Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
The application discloses a processing method, which is applied to an electronic device, wherein the electronic device includes a first processor, a second processor, a first graphics processor and a second graphics processor, and a flowchart of the processing method disclosed in this embodiment is shown in fig. 1, and includes:
step S11, the first processor acquires first information, and the first information is used for switching a first graphics processor executing graphics processing tasks in the electronic equipment into a second graphics processor;
step S12, the second processor obtains the first information obtained by the first processor, and switches the first graphic processor into the second graphic processor according to the first information, so that the display screen of the electronic device can display and output in the second display mode when the second graphic processor executes the graphic processing task, where the display screen of the electronic device displays and outputs in the first display mode when the first graphic processor executes the graphic processing task, and the first display mode is different from the second display mode.
During operation of an electronic device, graphics processing tasks can generally be performed by only one graphics processor, such as: a graphics processor inside a CPU processor, i.e., an integrated graphics card IGPU, is commonly used in electronic devices; if the user starts a game or other professional software, an independent graphics processor, namely the independent display card DGPU is needed, and the independent display card executes graphics processing tasks, so that the display effect of the image displayed by the display screen can meet the requirement of the user, and the problem of poor display effect is avoided.
If the integrated display card is switched to the independent display card or the independent display card is switched to the integrated display card, the restart operation is inevitably required to be executed after the display card is switched, so that the user experience is reduced.
In order to avoid the foregoing situation, in the embodiment, in the operation process of the electronic device, if the first processor acquires the first information, that is, when the first processor acquires the information that needs to perform the graphics card switching operation, the information is sent to the second processor, and the second processor executes the subsequent operation.
The method comprises the steps that one or more specific programs in the running process of the electronic equipment are started, if the programs detect that the electronic equipment is connected with an integrated display card currently in the starting process, and the independent display card is installed in the electronic equipment, the programs can generate first information, send the first information to a first processor, then send the first information to a second processor through the first processor, and the second processor executes display card switching operation.
In this case, the first graphic processor may be an integrated graphic card, and the second graphic processor may be an independent graphic card. Typically the first graphics processor is less capable than the second graphics processor.
When the first processor determines that the currently running application program needs to start the second graphics processor, and the second graphics processor executes the graphics processing task, the first processor sends first information to the second processor, the second processor acquires the first information, and the first graphics processor executing the graphics processing task is switched to the second graphics processor based on the first information, so that the second graphics processor executes the graphics processing task.
Specifically, when the first graphic processor executes the graphic processing task, the display screen of the electronic device is output in a first display mode, and when the second graphic processor executes the graphic processing task, the display screen of the electronic device is output in a second display mode, wherein the first display mode is different from the second display mode.
When the first graphic processor executes the graphic processing task, the display mode of the electronic equipment is different from that when the second graphic processor executes the graphic processing task, so that the display screen of the electronic equipment can display the picture based on different display modes, and when the graphic processors are switched, the pictures are displayed in different display modes, thereby avoiding the switching of the display screen.
The second processor may specifically be: the system controller EC, the second processor is a processor for management control of the input/output device. When first information containing switching information is acquired, a second processor executes switching operation of the graphics processor; the first processor is a processor located at the bottom of the BIOS.
In addition, it may be: when an operating system of the electronic device detects that no specific game or specific application program runs in a current system, namely the integrated display card can complete a graphics processing task without the need of executing the graphics processing task by the independent display card, at this moment, the first graphics processor is the independent display card, and the second graphics processor is the integrated display card.
When the operating system determines that no program requiring the first graphics processor to execute graphics processing tasks exists currently, first information is generated and sent to the first graphics processor, the first information is sent to the second graphics processor through the first graphics processor, the second graphics processor switches the first graphics processor into the second graphics processor, namely the independent video card is switched into the integrated video card, and meanwhile, the display mode of the display screen is switched from the first display mode into the second display mode, so that the switching of the graphics processors can be completed without restarting the electronic equipment.
Further, the first display mode may be: the display screen is connected with the first graphic processor through a first display interface and outputs a mode of a graphic processing task executed by the first graphic processor through the display screen; the second display mode may be: the display screen is connected with the second graphic processor through the second display interface and outputs the mode of the graphic processing task executed by the second graphic processor through the display screen.
The first display interface and the second display interface are different interfaces connected with the display screen, wherein the first display interface can be an internal display interface, the second display interface is an external display interface, at the moment, the first graphic processor is an integrated display card, and the second graphic processor is an independent display card.
If the first graphic processor is connected with the display screen through the internal display interface, the internal monitoring module of the electronic device can monitor that the internal display interface is started, and data transmission can be performed, the electronic device can determine that the content acquired by the display screen through the internal display interface is the content to be displayed by the electronic device, namely when the content processed by the first graphic processor is connected with the display screen through the internal display interface, the internal monitoring module of the electronic device can monitor that the connected display interface is the internal display interface, and can determine that the data transmitted by the first graphic processor through the first display interface is the data of the device;
if the second graphic processor is connected with the display screen through the external display interface, the external monitoring module of the electronic device can monitor that the external display interface is started, and data transmission can be performed, the electronic device can determine that the content acquired by the display screen through the external display interface is the content to be displayed by the external device, namely when the content processed by the second graphic processor is connected with the display screen through the external display interface, the external monitoring module of the electronic device can monitor that the display interface of the interface is the external display interface, and can consider that the data transmitted by the second graphic processor through the second display interface is the data of the external device.
When the electronic equipment confirms that the content needing to be displayed on the display screen is sent by different equipment, the two graphic processors carry out real-time communication, the electronic equipment does not need to be restarted, and the content needing to be displayed can be processed and sent by the different equipment by directly switching the display interface. The first graphic processor of the electronic device is connected with the internal display interface of the display screen, the second graphic processor of the electronic device is connected with the external display interface of the display screen, and the first graphic processor and the second graphic processor belong to the same electronic device and are different graphic processors.
Further, the method also comprises the following steps:
if the first graphic processor is connected with the display screen through the internal display interface, the second graphic processor is connected with the display screen through the external display interface, when the content displayed on the display screen is the content transmitted by the second graphic processor through the external display interface, the third processor acquires brightness adjusting information and sends the brightness adjusting information to the second processor, and the second processor adjusts the brightness of the display screen according to the brightness adjusting information.
When the content displayed by the display screen is the content transmitted by the second graphic processor through the external display interface, the second graphic processor or the first graphic processor can consider that the second graphic processor is connected with the external display device through the external display interface because the second graphic processor is connected with the external display interface, so that the second graphic processor or the first graphic processor cannot acquire an adjusting instruction for the display device connected with the external display interface, cannot directly adjust the brightness of the display screen, and can only adjust the brightness of the display screen connected with the internal display interface.
Therefore, in the scheme, the brightness adjusting information is forwarded to the second processor through the third processor, after the second processor acquires the brightness adjusting information, the brightness of the display screen in the connection path in the starting state is directly controlled by the second processor, wherein the connection path in the starting state is the second graphic processor and the display screen which are connected through the external display interface, after the forwarded brightness adjusting information is acquired by the second processor, the brightness of the display screen is directly controlled, and the condition that the brightness of the display screen connected through the external display interface cannot be adjusted through the second processor is avoided.
The processing method disclosed in this embodiment is applied to an electronic device, where a first processor acquires first information, the first information is used to switch a first graphics processor, which executes a graphics processing task in the electronic device, to a second graphics processor, and a second processor acquires the first information acquired by the first processor, and switches the first graphics processor to the second graphics processor according to the first information, so that a display screen of the electronic device can display output in a second display mode when the second graphics processor executes the graphics processing task, where the display screen of the electronic device displays output in the first display mode when the first graphics processor executes the graphics processing task, and the first display mode is different from the second display mode. According to the scheme, the first information is acquired through the first processor, then the second processor switches the graphic processor according to the first information, so that the display screen can display and output according to the display mode corresponding to the current graphic processor, the display screen does not need to be switched, the graphic processor can be switched only by switching the corresponding display mode, the problem that the graphic processor can be switched by restarting the electronic equipment when the graphic processor is switched is avoided, and the user experience is improved.
The embodiment discloses a processing method, a flowchart of which is shown in fig. 2, and the processing method includes:
step S21, the first processor acquires first information, wherein the first information is used for switching a first graphics processor executing graphics processing tasks in the electronic equipment into a second graphics processor;
step S22, the second processor obtains the first information obtained by the first processor, closes the data transmission channel of the first graphic processor according to the first information, and simultaneously starts the data transmission channel of the second graphic processor, so that the display screen of the electronic device can display and output in the second display mode when the second graphic processor executes the graphic processing task, wherein the display screen of the electronic device displays and outputs in the first display mode when the first graphic processor executes the graphic processing task, and the first display mode is different from the second display mode.
When the first graphics processor is switched to the second graphics processor through the second processor, the data transmission channel of the first graphics processor is closed through the second processor, and meanwhile, the switching of the graphics processors is realized in a mode that the data transmission channel of the second graphics processor is started.
Specifically, the data transmission channel of the first graphic processor is a data transmission channel through which the first graphic processor transmits the processed data to the display screen, and the data transmission channel of the second graphic processor is a data transmission channel through which the second graphic processor transmits the processed data to the display screen.
If the first graphic processor is connected with the display screen through the first display interface and the second graphic processor is connected with the display screen through the second display interface, the data transmission channel of the first graphic processor is a channel through which the first graphic processor transmits the processed data to the display screen through the first display interface, and the data transmission channel of the second graphic processor is a channel through which the second graphic processor transmits the processed data to the display screen through the second display interface.
When the second processor switches the first graphic processor into the second graphic processor, the data transmission channel of the second graphic processor is directly started, and the data transmission channel of the first graphic processor is closed, so that the external display interface is monitored to be started through the external monitoring module, and if data is transmitted, the data transmission channel containing the external display interface is started to transmit data;
similarly, when the second processor switches the second graphic processor into the first graphic processor, the data transmission channel of the first graphic processor is directly started, and the data transmission channel of the second graphic processor is closed, so that the purpose that the internal display interface is monitored to be started through the internal monitoring module can be achieved, and when data is transmitted, the data transmission channel comprising the internal display interface is started to transmit data. It should be noted that different channels may communicate through the PCI bus of the device side, and may also be switched through USB, bluetooth, and the like, and the selection of the switched data path is based on the type and size of the data, and is not described herein.
The disconnection of the data transmission channel can be realized by directly closing the display interface corresponding to the data transmission channel, or by disconnecting the graphic processor corresponding to the data transmission channel in the data transmission channel, or by disconnecting the display interface corresponding to the data transmission channel in the data transmission channel;
starting the data transmission channel can be directly realized by starting the display interface corresponding to the data transmission channel, or can be realized by connecting a graphic processor corresponding to the data channel in the data channel, or by connecting the display interface corresponding to the data transmission channel in the data transmission channel. It should be noted that the selection of the data channel may also be detected by the update frequency of the image data, and in the case of high-frequency update, a channel with a high transmission rate may be used, and in the case of low update, a channel with a low transmission rate may also be selected, so as to achieve the purposes of reducing power consumption in real time and saving transmission data.
Further, the switching of the first graphics processor to the second graphics processor by the second processor may also be:
and the second processor acquires the processing result of the graphic processing task sent by the second graphic processor through the first graphic processor according to the first information so as to enable the display screen of the electronic equipment to display and output in a second display mode.
If the first graphics processor is an integrated graphics card and the second graphics processor is an independent graphics card, when the first graphics processor and the second graphics processor are connected with the display screen through the same interface, if the first graphics processor executes a graphics processing task, the first graphics processor directly sends a processing result obtained after the graphics processing task to the display screen through the display interface after executing the graphics processing task, and the processing result is displayed by the display screen; if the second graphics processor executes the graphics processing task, after the second graphics processor executes the graphics processing task, the processing result obtained after the graphics processing task is shared with the first graphics processor, and the first graphics processor sends the processing result to the display screen through the display interface and the display screen displays the processing result.
When the second processor switches the first graphic processor into the second graphic processor, the switching of the graphic processors can be realized by restarting the electronic device, or by starting a specific function module in the first graphic processor, the specific function module is used for acquiring a processing result of the second graphic processor and directly sending the processing result to the display screen through the display interface without processing the acquired processing result, so that the data transmission of the first graphic processor, the second graphic processor and the display screen is realized through one display interface.
The processing method disclosed in this embodiment is applied to an electronic device, where a first processor acquires first information, the first information is used to switch a first graphics processor, which executes a graphics processing task in the electronic device, to a second graphics processor, and a second processor acquires the first information acquired by the first processor, and switches the first graphics processor to the second graphics processor according to the first information, so that a display screen of the electronic device can display output in a second display mode when the second graphics processor executes the graphics processing task, where the display screen of the electronic device displays output in the first display mode when the first graphics processor executes the graphics processing task, and the first display mode is different from the second display mode. According to the scheme, the first information is acquired through the first processor, then the second processor switches the graphic processor according to the first information, so that the display screen can display and output according to the display mode corresponding to the current graphic processor, the display screen does not need to be switched, the graphic processor can be switched only by switching the corresponding display mode, the problem that the graphic processor can be switched by restarting the electronic equipment when the graphic processor is switched is avoided, and the user experience is improved.
The embodiment discloses a processing method, a flowchart of which is shown in fig. 3, and the processing method includes:
step S31, the first processor acquires first information, wherein the first information is used for switching a first graphics processor executing graphics processing tasks in the electronic equipment into a second graphics processor;
step S32, the second processor obtains the first information obtained by the first processor, and starts the data transmission channel of the second graphics processor according to the first information, so that the data transmission channel of the first graphics processor in the start state does not perform data transmission, and the display screen can display and output in the second display mode, where when the first graphics processor executes the graphics processing task, the display screen of the electronic device displays and outputs in the first display mode, and the first display mode is different from the second display mode.
When the second processor switches the first graphics processor to the second graphics processor, the data transmission channel where the second graphics processor is located may be started, and the data transmission channel where the first graphics processor is located may not be operated, that is, still be in a starting state, but the system may not transmit data through the data transmission channel where the first graphics processor is located.
The data transmission channel where the first graphic processor is located is always in a starting state, and when the data transmission channel where the second graphic processor is located is in a non-starting state, data are directly transmitted to the display screen through the data transmission channel where the first graphic processor is located; when the data transmission channel where the second graphic processor is located is in the starting state, even if the data transmission channel where the first graphic processor is located is still in the starting state, the system transmits data to the display screen through the data transmission channel where the second graphic processor is located.
Specifically, a data transmission channel for transmitting data to the display screen is controlled by the second processor, a control logic is built in the second processor, the data transmission channel where the second graphic processor is located is preferentially selected to transmit data to the display screen, and if the data transmission channel where the second graphic processor is located is in a closed state, the data transmission channel where the first graphic processor is located is selected to transmit data to the display screen. Therefore, when the second graphics processor is required to execute graphics processing tasks, the second graphics processor is directly started, and data transmission from the data transmission channel where the second graphics processor is located to the display screen can be realized; and when the second graphics processor is not required to execute the graphics processing task, transmitting data to the display screen by adopting the data transmission channel where the first graphics processor in the starting state is located.
Furthermore, a first switch device is arranged between the first graphic processor and the display screen, and the second graphic processor directly controls the on-off state of the first switch device.
Wherein, the switch state can be:
specifically, the first switch device may be a multiplexer MUX, and may select one of the multiple data transmission channels according to a requirement to perform data transmission, that is, select one of the data transmission channels where the first graphics processor is located or the data transmission channel where the second graphics processor is located to perform data transmission, and directly control the first switch device to be connected to the first graphics processor by the second processor EC, so that the data transmission channel where the first graphics processor is located transmits data to the display screen, or control the first switch device to be connected to the second graphics processor, so that the data transmission channel where the second graphics processor is located transmits data to the display screen.
The processing method disclosed in this embodiment is applied to an electronic device, where a first processor acquires first information, the first information is used to switch a first graphics processor, which executes a graphics processing task in the electronic device, to a second graphics processor, and a second processor acquires the first information acquired by the first processor, and switches the first graphics processor to the second graphics processor according to the first information, so that a display screen of the electronic device can display output in a second display mode when the second graphics processor executes the graphics processing task, where the display screen of the electronic device displays output in the first display mode when the first graphics processor executes the graphics processing task, and the first display mode is different from the second display mode. According to the scheme, the first information is acquired through the first processor, then the second processor switches the graphic processor according to the first information, so that the display screen can display and output according to the display mode corresponding to the current graphic processor, the display screen does not need to be switched, the graphic processor can be switched only by switching the corresponding display mode, the problem that the graphic processor can be switched by restarting the electronic equipment when the graphic processor is switched is avoided, and the user experience is improved.
The embodiment discloses a processing system applied to an electronic device, where the electronic device includes a first processor, a second processor, a first graphics processor and a second graphics processor, and a schematic structural diagram of the processing system disclosed in the embodiment is shown in fig. 4, and includes:
an acquisition unit 41 and a switching unit 42.
The obtaining unit 41 is configured to obtain first information through a first processor, where the first information is used to switch a first graphics processor that executes a graphics processing task in the electronic device to a second graphics processor;
the switching unit 42 is configured to obtain first information obtained by the first processor through the second processor, and switch the first graphics processor to the second graphics processor according to the first information, so that when the second graphics processor executes a graphics processing task, a display screen of the electronic device can display and output in a second display mode;
when the first graphics processor executes the graphics processing task, the display screen of the electronic device displays output in a first display mode, and the first display mode is different from the second display mode.
During operation of an electronic device, graphics processing tasks can generally be performed by only one graphics processor, such as: a graphics processor inside a CPU processor, i.e., an integrated graphics card IGPU, is commonly used in electronic devices; if the user starts a game or other professional software, an independent graphics processor, namely the independent display card DGPU is needed, and the independent display card executes graphics processing tasks, so that the display effect of the image displayed by the display screen can meet the requirement of the user, and the problem of poor display effect is avoided.
If the integrated display card is switched to the independent display card or the independent display card is switched to the integrated display card, the restart operation is inevitably required to be executed after the display card is switched, so that the user experience is reduced.
In order to avoid the foregoing situation, in the embodiment, in the operation process of the electronic device, if the first processor acquires the first information, that is, when the first processor acquires the information that needs to perform the graphics card switching operation, the information is sent to the second processor, and the second processor executes the subsequent operation.
The method comprises the steps that one or more specific programs in the running process of the electronic equipment are started, if the programs detect that the electronic equipment is connected with an integrated display card currently in the starting process, and the independent display card is installed in the electronic equipment, the programs can generate first information, send the first information to a first processor, then send the first information to a second processor through the first processor, and the second processor executes display card switching operation.
In this case, the first graphic processor may be an integrated graphic card, and the second graphic processor may be an independent graphic card. Typically the first graphics processor is less capable than the second graphics processor.
When the first processor determines that the currently running application program needs to start the second graphics processor, and the second graphics processor executes the graphics processing task, the first processor sends first information to the second processor, the second processor acquires the first information, and the first graphics processor executing the graphics processing task is switched to the second graphics processor based on the first information, so that the second graphics processor executes the graphics processing task.
Specifically, when the first graphic processor executes the graphic processing task, the display screen of the electronic device is output in a first display mode, and when the second graphic processor executes the graphic processing task, the display screen of the electronic device is output in a second display mode, wherein the first display mode is different from the second display mode.
When the first graphic processor executes the graphic processing task, the display mode of the electronic equipment is different from that when the second graphic processor executes the graphic processing task, so that the display screen of the electronic equipment can display the picture based on different display modes, and when the graphic processors are switched, the pictures are displayed in different display modes, thereby avoiding the switching of the display screen.
The second processor may specifically be: the system controller EC, the second processor is a processor for management control of the input/output device. When first information containing switching information is acquired, a second processor executes switching operation of the graphics processor; the first processor is a processor located at the bottom of the BIOS.
In addition, it may be: when an operating system of the electronic device detects that no specific game or specific application program runs in a current system, namely the integrated display card can complete a graphics processing task without the need of executing the graphics processing task by the independent display card, at this moment, the first graphics processor is the independent display card, and the second graphics processor is the integrated display card.
When the operating system determines that no program requiring the first graphics processor to execute graphics processing tasks exists currently, first information is generated and sent to the first graphics processor, the first information is sent to the second graphics processor through the first graphics processor, the second graphics processor switches the first graphics processor into the second graphics processor, namely the independent video card is switched into the integrated video card, and meanwhile, the display mode of the display screen is switched from the first display mode into the second display mode, so that the switching of the graphics processors can be completed without restarting the electronic equipment.
Further, the first display mode may be: the display screen is connected with the first graphic processor through a first display interface and outputs a mode of a graphic processing task executed by the first graphic processor through the display screen; the second display mode may be: the display screen is connected with the second graphic processor through the second display interface and outputs the mode of the graphic processing task executed by the second graphic processor through the display screen.
The first display interface and the second display interface are different interfaces connected with the display screen, wherein the first display interface can be an internal display interface, the second display interface is an external display interface, at the moment, the first graphic processor is an integrated display card, and the second graphic processor is an independent display card.
If the first graphic processor is connected with the display screen through the internal display interface, the internal monitoring module of the electronic device can monitor that the internal display interface is started, and data transmission can be performed, the electronic device can determine that the content acquired by the display screen through the internal display interface is the content to be displayed by the electronic device, namely when the content processed by the first graphic processor is connected with the display screen through the internal display interface, the internal monitoring module of the electronic device can monitor that the connected display interface is the internal display interface, and can determine that the data transmitted by the first graphic processor through the first display interface is the data of the device;
if the second graphic processor is connected with the display screen through the external display interface, the external monitoring module of the electronic device can monitor that the external display interface is started, and data transmission can be performed, the electronic device can determine that the content acquired by the display screen through the external display interface is the content displayed by the external device, namely when the content processed by the second graphic processor is connected with the display screen through the external display interface, the external monitoring module of the electronic device can monitor that the display interface of the interface is the external display interface, and can consider that the data transmitted by the second graphic processor through the second display interface is the data of the external device.
When the electronic equipment confirms that the content needing to be displayed on the display screen is sent by different equipment, the two graphic processors carry out real-time communication, the electronic equipment does not need to be restarted, and the content needing to be displayed can be processed and sent by the different equipment by directly switching the display interface. The first graphic processor of the electronic device is connected with the internal display interface of the display screen, the second graphic processor of the electronic device is connected with the external display interface of the display screen, and the first graphic processor and the second graphic processor belong to the same electronic device and are different graphic processors.
Further, the method also comprises the following steps:
if the first graphic processor is connected with the display screen through the internal display interface, the second graphic processor is connected with the display screen through the external display interface, when the content displayed on the display screen is the content transmitted by the second graphic processor through the external display interface, the third processor acquires brightness adjusting information and sends the brightness adjusting information to the second processor, and the second processor adjusts the brightness of the display screen according to the brightness adjusting information.
When the content displayed by the display screen is the content transmitted by the second graphic processor through the external display interface, the second graphic processor or the first graphic processor can consider that the second graphic processor is connected with the external display device through the external display interface because the second graphic processor is connected with the external display interface, so that the second graphic processor or the first graphic processor cannot acquire an adjusting instruction for the display device connected with the external display interface, cannot directly adjust the brightness of the display screen, and can only adjust the brightness of the display screen connected with the internal display interface.
Therefore, in the scheme, the brightness adjusting information is forwarded to the second processor through the third processor, after the second processor acquires the brightness adjusting information, the brightness of the display screen in the connection path in the starting state is directly controlled by the second processor, wherein the connection path in the starting state is the second graphic processor and the display screen which are connected through the external display interface, after the forwarded brightness adjusting information is acquired by the second processor, the brightness of the display screen is directly controlled, and the condition that the brightness of the display screen connected through the external display interface cannot be adjusted through the second processor is avoided.
Further, the switching unit 42 is configured to: and closing the data transmission channel of the first graphic processor through the second graphic processor according to the first information, and simultaneously starting the data transmission channel of the second graphic processor.
When the first graphics processor is switched to the second graphics processor through the second processor, the data transmission channel of the first graphics processor is closed through the second processor, and meanwhile, the switching of the graphics processors is realized in a mode that the data transmission channel of the second graphics processor is started.
Specifically, the data transmission channel of the first graphic processor is a data transmission channel through which the first graphic processor transmits the processed data to the display screen, and the data transmission channel of the second graphic processor is a data transmission channel through which the second graphic processor transmits the processed data to the display screen.
If the first graphic processor is connected with the display screen through the first display interface and the second graphic processor is connected with the display screen through the second display interface, the data transmission channel of the first graphic processor is a channel through which the first graphic processor transmits the processed data to the display screen through the first display interface, and the data transmission channel of the second graphic processor is a channel through which the second graphic processor transmits the processed data to the display screen through the second display interface.
When the second processor switches the first graphic processor into the second graphic processor, the data transmission channel of the second graphic processor is directly started, and the data transmission channel of the first graphic processor is closed, so that the external display interface is monitored to be started through the external monitoring module, and if data is transmitted, the data transmission channel containing the external display interface is started to transmit data;
similarly, when the second processor switches the second graphic processor into the first graphic processor, the data transmission channel of the first graphic processor is directly started, and the data transmission channel of the second graphic processor is closed, so that the purpose that the internal display interface is monitored to be started through the internal monitoring module can be achieved, and when data is transmitted, the data transmission channel comprising the internal display interface is started to transmit data. It should be noted that different channels may communicate through the PCI bus of the device side, and may also be switched through USB, bluetooth, and the like, and the selection of the switched data path is based on the type and size of the data, and is not described herein.
The disconnection of the data transmission channel can be realized by directly closing the display interface corresponding to the data transmission channel, or by disconnecting the graphic processor corresponding to the data transmission channel in the data transmission channel, or by disconnecting the display interface corresponding to the data transmission channel in the data transmission channel;
starting the data transmission channel can be directly realized by starting the display interface corresponding to the data transmission channel, or can be realized by connecting a graphic processor corresponding to the data channel in the data channel, or by connecting the display interface corresponding to the data transmission channel in the data transmission channel. It should be noted that the selection of the data channel may also be detected by the update frequency of the image data, and in the case of high-frequency update, a channel with a high transmission rate may be used, and in the case of low update, a channel with a low transmission rate may also be selected, so as to achieve the purposes of reducing power consumption in real time and saving transmission data.
Further, the switching of the first graphics processor to the second graphics processor by the second processor may also be:
and the second processor acquires the processing result of the graphic processing task sent by the second graphic processor through the first graphic processor according to the first information so as to enable the display screen of the electronic equipment to display and output in a second display mode.
If the first graphics processor is an integrated graphics card and the second graphics processor is an independent graphics card, when the first graphics processor and the second graphics processor are connected with the display screen through the same interface, if the first graphics processor executes a graphics processing task, the first graphics processor directly sends a processing result obtained after the graphics processing task to the display screen through the display interface after executing the graphics processing task, and the processing result is displayed by the display screen; if the second graphics processor executes the graphics processing task, after the second graphics processor executes the graphics processing task, the processing result obtained after the graphics processing task is shared with the first graphics processor, and the first graphics processor sends the processing result to the display screen through the display interface and the display screen displays the processing result.
When the second processor switches the first graphic processor into the second graphic processor, the switching of the graphic processors can be realized by restarting the electronic device, or by starting a specific function module in the first graphic processor, the specific function module is used for acquiring a processing result of the second graphic processor and directly sending the processing result to the display screen through the display interface without processing the acquired processing result, so that the data transmission of the first graphic processor, the second graphic processor and the display screen is realized through one display interface.
Further, the switching unit 42 is configured to: and starting the data transmission channel of the second graphic processor through the second processor according to the first information, so that the data transmission channel of the first graphic processor in the starting state does not transmit data.
When the second processor switches the first graphics processor to the second graphics processor, the data transmission channel where the second graphics processor is located may be started, and the data transmission channel where the first graphics processor is located may not be operated, that is, still be in a starting state, but the system may not transmit data through the data transmission channel where the first graphics processor is located.
The data transmission channel where the first graphic processor is located is always in a starting state, and when the data transmission channel where the second graphic processor is located is in a non-starting state, data are directly transmitted to the display screen through the data transmission channel where the first graphic processor is located; when the data transmission channel where the second graphic processor is located is in the starting state, even if the data transmission channel where the first graphic processor is located is still in the starting state, the system transmits data to the display screen through the data transmission channel where the second graphic processor is located.
Specifically, a data transmission channel for transmitting data to the display screen is controlled by the second processor, a control logic is built in the second processor, the data transmission channel where the second graphic processor is located is preferentially selected to transmit data to the display screen, and if the data transmission channel where the second graphic processor is located is in a closed state, the data transmission channel where the first graphic processor is located is selected to transmit data to the display screen. Therefore, when the second graphics processor is required to execute graphics processing tasks, the second graphics processor is directly started, and data transmission from the data transmission channel where the second graphics processor is located to the display screen can be realized; and when the second graphics processor is not required to execute the graphics processing task, transmitting data to the display screen by adopting the data transmission channel where the first graphics processor in the starting state is located.
