Description of the invention: [Technical field to which the invention belongs] The present invention relates to the reproduction of a kind of video, and in particular to a two-dimensional graphics decoder including an __no acceleration ship according to a command, and an acceleration map. Model display method and image reproduction. [Prior Art] There is a problem in the video reproduction device, that is, all scenes displayed on the camp screen are represented by day pixels, which places a heavy computing load on the central processing unit (CPU). Therefore, in order to reduce the computation load of the central processing unit, the image reproduction device usually provides a display acceleration function. Graphic ^ Show acceleration Wei Fencheng supports the graphic display processing command, or inserts a hardware circuit into the graphic display processing function to reduce the load of the central processing unit, thereby improving the graphic display processing function. . The main two-dimensional or three-dimensional graphic display acceleration technology used is to improve the performance of the CPU to handle complex graphics and images. These examples include: INTEL's Multimedia Extension (MMX) technology, amd's "3D NOW" technology. In order to perform matrix addition or multiplication more quickly, MMX technology uses a method to improve the processing speed of the CPU, that is, adding a command to the command set of the CPU, thereby providing the function of performing addition or multiplication of multiple registers. This command is called Single Instruction Multiple Date (SIMD). The CPU command set includes multiple SIMD areas. 'FIG. 1A shows a structure of an image reproduction apparatus using a plurality of SIMD commands. 200521885 15202plf Another way to provide graphic display acceleration function is to set the graphic processing function for the hardware circuit of graphic display acceleration to reduce the calculation load of the CPU. Conventional gaming machines with embedded 2D display accelerator chips have an embedded hardware circuit for 1D graphic display acceleration. Since the two-dimensional graphic display accelerator chip handles the graphic display with the embedded graphic display function in the form of a display function, the CPU processing speed in the graphic mode can be greatly improved. FIG. 1B illustrates the structure of an image reproduction device having a two-dimensional pattern display acceleration chip. However, 'accelerated display functions, such as line, polygon, quadrilateral edge and block copy, and the implementation technology for 2D graphics display accelerator chips supported by each graphics card manufacturer are different. In addition, for example, when the graphic display work is not embedded in the graphic display acceleration chip, it is difficult to expect the normal performance of the work by drawing a portrait with a curve. In addition, if the resolution to be performed is different from the resolution supported by the two-dimensional pattern acceleration chip, or if higher resolution is required to represent true color, it is difficult to increase the speed of pattern processing. Another way to provide graphic acceleration is to use a three-dimensional graphic display to accelerate the processing of three-dimensional vector calculations on the wafer, while reducing the CPU's load for displaying three-dimensional geometric calculation processing and rendering processing, as shown in Figure 1C. Using polygons and lines such as circles, rectangles, triangles, and lines as the smallest unit to form a screen, a vector pattern is a pattern represented by a numerical formula, also known as a polygon pattern. In order to express detailed feelings, such as curves and tones, the vector pattern uses various special effects such as rendering, shading, and texturing, and uses a three-dimensional pattern accelerator, 200521885 15202pif to reduce loading. Into subsequent calculations on the CPU. However, if a two-dimensional vector pattern is used in three dimensions, when you want to represent a polygon containing a circle or a curvature environment, you need to use the three-axis view of _ to calculate and fill the texture of the vertices. High-performance graphics processor. < ~ Bao, · said that the graph is different at the same time, "with the familiar home electronics (down = network = technology combination, for example, on the Internet web page dimension to move the day) requires a powerful graphic display function But conventional products, such as digitally reproduced digital discs (Digital Versatile Disc, dvd) reproduced images, have 15 GMIPS (π million age per second), etc. _ CPU 'instead of high-performance _ MIPS Pentium-level cpu, from , Which limits the performance of graphic display processing. In other words, the problem is that only a month & expresses a limited range of graphics, including text or simple images, and it is difficult to achieve two-dimensional vector graphics such as Internet webpages. In addition, even if the conventional two-dimensional graphic display acceleration technology is used, the graphic award 7R accelerator chip also includes complex two-dimensional vector calculations and functions for processing various curves, so that the design of the hardware circuit is very Complex. In addition, due to various problems, such as the limitation of the size of the hardware circuit, the increase in the price of the hardware circuit and peripheral components, the heat generated during operation, and the noise generated by the fan, It is impossible to include all the two-dimensional curve processing functions in one hardware circuit. [Summary of the Invention] The present invention provides a graphic display decoder that includes a graphic display acceleration function according to commands. : T Method for implementing graphic display acceleration function. The function of two-dimensional graphic solution to accelerate the display of the above-mentioned purpose 'The present invention provides a method for converting graphic explicit data conversion step: First, interpret the graphic Data, map data. After the iron, ^ interspersed acceleration command data 'and store the acceleration command pattern coincidence 1 Order at least one of the stored acceleration command data to display / up = speed and display the pattern image In the method of interpreting the pattern data, the acceleration command data is used to speed up the command data, for example, including at least -horizontal scene = 々 or vertical line 1 will make a command to quickly green the screen. In the above-mentioned method of accelerated pattern display, individual software is completed to interpret various data. For example, in the method of “H-type display” and “H-type display”, when it is converted and stored, it is repaired in the pre-stored tree. At least age The speed command is based on the display of the mouth f :! in Shifa. For example, Erlu Wucheng displays the force of the shorthand with a 4 疋 咼 diagram type image. The speed command rarely includes one of the following commands: a command to draw the day element, a command to draw the horizontal line of the garment—a command; a material bit system mapping ^ 521, a horizontal line or a vertical, _ command; drawing using linear =: pattern A command of horizontal or vertical lines; a command of drawing horizontal or vertical lines using a radial gradient shirt-like pattern; a command of repeating a previously completed flat or vertical line edge command, by adding or subtracting), first The horizontal or vertical coordinates ordered by Lai get the coordinate of _ horizontal line or vertical J-line '· -affine transformation command (affine transformation), the size or position of the 7L image eye or gradient_ on the side, as Fill data used in the drawing or-vertical line-command; a color Ϊ = ΐ color conversion) 'to convert the color on the -horizontal line or -vertical line;-branch command to branch to the addition of 在 at the κ site Command the location of talents' and Execute the acceleration command at this address; specify 2, :: to issue -commands that do not have position and hierarchy, and the moving day system is mixed with the graphic image, and specify-commands that specify the background area color other than the moving day zone , Is mixed with the graphic image and displayed, and the color of the moving daytime zone is in the state of / and depending on the flood signal. The unitary single-picture decoder includes-acceleration command conversion and external speed acceleration command conversion unit, which decodes data from and maps data into at least one simplified area. Data 'and store the acceleration command data in a predetermined storage. The oblique two ΓI processing unit is used to execute at least one stored acceleration commander's unpatterned image. Among them, the acceleration command conversion unit and the acceleration command 7 are processed as early as 70. Storage area while operating independently of each other. The interpreting acceleration command conversion unit is, for example, by calling a roofing polygon and converting the pattern data into at least one 200521 & 85 acceleration command # material item. The acceleration command data item is obtained by the turtle performing a scan conversion, and the acceleration command is stored. The storage area of the shape 'where the acceleration command data includes, for example, a horizontal line command and a vertical line drawing command' has been used to quickly draw the graphic image to the $ screen ^ Or in a self-contained graphic tool, the accelerated command conversion unit is executed by, for example, independent software to interpret various graphic data. The 'acceleration command processing unit' in the self-decoder is executed by a unique body circuit, for example, to increase the display speed of the video. In the above-mentioned calcite horse, the external channel includes, for example, a detachable storage medium that can be easily separated from a reproduction device, a human-reproduced storage medium, or a network medium. The invention also provides a reproduction device including a picture decoder. In the reproduction device described above, a graphic image output by the graphic decoder and the audio-video (AV) data read by the channels are decoded and output, which are covered to display an image. Lei = Invented again—a computer-readable recording medium, which is included in the self-supporting system for performing accelerated graphic display methods.

Audio-video data is compressed and encoded according to a standard, such as the Moving Picture Experts Group (MPEG) Graphical data usually refers to: tagged files, such as Hypertext Markup Language (HTML) files; image slot cases, such as Joint Photograp hic Experts Group (JPEG) files and portabie network graphics (PNG) slots; Macromedia's multimedia web authoring software (Flash) files; graphic data such as Java programming language (Java) and fonts Data. The input control unit 213 loads audio-video data or graphic data into their respective memories' and processes them separately. If audio-video data and graphic data are multiplexed into one file, demultiplexing may be included Multiple functions. The memories 220, 222, and 224 include a first memory 220, a second memory 222, and a third memory 224. The first memory 220 is stored by the reading units 210, 212, and inputs. The control unit 213 buffers the audio-video data read from the external channel. The second memory 222 stores the pattern data read from the external channel. The third memory 224 is a two-dimensional graphics decoder. The memory used by 200 will be explained later, and the pattern display acceleration command and filling data are obtained by converting the pattern data. According to the intention of the designer, the first to third memories 220 to 224 It can be used as an individual memory, and a memory can be divided into its own memory by dividing the address 13 200521885 15202plf 220 to 224 for execution. The frequency video decoder 240 will store the audio in the first memory 2220. A video data is decoded and displayed. The one-dimensional graphic decoder 200 includes a graphic data presentation engine 25 and a two-dimensional graphic display acceleration command processing unit 252. Graphic data expression bow engine 250 is used to interpret the read graphic data and convert it into graphic display acceleration command and fill data, and store the command and data in the third memory 224. The graphic representation engine 25 is better performed by software running in the CPU, so that various types of graphic data can be interpreted flexibly. Hereinafter, the graphic presentation engine 250 will be referred to as a presentation engine. The two-dimensional pattern display acceleration command processor 252 executes the pattern display acceleration command and the filling data stored in the memory 224, and displays the two-dimensional pattern.

Seven frame buffer memories 260 store the moving day output from the audio-video decoder and the two-dimensional graphic image output from the two-dimensional graphic decoder 200: The present invention mixes the moving day and the graphic image, and The mixed number is converted into an analog signal by a digital analog converter and displayed on the screen. Therefore, an image reproduction device such as a DVD or DTV can provide = interactive content. It is an animation and related two-dimensional graphics Images are displayed on the screen together. If you are using a conventional one-dimensional graphic display accelerator, you must interpret the text or table information contained in the above graphic data, such as marked ^ files, 14 200521 and convert it into display functions such as lines, Quadrilateral, circular, which can be processed by a two-dimensional graphic display accelerator. In addition, the conventional two-dimensional graphic display accelerator also includes a function of outputting a bitmap from a JPEG file or a PNG file, and a function of processing curves, lines, and polygons of a Java or Flash file. Therefore, the hardware structure of the conventional two-dimensional graphic display accelerator becomes complicated. However, the two-dimensional graphic decoder 200 of the present invention can more simply perform the graphic display acceleration function by using a horizontal line or a vertical line drawing command as a graphic display acceleration command. Among them, the horizontal or vertical line drawing command will be explained later. The two-dimensional pattern decoder 200 of the present invention will be explained in more detail below.

Secondly, in order to display the selected page on the screen by the acceleration command processing unit 252, the selected page is set to page display memory, 'crying (PAGE—DISPLAY) This series of processes is called the page setup process. At the same time, the lock unit 410 included in the display acceleration command processing unit 252 reads the register value set by the aforementioned performance engine 25 and selects the page to be displayed ' And read the _display acceleration command data from the third clock, which is the page corresponding to the selected th. The graphic command decoder 42 included in the display acceleration command processing unit 252 interprets and reads it out.
