In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a power supply method for a power chip according to an embodiment of the present invention.
The power supply method of the power chip comprises the following steps:
step S1: pre-configuring a power supply for adapting to power supply requirements of different types of power chips; the power supply has different power supply grades when being adapted to the power supply requirements of any type of power chip.
Specifically, the power supply is configured on the server mainboard in advance, the power supply can adapt to the power supply requirements of different types of power chips, and different power supply grades exist when the power supply adapts to the power supply requirements of any type of power chip, so that a basis is provided for reasonably distributing power supply voltage according to the actual power consumption condition of the chip in the follow-up process.
Step S2: and acquiring the target type of the target power chip on the mainboard, and controlling the power supply to enter a power supply state adaptive to the power supply requirement of the target power chip according to the target type.
Specifically, the power chip currently set on the server motherboard is called a target power chip, and in consideration of different power supply requirements of different types of power chips, the target type of the target power chip is obtained in the present application, so as to control the power supply configured on the server motherboard to enter a power state adapted to the power supply requirement of the target power chip according to the target type of the target power chip, so as to subsequently meet the power supply requirement of the target power chip.
Step S3: the current power consumption of the target power chip is obtained, the target power supply grade corresponding to the current power consumption is determined according to the preset power consumption grade corresponding relation, and the power supply is controlled to supply power to the target power chip in the power supply state corresponding to the target power supply grade.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Specifically, the actual power consumption of the target power chip depends on the actual working state of the target power chip, which may be in a low-load working state, and at this time, the actual power consumption of the target power chip is also low; it may also be in a high load operating state, where the actual power consumption of the target power chip is also higher. It can be understood that when the actual power consumption of the target power chip is low, the currently required chip power supply is also low, i.e. the required power supply level is low; when the actual power consumption of the target power chip is higher, the currently required chip power supply is also higher, i.e. the required power supply level is higher. Therefore, the power consumption level corresponding relation set in advance in the application is as follows: the larger the actual power consumption of the target power chip is, the higher the corresponding power supply level of the power supply is.
Based on this, the current power consumption of the target power chip is obtained, the target power supply grade corresponding to the current power consumption of the target power chip is determined according to the preset power consumption grade corresponding relation, and then the power supply is controlled to supply power to the target power chip in the power supply state corresponding to the target power supply grade, so that the power supply voltage is reasonably distributed according to the actual power consumption condition of the chip, and the power supply voltage is fully utilized.
