[0002] During the operation of the chip, in order to reduce the power consumption of the chip, the power can be turned off when it is not working, and then powered on again when it needs to work. Both the power-on and power-off processes require a certain amount of stabilization time. Generally, the power-off stabilization time is much longer than the power-on stabilization time. Therefore, if the power is turned on and off frequently, the power may not be completely turned off and then powered on again, that is, it is powered on at an intermediate voltage.

[0044] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0045] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0046] The power supply control method, system, storage medium and device of the present invention can determine whether the chip can be powered on directly within the voltage range of the real-time power supply of the chip, thereby realizing automatic chip power-on control, effectively protecting the stability of the chip and extending the service life of the chip.

[0047] like Figure 1 As shown, in one embodiment, the power supply power-on control method of the present invention includes the following steps:

[0048] Step S1, obtaining a first stable threshold value A, a second stable threshold value B, and a third stable threshold value C for powering off a power supply, wherein A>B>C>0.

[0049] Specifically, the first stable threshold A, the second stable threshold B and the third stable threshold C of the power-off are set by system preset or user customization, where A>B>C>0. The first stable threshold A, the second stable threshold B and the third stable threshold C are used to divide the state of the power-off. For the interval [A, B], it means that the current voltage is still in a high state and can be powered on directly. For the interval (B, C], it means that the current voltage is in an intermediate state and cannot be powered on directly. For the interval (C, 0], it means that the current voltage is in a low state and can be powered on directly.

[0050] Step S2: when a power-on request is detected after a power-off request of the chip is detected, a real-time voltage value of the chip is obtained.

[0051] Specifically, when the chip sends a power-off request and then sends a power-on request, it is necessary to determine the current voltage state and then determine whether it can be powered on directly. Therefore, when a power-off request and then a power-on request are detected, the real-time voltage value of the chip is first obtained.

[0052] In one embodiment of the present invention, obtaining the real-time voltage value of the chip includes the following steps:

[0053] 21) When a power-off request of the chip is detected, a power-off time counter is started and initialized to A.

[0054] Specifically, the present invention uses a power-off time counter to collect the real-time voltage value of the chip. Therefore, when a power-off request of the chip is detected, the power-off time counter is started at the same time, and the initial value of the power-off time counter is set to the first stable threshold A.

[0055] 22) Decrease the power-off time counter.

[0056] Specifically, since the real-time voltage value of the chip changes in a decreasing manner, the power-off time counter is made to count down. Preferably, the counting speed of the power-off time counter is consistent with the decreasing speed of the real-time voltage value of the chip.

[0057] 23) When a power-on request is detected, the real-time count value of the power-off time counter is obtained, and the real-time voltage value is set as the real-time count value.

[0058] Specifically, when the power-on request is detected, the real-time count value of the power-off time counter is read, and the real-time count value is the real-time voltage value of the chip.

[0059] Step S3: When the real-time voltage value is in the interval [A, B], control the power management module to power on the chip.

[0060] Specifically, when the real-time voltage value is in the interval [A, B], it indicates that the real-time voltage value is in a high state and can be powered on directly. Therefore, the power-on request is directly sent to the power management module so that the power management module powers on the chip. At the same time, the power-off time counter stops counting.

[0061] Step S4: When the real-time voltage value is in the interval (B, C), continue to monitor the real-time voltage value, and only when the real-time voltage value is less than C, control the power management module to power on the chip.

[0062] Specifically, when the real-time voltage value is in the interval (B, C], it indicates that the real-time voltage value is in an intermediate state and cannot be powered on directly. Therefore, it is necessary to continue waiting until the real-time voltage value is less than the third stable threshold C. When the real-time voltage value is less than the third stable threshold C, the power-on request is sent to the power management module so that the power management module powers on the chip. At the same time, the power-off time counter stops counting.

[0063] Step S5: When the real-time voltage value is in the interval (C, 0), control the power management module to power on the chip.

[0064] Specifically, when the real-time voltage value is in the interval (C, 0], it indicates that the real-time voltage value is in a low state and can be powered on directly. Therefore, the power-on request is directly sent to the power management module so that the power management module powers on the chip. At the same time, the power-off time counter stops counting.

[0065] It should be noted that the above steps S3-S5 are not executed in sequence, but are selectively executed according to the judgment conditions.

[0066] like Figure 2 As shown, in one embodiment, the power supply control system of the present invention includes a threshold acquisition module 21 , a voltage acquisition module 22 , a first control module 23 , a second control module 24 and a third control module 25 .

[0067] The threshold acquisition module 21 is used to acquire a first stable threshold A, a second stable threshold B and a third stable threshold C when the power is turned off, wherein A>B>C>0.

[0068] The voltage acquisition module 22 is used to acquire the real-time voltage value of the chip when a power-on request is detected after a power-off request of the chip is detected.

[0069] The first control module 23 is connected to the threshold acquisition module 21 and the voltage acquisition module 22, and is used to control the power management module to power on the chip when the real-time voltage value is in the interval [A, B].

[0070] The second control module 24 is connected to the threshold acquisition module 21 and the voltage acquisition module 22, and is used to continue monitoring the real-time voltage value when the real-time voltage value is in the interval (B, C], and control the power management module to power on the chip only when the real-time voltage value is less than C.

[0071] The third control module 25 is connected to the threshold acquisition module 21 and the voltage acquisition module 22, and is used to control the power management module to power on the chip when the real-time voltage value is in the interval (C, 0].

[0072] Among them, the structures and principles of the threshold acquisition module 21, the voltage acquisition module 22, the first control module 23, the second control module 24 and the third control module 25 correspond one to one with the steps in the above-mentioned power-on control method, so they are not repeated here.
