These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
While the preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all alterations and modifications as fall within the scope of the application.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations as well.
Claims (10)
1. A processing method for simultaneous display of independent display cards and collective displays is characterized by comprising the following steps:

the system memory comprises two memory areas, wherein the state of one memory area is read-only, and the state of the other memory area is write; and the video memory area is synchronous with the image data in the memory area with the writing state.
2. The method according to claim 1, wherein before outputting the image data in the video memory area of the independent video card to the independent video card in a mirror image manner, the method further comprises:
acquiring first interface information output and displayed by an independent display card;
and acquiring second interface information output and displayed by the integrated display card.
3. The method according to claim 2, wherein outputting the image data in the video memory area of the independent video card to the independent video card comprises:
and outputting the image data in the video memory area of the independent video card to each outlet of the independent video card in a mirror image mode.
4. The method according to claim 3, wherein after the obtaining the second interface information output and displayed by the integrated graphics card, the method further comprises:
acquiring the resolution of a main screen;
according to the resolution of the main screen, applying for a video memory area in an independent video card;
and applying for two system memory areas in the system memory according to the resolution of the main screen.
5. The method according to claim 2, wherein outputting the image data in the video memory area of the independent video card to the independent video card comprises:
and outputting the image data in the video memory area of the independent video card to each outlet of the independent video card in sequence.
6. The method of claim 5, wherein after the obtaining the second interface information output and displayed by the integrated graphics card, further comprising:
calculating and saving the size of an output image according to the first interface information and the second interface information;
applying for a video memory area in the independent video card according to the size;
and applying for two system memory areas in the system memory according to the second interface information.
7. The method of claim 4 or 6, further comprising:
determining the current refreshing times N according to the refreshing rate period of the main screen;
if N%2= =0, marking a first block memory area of the system memory as read-only, and marking a second block memory area of the system memory as write;
if N%2! If =0, the second block memory area of the system memory is marked as read only, and the first block memory area of the system memory is marked as write.
8. The method of claim 7, further comprising:
storing image data in the video memory area;
and copying the image data in the video memory area to a memory area with a writing state.
9. An electronic device, comprising:
a memory;
a processor; and
a computer program;
wherein the computer program is stored in the memory and configured to be executed by the processor to implement the method of any one of claims 1-8.
10. A computer-readable storage medium, having stored thereon a computer program; the computer program is executed by a processor to implement the method of any one of claims 1-8.
