[0030] The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0031] Currently, all chips require an external power supply, so it is necessary to effectively manage these power supplies. The main dynamic management includes: switching and voltage regulation. Therefore, the power management efficiency directly affects the response speed and power consumption of the chip system.

[0032] In the related art, power management mainly includes the following three aspects: First, for the power supply module of a Power Management IC (PMIC), the process of optimizing its soft start speed; for example, driving the control circuit with a faster clock and optimizing the architecture of the analog power supply to compress the turn-on time of the power supply (Buck&LDO). However, the above optimization process is often accompanied by an increase in circuit complexity, and the increase in complexity will lead to an increase in costs in various aspects such as design, manufacturing, testing, and maintenance; Second, adding an additional discharge circuit to the PMIC power supply (Buck&LDO) to quickly reduce the voltage after the power supply is turned off. Although adding a discharge circuit can greatly compress the turn-off time of the power supply, adding an additional discharge circuit is an analog design with an area overhead. To avoid excessive discharge current, the discharge time still needs to be several hundred microseconds, and the shorter the time, the larger the area of the discharge circuit; Third, by optimizing the interaction control method between the System on Chip (SOC) and the PMIC, reducing the number of communications, thereby reducing the power control management time. However, the low efficiency of the SOC multi-core software interaction control leads to frequent power state switching, which will not only increase power consumption but also may cause an additional burden on the power supply module and affect its service life.

[0033] In addition, in the SOC of mobile electronic devices (such as mobile phones), due to the uneven operation of the business load of the Central Processing Unit (CPU) subsystem software, the CPU often appears in an idle state during operation. To save the load power consumption of the CPU in the idle state, the CPU subsystem will frequently power on and off. To be able to respond to sudden interrupts in a timely manner, the power switches of each power supply path of the CPU need to be as fast as possible. Since there are sequential requirements for the power switches of each path of the CPU, this means that the time delay of the power switch will relatively affect the total turn-on and turn-off time of multiple power supplies. For example, it is necessary to first turn off the power supply of the CPU small core, and then turn off the power supply of the Static Random Access Memory (SRAM) of the CPU small core, and the power-on sequence is the opposite; in this way, the total turn-on and turn-off time is the superposition of the times of the two power supplies, and the time is often up to several tens of milliseconds or even several seconds at most.

[0034] In view of the above problems, the present disclosure proposes a power control method, device, electronic device, chip, and storage medium.

[0035] The following describes the power control method, device, electronic device, chip, and storage medium according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0036] Figure 1 It is a schematic flowchart of a power control method provided by an embodiment of the present disclosure.

[0037] It should be noted that the power control method of the present disclosure embodiments can be applied to a power control device. In some possible embodiments, the power control device can be configured in an electronic device so that the electronic device can perform a power control function. Additionally, in some possible embodiments, the power control device can also be software in the electronic device, etc.

[0038] In any one of the embodiments of the present disclosure, the power control device can be configured in a PMIC.

[0039] In any one of the embodiments of the present disclosure, the PMIC can be integrated into a chip. The chip includes a Central Processing Unit (abbreviated as CPU), Image Signal Processing (abbreviated as ISP), Application-Specific Integrated Circuit (abbreviated as ASIC), Digital Signal Processor (abbreviated as DSP), Field-Programmable Gate Array (abbreviated as FPGA), System On A Chip (abbreviated as SOC), Reduced Instruction Set Computer (abbreviated as RISC), etc., which are not listed one by one here.

[0040] As Figure 1 shown, the power control method may include the following steps:

[0041] Step 101, receive the command code value information sent by the chip.

[0042] To improve the efficiency of power management, in the embodiments of the present disclosure, the chip sends the command code value information to the PMIC through a communication interface (such as I 2 C, SPI, PMBus, etc.). The command code value information is usually composed of a series of bytes or bits, which are encoded according to a specific format and protocol. The command code value information may include the identification information of the power to be controlled and the power control commands associated with each identification information.

[0043] Step 102, parse the command code value information to obtain the power control command.

[0044] To improve the accuracy of power control, in the embodiments of the present disclosure, by parsing the command code value, the power control device can accurately identify the power to be controlled and perform corresponding operations according to the specific power control commands.

[0045] To improve the flexibility of power management, the command code value information may include power control commands for each power supply to be controlled. In the embodiments of the present disclosure, power control commands adapted to each power supply to be controlled are extracted from the command code value information.

[0046] Step 103: Use the power control command to perform on / off control on the power supply to be controlled.

[0047] Furthermore, use the power control commands adapted to each power supply to be controlled to perform on / off control on the corresponding power supply to be controlled.

[0048] Exemplarily, the control power supply is used to supply power to the chip.

[0049] The power control method of the embodiments of the present disclosure receives the command code value information sent by the chip, parses the command code value information to obtain the power control command, and then uses the power control command to perform on / off control on the power supply to be controlled. Thus, through the accurate parsing and execution of the command code value information, the accuracy and timeliness of power control are improved, power supply problems caused by misoperation or delay are avoided, at the same time, the intelligence and automation of power management are realized, manual intervention is reduced, and the operation efficiency and reliability of the chip system are improved.

[0050] To clearly illustrate how the power control command is used to perform on / off control on the power supply to be controlled for supplying power to the chip in the above embodiments, the present disclosure proposes another power control method.

[0051] Figure 2 It is a schematic flowchart of another power control method provided by the embodiments of the present disclosure.

[0052] As Figure 2 shown, the power control method may include the following steps:

[0053] Step 201: Receive the command code value information sent by the chip.

[0054] Step 202: Parse the command code value information to obtain the power control command.

[0055] Step 203: Query the voltage threshold adapted to the power control command.

[0056] In the embodiments of the present disclosure, the power control command may include a power-on command or a power-off command. The voltage threshold adapted to the power-on command is the first voltage threshold, and the voltage threshold adapted to the power-off command is the second voltage threshold. The first voltage threshold and the second voltage threshold may be equal (e.g., 035V) or not equal. The present disclosure does not make specific limitations.

[0057] Step 204: Adjust the voltage of the power supply to be controlled based on the voltage threshold.

[0058] To achieve the accuracy and timeliness of power supply control, targeted adjustment of the power supply is realized according to different power supply control commands.

[0059] As an example, when the power supply control command includes a power-on command and the power supply to be controlled is in the off state, control the power supply to be controlled to turn on, and control the power supply to be controlled to gradually rise to the first voltage threshold (e.g., 0.35V) within the first set period.

[0060] In some embodiments, the duration of the first set period is greater than the first duration threshold; that is, the power supply is slowly started up to the first voltage threshold.

[0061] As another example, when the power supply control command includes a power-off command, control the power supply to be controlled to step down to the second voltage threshold within the third set period; in some embodiments, the duration of the third set period is less than the third duration threshold; that is, quickly reduce the voltage of the power supply to be controlled to the second voltage threshold (e.g., 0.35V).

[0062] Step 205: In response to the voltage of the power supply to be controlled reaching the voltage threshold, perform a target operation on the power supply to be controlled that is adapted to the power supply control command.

[0063] To improve the accuracy of power supply control and shorten the waiting time for power supply control, as a possible implementation, when the voltage of the power supply to be controlled reaches the voltage threshold, perform the corresponding target operation on the power supply to be controlled according to the power supply control command.

[0064] As an example, when the power supply control command includes a power-on command and the voltage of the power supply to be controlled rises to the first voltage threshold, query the target operating voltage adapted to the power supply to be controlled, and based on the target operating voltage, perform a boost operation on the power supply to be controlled. For example, control the power supply to be controlled to boost to the target operating voltage within the second set period; in some embodiments, the duration of the second set period is less than the second duration threshold, that is, control the power supply to be controlled to quickly boost to the target operating voltage (e.g., 0.75V).

[0065] As another example, when the power supply control command includes a power-off command, when the voltage of the power supply to be controlled drops to the second voltage threshold, perform a power-off operation on the power supply to be controlled, that is, turn off the power supply to be controlled when the voltage of the power supply to be controlled drops to the second voltage threshold.

[0066] It should be noted that the execution processes of steps 201 to 202 can be implemented in any of the ways in the various embodiments of the present disclosure. The embodiments of the present disclosure do not make any limitations in this regard and will not be elaborated further.

[0067] The power control method according to the embodiments of the present disclosure realizes precise control of the power supply by querying the voltage threshold adapted to the power control command, adjusting the power supply voltage based on the voltage threshold, and executing the corresponding power control command, thereby improving the reliability and timeliness of power control.

[0068] To clearly illustrate how the command code value information is parsed in the above embodiments to obtain the power control command, the present disclosure proposes another power control method.

[0069] Figure 3 It is a schematic flowchart of another power control method provided by the embodiments of the present disclosure.

[0070] As Figure 3 shown, the power control method may include the following steps:

[0071] Step 301, receive the command code value information sent by the chip.

[0072] Step 302, parse the command code value information to obtain the identification information of at least one power supply to be controlled and the power control command associated with each identification information.

[0073] In order to improve the accuracy of power control, in the embodiments of the present disclosure, by parsing the command code value information, the identification information of at least one power supply to be controlled is extracted from the command code value information, and the power control instruction matching each identification information is identified.

[0074] Step 303, use the power control command to perform on-off control on the power supply to be controlled.

[0075] As an example, according to the identification information of at least one power supply to be controlled, the power supply to be controlled is determined from the power supplies supplying power to the chip, and the power control instructions corresponding to the power supplies to be controlled are used to perform on-off control on the power supply to be controlled.

[0076] It should be noted that the execution process of step 301 can be implemented in any one of the ways in the embodiments of the present disclosure. The embodiments of the present disclosure do not make any limitations in this regard and will not be elaborated further.

[0077] The power control method according to the embodiments of the present disclosure parses the command code value information to obtain the identification information of at least one power supply to be controlled and the power control command associated with each identification information, and thus uses the power control instructions corresponding to the power supplies to be controlled to perform on-off control on the power supply to be controlled, realizing precise control of the power supply.

[0078] In any embodiment of the present disclosure, as Figure 4 shown, taking the power-on of the power supply and the power control device being configured in the PMIC as an example, compared with the traditional power-on of the power supply, the power-on of the power supply in the present disclosure mainly includes the following steps:

[0079] 1. Slowly start the power supply to a sufficiently low voltage (the first voltage threshold);

[0080] 2. Control the power supply to boost to the target operating voltage again;

[0081] Furthermore, as Figure 5 shown, curve S1 represents the curve of the power-on voltage of the power supply of the present disclosure changing with time, and curve S2 represents the curve of the power-on voltage of the power supply in the traditional scheme changing with time. Among them, V1 represents the lowest voltage output by the power supply (the first voltage threshold, e.g., 0.35V), V2 represents the target operating voltage output by the power supply (e.g., 0.75V), T1 represents the time taken for the power supply of the present disclosure to slowly start to the lowest voltage output, T2 represents the time taken for the power supply of the present disclosure to boost to the target operating voltage (e.g., 0.75V) after slowly starting; T3 represents the time taken for the power supply to reach the target operating voltage after slowly starting under traditional control. Thus, compared with the traditional power-on of the power supply, the power supply control method of the present disclosure reduces the waiting time for power-on.

[0082] In any embodiment of the present disclosure, as Figure 6 shown, taking the power supply being powered off and the power supply control device being configured in the PMIC as an example, compared with the traditional power-off of the power supply, the power-off of the power supply of the present disclosure mainly includes the following steps:

[0083] 1. Control the power supply to step down to a sufficiently low voltage (the second voltage threshold);

[0084] 2. Turn off the power supply;

[0085] Furthermore, as Figure 7 shown, curve S3 represents the curve of the power-off voltage of the power supply of the present disclosure changing with time, and curve S4 represents the curve of the power-off voltage of the power supply in the traditional scheme changing with time. Among them, V1 represents a voltage lower than Vth (the set threshold voltage of the chip) (e.g., 0.2V); V2 represents the lowest voltage output by the power supply, e.g., 0.35V, V3 represents the target operating voltage output by the power supply (e.g., 0.75V); T1 represents the time taken for the power supply of the present disclosure to actively step down from voltage V3 (e.g., 0.75V) to a lower voltage V2 (e.g., 0.35V), T2 represents the time taken for the power supply of the present disclosure to drop from voltage V3 to V1 (e.g., 0.2V); T3 represents the time taken for the power supply to slowly drop from voltage V3 to V1 under traditional control. Thus, compared with the traditional power-off of the power supply, the power supply control method of the present disclosure reduces the waiting time for power-off.

[0086] To implement the above embodiments, the embodiments of the present disclosure also propose a power supply control device.

[0091] As a possible implementation, the power control command includes a power-on command, and the control module 830 is configured to, in response to the voltage of the power supply to be controlled rising to a first voltage threshold, query a target operating voltage adapted to the power supply to be controlled; based on the target operating voltage, perform a boosting operation on the power supply to be controlled.

[0093] As a possible implementation, the control module 830 is configured to control the power supply to be controlled to boost to the target operating voltage within a second set time period.

[0094] As a possible implementation, the power control command includes a power-off command, the voltage threshold includes a second voltage threshold, and the control module 830 is configured to, in response to the voltage of the power supply to be controlled dropping to the second voltage threshold, perform a power-off operation on the power supply to be controlled.

[0095] As a possible implementation, the control module 830 is configured to control the power supply to be controlled to step down to the second voltage threshold within a third set time period.
