPI bus supports full-duplex communication. The master device can send newly generated control commands to the slave device PMIC based on the output pin. At the same time, the master device can also receive feedback information such as power consumption information transmitted by the slave device PMIC based on the input pin. The full-duplex communication mode enables bidirectional synchronous information exchange between the master and slave devices, without waiting for one side to complete sending before the other side receives, thus improving communication efficiency.

[0103] It should be noted that there is no restriction on the execution order between steps 202 and 203.

[0104] Figure 4 A flowchart illustrating a power consumption regulation method provided in an embodiment of this disclosure is further shown. Based on Figure 3 The embodiment shown, Figure 4 This may include the following steps:

[0105] Step 301: Establish a communication connection with the slave device through the synchronization pin of the SPI bus.

[0106] Step 302: Encapsulate the preset adaptive voltage regulation format information to obtain the control command, and send the control command to the slave device through the output pin of the SPI bus.

[0107] Step 303: Based on the input pin, receive the power consumption information, parse the power consumption information according to the preset adaptive voltage adjustment format information, obtain the power consumption parameters, and adjust the power consumption according to the power consumption parameters.

[0108] For explanations of steps 301-303, please refer to the above. Figure 3 The detailed description of the relevant steps will not be repeated here.

[0109] Step 304: The newly generated control command after adjusting the power consumption is sent to the slave device via the SPI bus, so that the slave device can update or regenerate the power consumption information according to the newly generated control command.

[0110] After acquiring power consumption parameters and completing power consumption adjustment, the master device sends the newly generated control command to the slave device to provide feedback and adjustment for possible instability of the master device. When the newly generated control command does not match the current power consumption requirements, the slave device will update the original power consumption information or regenerate a new command to ensure that the power consumption information is consistent with the requirements of the master device and that the voltage requirements executed by the slave device meet the current operating conditions of the master device.

[0111] To facilitate better understanding, an example is given below. The master device sends a control command of "target voltage 1.0V, adjustment rate 0.02V / μs". The slave device generates corresponding power consumption information and executes it. When the master device detects a high voltage through power consumption parameters (e.g., actual power consumption is lower than expected), the newly generated control command becomes "target voltage 0.95V, adjustment rate maintained at 0.02V / μs". In this case, the slave device only needs to update the "target voltage 1.0V" in the original power consumption information, keeping parameters such as the adjustment rate unchanged, to obtain the updated power consumption information. However, if the master device experiences a drastic change in operating conditions (e.g., switching instantly from low load to high load), the newly generated control command not only includes "target voltage increased from 0.8V to 1.2V" but also adds parameters that differ significantly from the original power consumption information, such as "current increased to 2A, adjustment response time compressed to 5μs". Since the power consumption parameters in the original power consumption information have all changed, the slave device cannot adapt by updating and must regenerate the power consumption information according to the new control command. It should be noted that the above is only an illustrative example and is not intended to limit the specific implementation.

[0112] As one implementation of this disclosure, in the design of a field-programmable gate array (FPGA), at least one slave device (PMIC) is uniformly controlled based on the SPI bus, and a programmable voltage regulation strategy is achieved by adjusting different types of PMICs.

[0113] As another implementation of the present disclosure, in a heterogeneous multi-core processing platform, different types of PMICs are controlled based on multiple SPI buses to achieve partitioned power consumption optimization and reduce resource waste.

[0114] Please continue reading. Figure 2The diagram illustrates how the master device synchronizes its transmission timing with slave device 1 via the synchronization pin in the SPI bus. The master device sends control commands to slave device 1 via the output pin and receives power consumption information output by slave device 1 via the input pin. Furthermore, the SPI bus is compatible with different types of slave devices. By connecting at least one external slave device 2, the master device can control slave device 2 according to its different functions. The newly generated control command after adjusting the power consumption is sent to slave device 1, and the power consumption information generated by slave device 1 is fed back to the master device.
