It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The method for switching the mode of the video card in the low power scene provided by the present invention can be applied to the application environment shown in fig. 1, and the method for switching the mode of the video card in the low power scene is applied to the terminal 102, wherein the terminal 102 can be, but not limited to, a computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation terminal, a wearable device, a smart band, a pedometer, and other notebook terminals, and fixed terminals such as a Digital TV, a desktop computer, and the like.
In one or more embodiments of the present invention, as shown in fig. 2, a method for switching modes of a graphics card in a low power scene is provided, where a terminal is provided with a battery and a graphics card, and the graphics card has a plurality of interfaces; taking the application of the method to the notebook terminal in fig. 1 as an example for explanation, the method comprises the following steps:
step S1: when the notebook computer terminal is connected with the power supply, the electric quantity value of the battery is acquired within a preset interval time, and the method specifically comprises the following steps:
and the embedded controller of the terminal polls the electric quantity value of the battery in real time through a system management bus SMBUS of the battery, wherein the polling period is 1-5 seconds each.
Step S2: comparing the electric quantity value obtained each time with a first preset electric quantity threshold value;
in this embodiment, the first preset electric quantity threshold is preferably 25%.
Step S3: when the electric quantity value is smaller than a first preset electric quantity threshold value, the notebook terminal generates a mode switching command, and the method comprises the following steps:
step 301: and the embedded controller of the notebook computer terminal inquires the comparison relation between the preset electric quantity value and the working parameter of the display card according to the electric quantity value and reads the corresponding working parameter information, wherein the working parameter information comprises reference voltage and/or frequency. The comparison relationship between the electric quantity value and the operating parameter of the display card in the embodiment of the invention is shown in the following table 1.
TABLE 1
| Functional modes | P0 | P1 | P2 | P3 | P4 | P5 |
| Electric quantity value | 25％ | 22％ | 18％ | 15％ | 12％ | 8％ |
| Reference voltage | 0.9625V | 0.9500V | 0.9375V | 0.9125V | 0.8875V | 0.8625V |
| Frequency of | 2800 | 2500 | 2380 | 2100 | 1680 | 1400 |
In the embodiment of the present invention, the first preset point electric quantity threshold is 25%, and as can be seen from the above table, when the electric quantity value of the battery decreases to 25% of the first preset point electric quantity threshold, at this time, the electric quantity of the battery is considered to be at a low level, and the embedded controller of the notebook terminal needs to control the display card to switch to a low power consumption state. Aiming at different electric quantity values, a plurality of low-power consumption modes are set, for example, six low-power consumption modes P0-P5 are set, and the corresponding low-power consumption modes are sequentially switched along with the gradual reduction of the electric quantity values. Through the table 1, the corresponding low power consumption mode and the operating parameter (such as the reference voltage and/or the frequency) corresponding to the low power consumption mode can be read according to the electric quantity value, so that the corresponding interface level coding information can be read subsequently according to the operating parameter corresponding to the low power consumption mode.
Step 302: and the embedded controller of the notebook computer terminal inquires a preset level state truth table according to the working parameter information and acquires corresponding target interface level coding information.
Here, the interface level coding information is a combination of level states of all interfaces, for example, in the field of circuit technology, a low level is generally represented by "0" and a high level is generally represented by "1". Here, a binary-like interface level coding information may be formed according to the level state combination of all interfaces, and the bit number of the level coding information is the same as the number of the interfaces and corresponds to one, so that the level state to which the corresponding interface needs to be adjusted can be known according to the interface level coding information. In the embodiment of the present invention, the predetermined level truth table is shown in table 2 below.
TABLE 2
In the embodiment of the invention, taking an N16P-GX graphics card of NVIDIA corporation as an example, the N16P-GX graphics card is provided with 6 GPIO ports, and the reference voltage of the graphics card is adjusted by controlling the level state of each port, so as to control the low power consumption mode of the graphics card. For example, when the power value is decreased to 25%, the corresponding low power mode is P0, the reference voltage is 0.9625V, and the level truth table shows that the corresponding target level code information is 110101, i.e., the level states of the interfaces 0-5 are high level, low level, and high level.
Step 303: and the embedded controller of the notebook terminal acquires the current level states of all the interfaces, generates current interface level coding information and generates a switching command according to the current interface level coding information and the target interface level coding information.
Through the preset low-power-consumption parameter comparison table and the level state truth table, corresponding working parameter information can be read according to the electric quantity value when the electric quantity value is smaller than the first preset electric quantity threshold value, and then level coding information of the target interface is obtained, so that the level state of the corresponding interface can be conveniently adjusted according to the level coding information of the target interface subsequently, and the switching of the corresponding low-power-consumption mode is realized.
Here, also taking a 25% electric quantity value as an example, the target level coding information obtained in the step 302 is 110101, at this time, the embedded controller of the terminal reads the level states of all current interfaces, for example, the current level coding information of the interfaces 0 to 6 is 101100, at this time, the target level coding information obtained in the step 302 is compared with the current level coding information, and it is found that the level states of the interface 1, the interface 2, and the interface 5 of the video card need to be adjusted, therefore, a switching command can be generated according to the port that needs to be adjusted and the corresponding high-low level switching information, which is convenient for the embedded controller to adjust the level state of the corresponding port according to the switching command, so that after adjustment, the level turntable combination of all the ports is consistent with the target level coding information obtained in the step 302.
Step S4: and the notebook terminal adjusts the level states of the plurality of interfaces of the display card according to the mode switching command. Specifically, adjusting the level states of the plurality of interfaces of the graphics card according to the switching command specifically includes the following steps:
s401: and the embedded controller of the notebook computer executes a switching command according to the level coding information of the target interface so as to adjust the level state of the corresponding interface, so that the level state combination of all the interfaces is consistent with the level coding information of the target interface.
Here, the embedded controller reads the level code information of the target interface according to the switching command, or reads the level code of the target interface to 110101 according to the switching command by taking 25% of electric quantity value as an example; and the current level coding information is 101100, and the level states of the interface 1, the interface 2 and the interface 5 of the display card need to be adjusted to make the current level state combination of all the interfaces consistent with the level coding information of the target interface, so that the switching of the low power consumption mode is realized.
Here, according to the situation in the above embodiment, the level states of the interface 1, the interface 2 and the interface 5 of the graphics card need to be adjusted, and then the embedded controller controls the high and low level reverse switching of the interface 1, the interface 2 and the interface 5 of the graphics card, so that the level state combination of all the interfaces is consistent with the target level coding information, and thus, the reference voltage of the graphics card will be 0.9625V, and the graphics card immediately enters the low power consumption P0 mode.
Then, step S5 is executed to determine the reference voltage of the graphics card based on the adjusted level state.
And finally, executing a step S6, and controlling the display card to enter a corresponding low power consumption mode according to the reference voltage.
Optionally, in the embodiment of the present invention, when the electric quantity value is smaller than a second preset electric quantity threshold, a power cut-off command is generated, and the power of the graphics card is turned off according to the power cut-off command, where the second preset electric quantity threshold is smaller than the first preset electric quantity threshold.
Like this, when the electric quantity value further drops to being less than the second and predetermine the electric quantity threshold value, at this moment, the electric quantity of battery can not support the display card and normally work, through generating the cut-off command, controls the power that cuts off the display card, avoids the display card to last to be in performance mode, also can avoid the battery to discharge excessively simultaneously and lead to reducing its life-span.
For example, when the electric quantity value is reduced to 5%, the electric quantity of the battery is considered to be almost exhausted, so that the power supply is directly turned off at the moment in order to avoid the display card being in a low-performance state for a long time and avoid the damage caused by the transient discharge of the surface battery to influence the service life.
In practice, an MOS transistor can be used as a switch for switching on or off, a gate electrode of the MOS transistor is electrically connected with a control end of an embedded controller, a source electrode of the MOS transistor is electrically connected with a power input end of a display card, and a drain electrode of the MOS transistor is electrically connected with a reference voltage input end of the display card, so that during normal operation, the embedded controller controls the gate electrode of the MOS transistor to be at a high level, the MOS transistor is switched on, and a reference voltage of the drain electrode of the MOS transistor is led to be led to a power input end VCC of the display card; when the electric quantity value is reduced to 5%, in order to save electricity, the embedded controller controls the gate pole low level of the MOS tube, the MOS tube is cut off, and the reference voltage of the drain electrode of the MOS tube cannot be led into the power input end of the display card, so that the power of the display card is cut off.
In the above, one of the hardware ways is to turn off the power supply of the graphics card, but in practice, other hardware ways or software ways may also be used to turn off the power supply of the graphics card, and a detailed description thereof is omitted here.
The embodiment provides a display card mode switching method based on a terminal, which includes the steps of acquiring an electric quantity value of a battery in real time, and controlling level states of a plurality of interfaces of a display card by generating corresponding switching commands when the electric quantity value is smaller than a first preset electric quantity threshold value, so that the display card is adjusted to enter a corresponding low-power-consumption mode, the display card can be dynamically switched to the corresponding low-power-consumption mode when the electric quantity of the battery is low, the endurance time of the battery is prolonged, the waste of power consumption and the reduction of the endurance time caused by the fact that the display card works in a high-power-consumption state for a long time are avoided, and the service life of the display card is shortened.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
