Detailed ways

FIG. 1 shows a schematic diagram of the architecture of a display card applying the method of the present invention, and FIG. 2 shows a flow chart of the method of the present invention. The test method 20 of the present invention can be applied to the display card 10 shown in Figure 1, and the display card 10 preferably possesses 3D (Three-Dimension) image processing capabilities, such as being able to comply with Microsoft's (Microsoft) company's DirectX application program interface , and the Direct3D API. The test method 20 is mainly to check whether the display card 10 can perform normal calculations under higher graphics processing engine (GPU) clock parameters and memory clock parameters, so as to display images normally, especially 3D stereoscopic images normal display. The testing method 20 includes step (201), step (203), step (205) and step (207), which are described below respectively.

Step ( 201 ) is to receive new graphics processing engine (GPU) clock parameters and memory clock parameters for setting the graphics card 20 when it is running. Please refer to FIG. 3 to show the input man-machine interface of the graphics processing engine clock parameter and the memory clock parameter of the present invention. The input man-machine interface 30 can be a window application program executed on a computer, and it displays a picture as shown in FIG. 3 on the display. , through the input interfaces 301 and 303, specify the size and value of the graphics processing engine clock parameter and the size and value of the memory clock parameter.

Step (203) is to use the graphics processing engine clock parameters and memory clock parameters of step (201) to set the display card 10 in a software manner, so that the graphics card 10 is set at the graphics processing engine clock parameters after setting. And operate under the state of memory clock pulse parameter. After using the input man-machine interface 30 to complete the designation of the graphics processing engine clock parameters and the designation of the memory clock parameters, the graphics processing engine 101 is set through the input interface 305, such as the input interface 305 for "test". Operate with the graphics processing engine clock parameter, and set the memory 103 to operate with the memory clock parameter, so that the display card 10 is in the state of the graphics processing engine clock parameter and the memory clock parameter set After the setting is completed, the display card 10 is tested immediately.

Step (205) is to call (Call) the 3D application program interface, so that the display card 10 remains under the window 40 within a predetermined time, executes the display of the stereoscopic image 50, and outputs the stereoscopic image 50 to the display connected to the display card 10, wherein The steps of performing the display of the stereoscopic image 50 include: causing the display card 10 to at least execute a scene lighting (Lighting) command, a model (Create Mesh) command, an object rotation (Object Rotation) command, a sphere map (Spherical Wrap) command and a 3D immediate mode (3D Immediate Mode) command, to display the stereoscopic image 50. Please refer to FIG. 4 to show the test screen diagram of the normal execution of the three-dimensional image of the display card of the overclocking work of the present invention. The specific embodiment of the three-dimensional image 50 in FIG. 4 is a non-stop rotating earth. To be able to normally execute 3D commands such as Lighting, Create Mesh, Object Rotation, Spherical Wrap, and 3D Immediate Mode, Only in this way can the stereoscopic image 50 of the earth be displayed normally on the window 40 . Step (205) executes and displays the execution time of rotating the earth in window 40, which can be completed within a predetermined time such as five seconds, that is, an overclocking test is performed on the display card 10 for five seconds, see the display card 10 Whether the stereoscopic image 50 of the rotating earth can be normally displayed in the window 40 within the five seconds. The consideration of the length of the predetermined time in step (205) is mainly at least the time required to complete the display of the stereoscopic image 50, that is, within the predetermined time, the execution of the scene lighting instruction, model building instruction, object rotation instruction, The stereoscopic image 50 is displayed only by the commands such as the sphere texture command and the 3D immediate mode command.

In addition to allowing the display card 10 to maintain the display of the stereoscopic image 50 under the window 40 within the predetermined time, the above step (205) can be further executed to notify the display card 10 to stop the test immediately. Within the time, the test on the display card 10 is stopped by receiving the “ESC” key press signal of the keyboard.

Step (207) is to judge whether the display shows the normal stereoscopic image 50 in the step (205), if it is true (True), then adopt the drawing processing engine clock pulse parameter and memory clock pulse parameter of step (201) to display card 10 setting , otherwise the display card 10 restores the previously used graphic processing engine clock parameters and memory clock parameters. Please refer to FIG. 5 which shows the test screen diagram of the abnormal execution of the three-dimensional image of the overclocking display card of the present invention. After the execution of the display of the stereoscopic image 50 after a predetermined time, if the screen of the display can still maintain a normal display, then use the input man-machine interface 30 to update the graphics processing engine 101 as the graphics processing engine clock parameter of step (201) to operate , and update the memory 103 to operate with the memory clock parameter of step (201). If the display of the stereoscopic image 50 is performed after a predetermined period of time, if the abnormal situation of FIG. 5 appears on the screen of the display, such as a distorted or speckled screen, it can be known that the overclocking of the display card 10 in the 3D environment will fail, then The display card 10 is restored to the previously used graphics processing engine clock parameters and memory clock parameters, which means that the graphics card 10 cannot be overclocked under the graphics processing engine clock parameters and memory clock parameters in step (201). After the user ends the execution of the window 40 in the fifth figure and the execution of the input man-machine interface 30, the computer will not be unable to continue to operate or crash due to the previous failure of the overclocking of the display card 10, and the computer can still operate normally. .

Further explain the operation of the input man-machine interface 30 in FIG. 3. The tester uses the input interfaces 301 and 303 to designate the engine clock parameters and memory real pulse parameters to be overclocked, and then uses the input interface 305 to perform an overclocking test. If the overclocking is successful , then use the input interface 307 to set the overclocked engine clock parameters and memory real pulse parameters for the display card 10 . The tester can also use the input interface 309 to minimize the entire screen of the input man-machine interface 30 , and can also use the input interface 302 to select the specified option in the option box 306 to perform a file storage operation. The tester can also use the input interface 304 to delete the selection specified in the option box 306. Of course, the option of "default value" is permanently reserved and will not be deleted.

The method 20 of the present invention further provides a dialog man-machine interface 60. The timing of the present invention displaying the dialog man-machine interface 60 can close the window 40 after a predetermined time, and the dialog man-machine interface 60 is used instead to display on the display. Please refer to 6 shows the dialog man-machine interface of the method of the present invention. The main function of the dialog man-machine interface 60 is to allow the tester to confirm whether to change the engine clock parameter and the memory clock parameter of the display card 10 again.

The 3D instruction used in step (205) of the method 20 of the present invention is mainly the basic function that must be used by general 3D game software. Passing the test of the method 20 further provides a positive encouragement for the graphics card 10 to perform overclocking in 3D game software. The method 20 of the present invention further explains the technical reasons why these 3D instructions are selected as the stereoscopic image 50 for display:

1. The scene lighting command is used for lighting. Objects can be seen in the 3D environment because the surface of the object reflects the light from the light source to form an image. At the same time, the light source in the game software is set through different angles to form an image Scene effects, so scene lighting instructions are a very important factor in the entire 3D architecture.

2. The sphere is formed by multiple polygonal meshes, so it is necessary to set the size, shape, and normal vector of the mesh. The basic body structure of the characters or monsters that often appear in 3D game software is formed by the mesh. Grid forming, and the command to create a model is to provide this function.

3. The set object will not move. It is necessary to set the coordinate system and the axis of rotation, and the speed of movement or rotation before the 3D object can be truly activated to produce the effect of movement, such as the character object in the game software To run, it is necessary to move the character model, and the object rotation command provides this function

4. If the object only has a grid, it can only represent the shape and lines of the appearance. It is necessary to map the surface of the object. By establishing the texture coordinates and texture mode, the correct picture will appear on the surface of the object, such as in the game software. Character clothes and armor are done by textures, and the sphere texture command provides this function.

5. Microsoft's Direct3D interface includes a retained mode (Retained Mode) and an immediate mode (Immediate mode). The processing method of the retained mode is a higher-level (Highlevel) part, suitable for beginners. The processing method of the immediate mode is a low-level part, and the design is more complicated, but it has better execution efficiency, and usually the game software is more likely to adopt the processing method of the 3D immediate mode.

The stereoscopic image 50 used in the present invention is mainly a stereoscopic image displayed by executing instructions such as scene lighting instructions, model building instructions, object rotation instructions, sphere texture instructions, and 3D immediate mode instructions. Therefore, the stereoscopic image 50 does not The three-dimensional image 50 is limited to the rotating earth, and the three-dimensional image 50 of other changes, such as characters and three-dimensional figures, as long as the three-dimensional image 50 is displayed through the execution of the above-mentioned commands. The stereoscopic image 50 used in the present invention is preferably a stereoscopic image that is generally familiar to ordinary users and is easy to distinguish between good and bad.

The example of the above-mentioned three-dimensional image 50 of the rotating earth in the present invention, with the hardware capabilities of today's computers, the time required to display the rotating earth can be completed within about half a second, so in order to further understand the overclocking capability of the display card 10 Why, the present invention allows the computer to continue displaying the rotation of the earth within a period of time, such as five seconds. During this period of time, the screen of the display may still maintain a normal display, or the screen of the display may The screen has been abnormally displayed, but in any case, the present invention will not cause the computer to crash (machine) at all, and even in the middle of the test, the present invention can be stopped by receiving the "ESC" key press signal of the keyboard, for example. Tests on graphics card 10. Therefore, the test method 20 of the present invention can be described as a fast, safe, and no-crash test method. At the same time, the tester can easily identify the overclocking capability of the display card 10 with the three-dimensional image 50 of the test result that is clearly and easily discernible. It can be overclocked to that extent.

The method 20 of the present invention can be realized by means of program codes. For example, the method 20 of the present invention is implemented as a test module of a window application program. Execute the test module to pre-test the overclocking capability of the display card 10 .
