Description

Power supply method, device, electronic equipment and readable storage medium
Technical Field

Background
The power consumption of the mobile phone is one of factors affecting the comprehensive use time of the mobile phone, and the power consumption of a double rate synchronous dynamic random Access Memory (DDR SDRAM) is used as one of the power consumption of the mobile phone. The dynamic voltage frequency adjustment DVFSC mechanism is a power saving mechanism corresponding to the DDR. Referring to fig. 1, only switch K2 is turned on when the DDR is operating at a high frequency, VDD2H supplies power to the logic unit, and only switch K1 is turned on when the DDR is operating at a low frequency, VDD2L supplies power to the logic unit, and power consumption is saved by providing different power supply voltages to the logic unit.
Referring to fig. 1, a parasitic diode P1 exists in the switch K1, a parasitic diode P2 exists in the switch K2, and when the DDR operates at a high frequency, a voltage difference exists between VDD2H and VDD2L to cause the parasitic diode P1 to be turned on, and VDD2H leaks to VDD2L to cause VDD2L to enter a protection state. When the DDR is switched to low frequency, the switch K1 is conducted, and the VDD2L cannot timely exit the protection state, so that the DDR works abnormally. Based on this, a pull-down resistor to ground can be added at the VDD2L output to drain the leakage current to VDD2L through the pull-down resistor to avoid VDD2L from entering the protected state, however, adding the pull-down resistor increases the cost and layout area, and the presence of the pull-down resistor increases the power consumption.

All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the objects identified by "first," "second," etc. are generally of a type not limited to the number of objects, for example, the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
Before describing the power supply method provided by the embodiment of the application, an electronic device to which the power supply method is applied is first described.
Referring to fig. 2, the electronic device 20 may include a processor 210, a memory module 220, and a power management module 230. The processor 210 is connected to the memory module 220 and the power management module 230, respectively, and the memory module 220 and the power management module 230 are connected.
The memory module 220 may be a DDR SDRAM, and the memory module 220 includes a first switch 221, a second switch 222, and a logic unit 223, the first switch 221 is connected to the power management module 230 and the logic unit 223, the second switch 222 is connected to the power management module 230 and the logic unit 223, respectively, and the first switch 221 and the second switch 222 are connected to the processor 210 (not shown in the figure) so that the switch states of the first switch 221 and the second switch 222 are controlled by the processor 210.
As can be appreciated, referring to fig. 2, the first switch 221 has a parasitic diode P1, and the second switch 222 has a parasitic diode P2.
The power management module 230 supplies power to the logic unit 223 of the storage module 220 through the first power supply path or the second power supply path, and the power supply voltage of the first power supply path is smaller than the power supply voltage of the second power supply path. And, in case that the first switch 221 is in an on state and the second switch 222 is in an off state, the power management module 230 supplies power to the logic unit 223 of the memory module 220 through the first power supply path. With the first switch 221 in an off state and the second switch 222 in an on state, the power management module 230 supplies power to the logic unit 223 of the memory module 220 through the second power supply path.
The supply voltage of the first supply path is usually denoted as VDD2L, and VDD2L may be 0.9V. The supply voltage of the second supply path is typically denoted as VDD2H, VDD2H may be 1.05V. Specifically, in the case where the storage module 220 operates at the first frequency, the power management module 230 supplies power to the storage module 220 through the first power supply path. In the case where the storage module 220 operates at the second frequency, the power management module 230 supplies power to the storage module 220 through the second power supply path.
The power supply method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Please refer to fig. 3, which is a flowchart of a power supply method according to an embodiment of the present application. The method can be applied to electronic equipment, and the electronic equipment can be a mobile phone, a tablet personal computer, a notebook personal computer and the like. The electronic equipment comprises a storage module and a power management module, wherein the power management module is connected with the storage module, the power management module supplies power to the storage module through a first power supply path or a second power supply path, and the power supply voltage of the first power supply path is smaller than that of the second power supply path. For example, the supply voltage of the first supply path may be 0.9V and the supply voltage of the second supply path may be 1.05V. As shown in fig. 3, the method may include steps 3100 to 3300, which are described in detail below.
Step 3100, when the power management module supplies power to the storage module through a first power supply path and the storage module operates at a first frequency, receiving a first control instruction.
The first control instruction is used for controlling the storage module to switch to work at a second frequency, and the second frequency is higher than the first frequency in general. And the first control instruction can be actively triggered by a user or automatically triggered by the electronic equipment.
Referring to fig. 2, in the case where the memory module operates at the first frequency, the first switch is in an on state and the second switch is in an off state, and the power management module supplies power to the logic unit of the memory module through the first power supply path. At the same time, the processor receives a first control instruction for controlling the memory module to switch to the second frequency.
Step 3200, raising the power supply voltage of the first power supply channel by a first preset value, and enabling the storage module to work at a first frequency for a first preset period of time.
The first preset value is larger than the difference value between the power supply voltage of the second power supply path and the power supply voltage of the first power supply path. For example, the first preset value may be 0.2V. The design principle of the first preset value is that after the power supply voltage of the first power supply channel is increased by the first preset value, the power supply voltage of the first power supply channel is larger than the power supply voltage of the second power supply channel, so that when the power supply management module is switched to the second power supply channel to supply power to the storage module, the storage module works at the second frequency, although the second switch is in a conducting state and the first switch is in a disconnecting state, the parasitic diode P1 cannot be conducted in a micro-conduction mode, and no electric leakage occurs.
The first preset duration is determined according to a voltage change speed of the power management module, wherein the voltage change speed comprises at least one of the following steps: and increasing the speed of the first power supply path when the power supply voltage is supplied and the speed of the first power supply path when the first power supply path is switched to the second power supply path.
In this embodiment, after receiving the first control instruction for controlling the memory module to switch to the second frequency, the processor controls the power management module to increase the power supply voltage of the first power supply path by a first preset value, for example by 0.2V, and the memory module continues to operate at the first frequency for a first preset period of time, that is, the power management module supplies power to the memory module through the first power supply path for the first preset period of time.
It can be understood that, for example, when the time point at which the processor receives the first control instruction for controlling the storage module to switch to the second frequency is the T time point, and when the time point at which the processor controls the power management module to supply power to the storage module through the second power supply path is the T1 time point, at a T2 time point between the T time point and the T1 time point, the processor increases the power supply voltage of the first power supply path by a first preset value, and in this process, the storage module operates at the first frequency. In general, the time point T2 is related to a first voltage change speed of the power management module, where the first voltage change speed is a speed when the power management module increases the power supply voltage of the first power supply path.
Step 3200, controlling the power management module to supply power to the storage module through a second power supply path so as to enable the storage module to work at the second frequency.
In one embodiment, the controlling the power management module to supply power to the storage module through a second power supply path in step 3200 to enable the storage module to operate at the second frequency may further include: controlling the first switch to be switched off and controlling the second switch to be switched on; and under the condition that the first switch is in an off state and the second switch is in an on state, the power management module supplies power to the storage module through a second power supply path so as to enable the storage module to work at the second frequency.
Referring to fig. 2, the processor controls the first switch to be turned off and controls the second switch to be turned on, and the power management module supplies power to the logic unit of the memory module through the second power supply path so that the memory module operates at the second frequency, and since the power supply voltage of the first power supply path is increased to 1.1V and the power supply voltage of the second power supply path is increased to 1.05V, the voltage of the parasitic diode P1 is reversed at this time, and no micro-conduction condition can occur, so that no leakage phenomenon occurs. The power supply voltage of the first power supply path is increased, but the logic unit is not supplied with power, and the power consumption is not increased.
According to the embodiment of the application, under the condition that the power management module supplies power to the storage module through the first power supply channel and the storage module works at the first frequency, the electronic equipment can receive the first control instruction for controlling the storage module to switch to work at the second frequency, the power supply voltage of the first power supply channel is increased by a first preset value, the storage module works at the first frequency for a first preset duration, and then the power management module is controlled to supply power to the storage module through the second power supply channel, so that the storage module works at the second frequency. That is, according to the embodiment of the application, the power supply voltage of the original first power supply channel is increased within the first preset time period between the receiving of the first control instruction and the actual switching to the second power supply channel to supply power to the memory module so as to enable the memory module to work at the second frequency, so that the micro-conduction condition can not occur under the condition that the memory module is actually switched to the second power supply channel to supply power to the memory module to work at the second frequency, no leakage occurs, and the problem of leakage existing during DDR frequency switching is solved.
In one embodiment, after performing the above step 3300 to control the power management module to supply power to the storage module through the second power supply path, so that the storage module operates at the second frequency, the power supply method according to the embodiment of the present application further includes the following steps 4100 to 4300:
step 4100, accepting a second control instruction.
The second control instruction is used for controlling the storage module to switch to the first frequency to work. And the second control instruction can be actively triggered by a user or automatically triggered by the electronic equipment.
Specifically, when the memory module operates at the second frequency, the second switch is in an on state and the first switch is in an off state, and the power management module supplies power to the logic unit of the memory module through the second power supply path. At the same time, the processor receives a second control instruction for controlling the memory module to switch to the first frequency.
Step 4200, providing power to the memory module through the first power path to operate the memory module at the first frequency with the first switch in an on state and the second switch in an off state.
Referring to fig. 2, after receiving a second control instruction for controlling the memory module to switch to the first frequency, the processor controls the first switch to be turned on and controls the second switch to be turned off, and at this time, the power management module supplies power to the logic unit of the memory module through the first power supply path, so that the memory module operates at the first frequency.
Step 4300, reducing the supply voltage of the first supply path by the first preset value when the storage module operates at the first frequency for a second preset period of time.
Wherein the second preset time period is related to a speed at which the second switch is completely opened.
In this embodiment, after the storage module operates at the first frequency for a second preset period of time, the processor controls the power management module to reduce the power supply voltage of the first power supply path by a first preset value, for example, by 0.2V, that is, the power supply voltage of the first power supply voltage is 0.9V, so as to reduce power consumption.
