The same reference numerals generally refer to the same components or elements.

[0024] First reference Figure 1 , Figure 1 1 shows a schematic diagram of a computing device 100 according to an exemplary embodiment of the present invention. Figure 1 As shown, the computing device 100 includes an internal memory 111, an external memory 112, and a central processing unit 113. The internal memory 111 includes, but is not limited to, volatile storage (e.g., random access memory), non-volatile storage (e.g., read-only memory), flash memory, or any combination of such memories. The external memory 112 refers to storage other than the internal memory 111 and the cache of the central processing unit 113, and can be specifically implemented as a hard disk, floppy disk, optical disk, USB flash drive, etc. The central processing unit 113 is the computing core and control core of the computing device 100, and is used to parse computer instructions and process data in computer software.

[0025] According to one embodiment of the present invention, the computing device may also include an integrated graphics card (not shown) integrated into the computing device. The graphics processor in the integrated graphics card can also process images, but if the computing device's external graphics card 140 has greater computing power, graphics card 140 may be preferred for data processing in most cases. The graphics card 140, which is in communication with the computing device 100, includes display memory 141 and a graphics processor 142. Display memory 141 is memory built into the graphics card 140 and is used to store rendering data processed or to be extracted by the graphics processor 142. The graphics processor 142 is a microprocessor that performs image and graphics-related operations.

[0026] Computing device 100 also runs an operating system 120 based on the aforementioned components, which is suitable for controlling the operation of computing device 100. Furthermore, examples may be implemented in conjunction with graphics libraries, other operating systems, or any other application, and are not limited to any particular application or system. The present invention is not limited to the specific type of operating system 120. Computing device 100 may also run one or more applications (not shown) based on operating system 120. The present invention does not limit the number or type of applications running on computing device 100. For example, the applications may be implemented as email and contact applications, word processing applications, spreadsheet applications, database applications, slide show applications, drawing or computer-aided applications, web browser applications, and the like.

[0027] According to one aspect, the computing device 100 may also be connected to one or more input devices 131, such as a keyboard, mouse, pen, voice input device, touch input device, etc. One or more output devices 132 may also be connected, such as a display, speakers, printer, etc. The aforementioned devices are examples, and other devices may also be used. The computing device 100 may include one or more communication connections that allow communication with other computing devices. Examples of suitable communication connections include, but are not limited to: RF transmitter, receiver, and / or transceiver circuitry; Universal Serial Bus (USB), parallel, and / or serial ports.

[0028] An embodiment of the present invention also provides a non-transitory readable storage medium storing instructions for causing the computing device to execute a method according to an embodiment of the present invention. The readable medium of this embodiment includes permanent and non-permanent, removable and non-removable media, and information storage can be implemented by any method or technology. The information can be a computer-readable instruction, a data structure, a program module, or other data. Examples of readable storage media include, but are not limited to: phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disc read-only memory (CD-ROM), digital versatile disc (DVD) or other optical storage, magnetic cassettes, tape disk storage or other magnetic storage devices, or any other non-transitory readable storage medium.

[0029] According to one aspect, communication media is implemented by computer-readable instructions, data structures, program modules, or other data in a modulated data signal (e.g., a carrier wave or other transport mechanism), and includes any information delivery media. According to one aspect, the term "modulated data signal" describes a signal that has one or more characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency (RF), infrared, and other wireless media.

[0030] According to one embodiment of the present invention, the computing device 100 and the graphics card 140 can be communicatively connected via a PCIE interface, etc. The present invention does not limit the specific method of connecting the computing device 100 and the graphics card 140. Since the computing device 100 and the graphics card 140 can actually be connected in a variety of different ways, the data communication speed between the computing device 100 and the graphics card 140 is also related to the connection method, sometimes fast and sometimes slow. When the data communication speed between the computing device 100 and the graphics card 140 is slow, if the display data is still stored in the display memory 141, the data processing speed requirement of the graphics card 140 cannot be met, thereby reducing the data processing speed of the graphics card 140.

[0031] In order to achieve a higher image processing speed for the graphics card 140, the present invention provides an image display method 200. The image display method of the present invention is suitable for execution in a computing device, such as the computing device 100.

[0032] Now refer to Figure 2 , Figure 2 FIG. 2 is a flow chart of an image display method 200 according to an exemplary embodiment of the present invention. Figure 2 As shown, step S210 is first executed to test a first writing speed of the central processing unit writing data into the internal memory and a second writing speed of the central processing unit writing data into the display memory.

[0033] According to one embodiment of the present invention, when testing the first write speed, a test memory is applied for in the internal memory to perform a data write test; when testing the second write speed, a driver of the graphics card 140 is called to apply for a test memory in the display memory to perform a test.

[0034] According to an embodiment of the present invention, the first write speed and the second write speed may specifically be the amount of data written per unit time, or the test time obtained by fixing the amount of data written.

[0035] Then, step S220 is executed to test a first reading speed of the graphics processor for reading data from the internal memory and a second reading speed of the graphics processor for reading data from the display memory.

[0036] According to one embodiment of the present invention, the first read speed and the second read speed may specifically refer to the amount of data read per unit time, or the test time obtained by fixing the amount of data read. When the first write speed and the second write speed specifically refer to the amount of data written per unit time, the first read speed and the second read speed specifically refer to the amount of data read per unit time. When the first write speed and the second write speed specifically refer to the test time obtained by fixing the amount of data written, the first read speed and the second read speed specifically refer to the test time obtained by fixing the amount of data read.

[0037] According to an embodiment of the present invention, the memory size requested from the internal memory or the display memory can be configured as needed, such as customized by the user.

[0038] According to one embodiment of the present invention, when the configured memory size does not comply with the rules, is too small (such as 0) or too large, and exceeds the memory size that can be tested, so that the write speed or read speed cannot be correctly tested, the memory for applying for memory can be set according to the default value, such as internal memory or display memory.

[0039] Subsequently, step S230 is executed to determine a preferred memory option based on the first write speed, the second write speed, the first read speed, and the second read speed. The preferred memory option includes internal memory or display memory. Specifically, first, a first parameter of the internal memory is calculated based on the first write speed and the first read speed. According to one embodiment of the present invention, the first parameter can be obtained by adding the first write speed and the first read speed; it can also be obtained by averaging the first write speed and the first read speed. The present invention does not limit the specific calculation method of the first parameter.

[0040] Next, a second parameter of the display memory is calculated based on the second write speed and the second read speed. According to one embodiment of the present invention, the second parameter can be obtained by adding the second write speed and the second read speed, or by averaging the second write speed and the second read speed. The present invention does not limit the specific method for calculating the second parameter.

[0041] Third, the memory priority option is determined based on the first parameter and the second parameter. Specifically: first, the first parameter is compared with the second parameter to obtain a speed ratio, and then the speed ratio is compared with a preset ratio threshold. If the speed ratio is greater than the preset ratio threshold, the internal memory is determined as the memory priority option; if the speed ratio is equal to or less than the preset ratio threshold, the display memory is determined as the memory priority option. If the speed ratio is greater than the preset ratio threshold, it means that when the central processing unit stores the display data in the internal memory, the graphics card is more efficient in obtaining the display data, and the display data is preferentially stored in the internal memory; the graphics card is able to obtain the display data from the internal memory.

[0042] If the speed ratio is equal to or less than the preset ratio threshold, it means that when the central processor stores the display data in the display memory, the graphics card obtains the display data more efficiently, so the display data is stored in the internal memory first; the graphics card can obtain the display data from the internal memory.

[0043] According to an embodiment of the present invention, the preset ratio threshold may be set to 1.

[0044] According to an embodiment of the present invention, steps S310 to S330 of the present invention may be executed by a preset memory test application, and the preset memory test application may also be integrated into a preset memory test tool.

[0045] According to one embodiment of the present invention, a preset memory test application can be set to start when the computing device is turned on. When the computing device is turned on, the graphics card 140 driver is initialized, and the test environment preparation work of the preset memory test application is completed, the preset memory test application begins to execute and test the read and write speeds of various memory devices.

[0046] Now refer to Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of a memory test according to an exemplary embodiment of the present invention. Figure 3 As shown, during the test, a preset memory test program is started, and memory in the internal memory and display memory are requested separately. The CPU writes data to the internal memory for a test, obtaining a speed s1, and writes data to the display memory for a test, obtaining a speed s2. The graphics processor then reads data from the internal memory for a test, obtaining a speed s3, and reads data from the graphics processor for a test, obtaining a speed s4. Subsequently, speeds s1 and s3 are added together to obtain a first parameter, and speeds s2 and s4 are added together to obtain a second parameter.

[0047] The first parameter is then compared with the second parameter to obtain a comparison result x. The comparison result x is compared with a preset ratio threshold n: if the comparison result x is greater than the preset ratio threshold n, the internal memory is determined as the target memory; if the comparison result x is less than or equal to the preset ratio threshold n, the display memory is determined as the target memory.

[0048] Then, step S240 is executed, when an image processing request is received, a target memory is determined according to the memory preference option, and the image data is stored in the target memory. When an image processing request is received, a memory is requested to store the image data, and the image data is stored in the requested memory.

[0049] When requesting memory, it is necessary to determine whether to request from internal memory or display memory. Specifically, it is determined whether the memory priority flag is set. The memory priority flag includes either the display memory flag or the internal memory flag. The memory priority flag is a flag pre-stored in a register that indicates whether to request memory from internal memory or display memory. If the memory priority flag is set, the target register is determined based on the memory priority flag.

[0050] If the memory preference flag is not set, a memory preference option is obtained, and the memory preference flag is set according to the memory preference option, and then the target memory is determined according to the memory preference flag.

[0051] When setting the memory priority flag, if the memory priority option is display memory, set the memory priority flag to the display memory flag; if the memory priority option is internal memory, set the memory priority flag to the internal memory flag. Setting the memory priority flag can facilitate the determination of the target register, eliminating the need to obtain the memory priority option each time a memory request is made, thus improving memory request speed.

[0052] According to one embodiment of the present invention, after determining the memory preferred option, the preset memory test program generates a test result file for storing the memory preferred option, so that after receiving an image processing request, the test result file is read to determine the memory preferred option.

[0053] When determining the target memory according to the memory priority identification bit, if the memory priority identification bit is the display memory identification bit, the display memory is used as the target memory; if the memory priority identification bit is the internal memory, the internal memory is used as the target memory.

[0054] Now refer to Figure 4 , Figure 4 FIG. 1 shows a schematic diagram of applying for memory according to an exemplary embodiment of the present invention. Figure 4 As shown, when it is necessary to apply for the use of memory, it is necessary to determine whether the memory priority flag is set. If the memory priority flag is set, the memory is directly applied for and used according to the memory priority flag.

[0055] If the memory priority flag is not set, the memory priority option is obtained, and the memory priority flag is set according to the memory priority option, and memory is applied for and used according to the memory priority flag.

[0056] Figure 5 FIG. 1 shows a schematic diagram of providing a display service according to an exemplary embodiment of the present invention. Figure 5 As shown, when the computing device has not performed a memory test, the preset memory test application is executed after the graphics card driver is initialized, and the above steps S310-S320 are executed to perform the test, obtain the memory preferred option and save it.

[0057] Next, the display server is started. Specifically, the display server can be implemented as a display server, providing display services to clients that send display requests. The display server sets a memory flag based on the memory preference setting. Upon receiving a client's display request, the server selects internal memory or display memory based on the memory preference flag to request memory for display.

[0058] The present invention discloses an image display method suitable for execution in a computing device. The computing device includes a central processing unit (CPU) and an internal memory, and is communicatively connected to a graphics card, wherein the graphics card includes a display memory and a graphics processor. The method includes the following steps: testing a first write speed of the CPU for writing data to the internal memory and a second write speed for writing data to the display memory; testing a first read speed of the graphics processor for reading data from the internal memory and a second read speed for reading data from the display memory; determining a preferred memory option based on the first write speed, the second write speed, the first read speed, and the second read speed, wherein the preferred memory option includes the internal memory or the display memory; upon receiving an image processing request, determining a target memory based on the preferred memory option and storing the image data in the target memory; and obtaining the image data from the target memory by the graphics processor for image display. The present invention can determine the optimal memory based on the write speed of the internal memory to different memories and the read speed of the graphics processor to different memories, thereby improving the image processing capability of the graphics processor and reducing the limitation of the communication connection on the image processing capability.
