Similarly, the number of common displays 12, such as liquid crystal display points, is referred to as the resolution of the display. However, the resolution of the internal frame buffer (Frame Buffer) and the external display is not necessarily the same, and the resolution of the frame buffer (FrameBuffer) is smaller than the resolution of the display 12, for example, The frame buffer 10 has a resolution of 1 〇 24×768, and the display 12 has a resolution of 1280×1024. In order to match the resolution of the display 12, the drawing chip module n must be output to the display 12 according to the (?) timing control data corresponding to the ratio of the frame buffer of the 200832275 (Frame Buffer) 10 and the display 12 resolution. .

The above timing control data is captured in the design edge chip module (1), and the designer must fine-tune the different timing control materials by the resolution of each surface display, 1; 2 or other requirements. As for the timing table for recording the complex array timing control data, it is stored in the display interface basic input/output system 19 (referred to as VGA BI0S) to support the needs of liquid crystal displays 12 of various sizes. The display interface basic wheel input/output system (VGA BIOS) 19 can exist in a stand-alone chip mode or integrated into the system's basic input/output system (SyStem bios) (not shown). Therefore, the number of sets of data in the timing table represents the number of types of displays that the graphics die module 11 can support, and this correspondence will cause serious problems on the television display.

According to the above concept, the "two-party brother: map, the punch is the The computer system is originally based on the above concept, and the second-degree spatial image processing material according to the present invention is based on the description of the new signal to form a second image. In the second frame buffer, θ and the second frame are written. [Embodiment] Please see the second figure, which is the method for improving the conventional methods of the present invention. In the second and second systems, the function of the green chip chip module is as follows. The picture can be stored in the module 21, or it can be combined in the north bridge chip (not shown). The module 21 is mainly stored in the pixel-level color value of the first frame in the original frame buffer (Fr test) 20 of the computer system 2, 8 200832275, and then the edge wafer module 21 is utilized. The three-dimensional spatial image processing engine 210 has an image resolution amplification of the first frame/ Small processing forms a second frame 'and then writes the frame to an additional second frame buffer 29, and finally corresponds to the basic input/output system 28 stored in the display interface. The display 22 controls the data to output the second frame to the display 22 for display.
舉例來說，原始之第一圖框缓衝器（Frame；Buffer)2〇 之解析度為1280X1024，而顯示器22的解析度為 1024X768，所以繪圖晶片模組21會將原始之第一圖框緩 衝器（Frame Buffer> 20中解析度為1280x1024之第一圖 框之像素點色彩值讀出，然後利用該緣圖晶片模組21中具 有之三度空間影像處理引擎210來對該第一圖框進行一影 像解析度縮小處理而形成解析度為1024X768之第二圖 框，然後再將該第二圖框寫入—第二圖框緩衝器29中，最 後^根據存放在顯示介面基本輸人/輪“統28中對應於 義不器22之料序控織料來將該第二圖框輸出至顯 不器22來進行顯示。 、 八丨叹別你始之第一圖框緩衝器（FrameBuffer) 析度為/卿X12GG，而例如以液晶顯示器完成之顯 1024x768 為雜刪1==咖Β秦）2G帽析度 妙像素點色彩值讀出，然後利用 二；：：:且1中具有之三度空間影像處理引擎21〇 弟I框進行—影像解析度縮小處理而形成解析度 9 200832275 為=6::第二圖框，然後再將該第二圖框寫入一第 基本輸入 該第二圖框輸序㈣資料來將 僅利二不增加硬體成本的前提下，綱 利用該、.，』4她21中縣就具有之三度For example, the original first frame buffer (Frame; Buffer) has a resolution of 1280×1024, and the display 22 has a resolution of 1024×768, so the drawing chip module 21 buffers the original first frame. The pixel value of the first frame of the resolution of 1280×1024 is read out in Frame Buffer<20>, and then the first frame is obtained by using the three-dimensional spatial image processing engine 210 in the edge image chip module 21. Performing a resolution reduction process to form a second frame having a resolution of 1024×768, and then writing the second frame into the second frame buffer 29, and finally according to the basic input in the display interface/ The wheel "corresponding to the material control fabric of the device 28 to output the second frame to the display 22 for display."

The second frame stored in the second frame buffer 29. Even in order to satisfy the same resolution, the television 24 with a large visible area and a small number of accesses does not have to be used as a means to store multiple sets of timing control data. The third space image processing engine 210 is used to generate a second frame with slight changes in resolution to achieve the requirement of responding to the change of the visible area of the television 24. In addition, please refer to the second and third figures, where the third picture is A flow chart of a method for controlling a three-dimensional spatial image processing engine 210 for image resolution processing. First, step 31 indicates that the system provides a render timer, and the render timer is timed. An update signal is sent, and then step 32 indicates that the system further defines the second frame buffer 29 in the image-specific memory space, and then Step 33 indicates that the system displays the display starting address to capture the original starting address (for example, the starting address of the first frame buffer 20) and the second just defined. The start address of the frame buffer 29, so that the drawing chip module 21 reads the image from the second frame buffer 29 and performs the display operation of the back end. The size of the frame buffer! 29 can be an integer multiple of the second frame, such as double, double, etc., but if the second frame buffer, 29 is just the size of the second frame, the three-dimensional image The processing engine 21〇 can't achieve the highest efficiency, and it may cause the data display to be not smooth enough. Therefore, using the double or double buffer of 200832275 can make the three-dimensional image processing engine 210 fully efficient. The smoothness of the face display. Step 34 indicates that the three-dimensional spatial image processing engine 210 triggers the update signal according to the render timer, and uses the texture processing program to reduce the size of the page (戋* zoom in) Processing, and writing the processed second frame to the second frame buffer 29, which can be regarded as a texture buffer. In this way, you can complete the screen resolution adjustment and use the second frame to cry * 29 for display purposes. ^ Further, step 35 shows that if the display mode remains unchanged, the operation of step 34 is continued, but if the display mode is changed, the inner valley shown in the step is performed. (1) The second frame buffer 29 is The memory space is released; (7) reloading the display start address (display gamma _ job), and then through step 37 to determine whether the driver is finished, and when the driver is not finished, return to step 32 to proceed. The second frame buffer 4 is reset to 10 '(4) to meet the user's demand for different resolutions. In this way, the present invention can support a plurality of display modes by using the finite (four) sequence control (4) through the adjustment box setting of the second frame buffer 29. Thus, it is possible to effectively improve the missing means, thereby achieving the hair, county The main purpose of the invention.
