and after the switching to the first processing mode is determined, stopping executing the refreshing mode through the central control board so as to cancel the frozen state of the display screen of the target task.
3. The method of claim 1, wherein sending the first switching signal to the logic gate circuit over the target communication line to cause the logic gate circuit to generate the first switching instruction further comprises:
and calling an instruction code prestored in the BIOS, and generating the first switching signal according to a switching request sent by a first display card driver, wherein the switching request is generated based on the target task, and the instruction code is called by an ACPI driver.
4. The method of claim 3, further comprising:
sending a second switching signal to the logic gate circuit through the BIOS if the operand of the target task is greater than a first threshold value, so that the logic gate circuit generates the first switching instruction based on the first switching signal and the second switching signal;
and executing a first switching operation based on the first switching instruction so as to switch the processing mode of the display card to a first processing mode.
5. The method of claim 1, wherein sending the first switching signal to the logic gate circuit via the target communication line causes the logic gate circuit to generate a first switching command, specifically:
sending the first switching signal to the logic gate circuit through the first communication line or the second communication line to cause the logic gate circuit to generate a first switching instruction.
6. The method of claim 1, further comprising:
and sending the display picture of the target task acted and processed by the first video card to a display device, so that the display device displays the display picture of the target task acted and processed by the first video card.
7. The method of claim 1, further comprising:
under the condition that the operand of the target task is not larger than a first threshold value, sending a third switching signal to the logic gate circuit through the BIOS so that the logic gate circuit generates a second switching instruction;
and executing a second switching operation based on the second switching instruction so as to switch the processing mode of the display card to a second processing mode, wherein the second processing mode is a mode of using a second display card to act on the plurality of display cards and process the target task.
8. The method of claim 7, further comprising:
when it is determined that the logic gate circuit does not receive the first switching signal, a second switching operation is performed to switch to a second processing mode.
9. The method of claim 6, further comprising:
and sending the display picture of the target task acted and processed by the second video card to a display device, so that the display device displays the display picture of the target task acted and processed by the second video card.
10. An electronic device, comprising:
the switching module is used for acquiring a target task; freezing a display picture of the target task and sending a first switching signal to a logic gate circuit through a target communication line so that the logic gate circuit generates a first switching instruction when the calculation amount of the target task is larger than a first threshold value;
and the processing module is used for executing a first switching operation based on the first switching instruction so as to switch the processing mode of the display card to a first processing mode and cancel the frozen state of the display picture of the target task, wherein the first processing mode is a mode in which the target task is processed by a first display card in the plurality of display cards.
