Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a process of a web browser according to an embodiment of the present invention.

When a user enters a web URL through a web browser, the web browser connects to the web server via HTTP through a cellular phone communication network. Then, the web server downloads the html of the web page of the URL, and the web browser receives it and parses it. Then, the layout of the screen page is formed and the screen layout of each item is determined.

By allocating the off-screen memory of the web page size, the content of the layout is first painted on the off-screen using shapes, and in the case of text, the characters are displayed in fonts, and in the case of images, the bitmap is displayed on the screen. Mark with.

After drawing the contents of the web page on the off-screen, the partial screen is displayed on the LCD according to the LCD screen size of the entire web page. Afterwards, when the user scrolls, only the right screen is displayed on the LCD.

2 is a block diagram illustrating a browser acceleration element of a graphics processing apparatus according to an embodiment of the present invention.

An item that may be accelerated by the graphic processing device during the operation of the web browser is a display process of the web browser screen. That is, as shown in FIG. 2, among a web browser display through a graphic processing apparatus, a polygon display, a text display, an image display, and a partial screen display may be used. Can be divided into acceleration elements and accelerated.

In the polygon display, which draws the screen layout, the drawing can be accelerated by using the graphic processing unit.

According to an embodiment of the present invention, a web browser acceleration system using a graphics processing apparatus in a mobile terminal includes: a graphics processing unit (Graphic Processing Units: GPU); And a mobile terminal including a web browser.

The web browser receives the html of the web page from the web server and displays the web page according to the html. In particular, the web browser according to the embodiment of the present invention receives the html from the web server, and if the html includes a polygon (polygon), and transmits a polycon display acceleration command for drawing the polygon to the graphics processing apparatus.

In a web browser, drawing using shapes corresponds to clearing the entire screen, border, or outline. The drawing of the figure mainly includes a background drawing, a table box drawing, and the like. In fact, the graphics API used to draw it is called 'DrawRectangle', and drawing of a Rectangle is a function that is commonly found in graphic processing devices. Therefore, when the graphic drawing is processed by the graphic processing unit, the acceleration effect is great. Although it is different for each graphic chip, drawing of this figure can be implemented in a 3D graphic chip or by using 2D dedicated instructions.

In this case, the drawing may be accelerated by 4 to 8 times when drawing using a 3D graphic module, and may be accelerated by about 10 to 50 times when drawing using a 2D graphic module.

3 is a block diagram illustrating a web browser text display acceleration method of a graphic processing apparatus according to an embodiment of the present invention.

In the case of text, the font can be pre-loaded into the graphic processing device and drawn using the software, rather than drawing in software (S / W).

According to another embodiment of the present invention, a web browser acceleration system using a graphics processing apparatus in a mobile terminal, the graphics processing unit (Graphic Processing Units: GPU); And a mobile terminal including a web browser.

The web browser receives the html of the web page from the web server and displays the web page according to the html. In particular, the web browser according to the embodiment of the present invention receives the html from the web server, and if the html includes the text (text), and transmits a text display acceleration command for drawing the text (graphic) to the graphics processing apparatus.

In the case of a mobile terminal, drawing a vector font is considerably slower, so the font is often stored separately by size rather than this method. In general, if the graphics processing device has an acceleration function for vector fonts, the vector fonts can be directly drawn. If not, the fonts are drawn by the font size by size.

The suggested method is to classify vector fonts by size and to use alpha channel for letter shapes. The reason for using the alpha channel is to soften the outline of the text using anti-aliasing.

According to an embodiment of the present invention, first, according to a font for displaying text, the mobile terminal performs a step of storing or loading a character set composed of characters to which the font is applied in the memory of the graphic processing apparatus for each font.

Next, the mobile terminal determines whether the text characters included in the text to be displayed through the web browser are stored in the memory of the graphic processing apparatus.

Next, when the text characters are stored in the memory of the graphic processing apparatus, the text is displayed using the character set stored in the memory of the graphics processing apparatus.

If necessary, the character set stored for each font is preloaded to be cached and reused later. In the case of the character set cache stored for each font, a limit is placed on the memory at the same time, and this caches the character set stored for each font by the LRU (Least recently used) algorithm.

In addition, the character set stored for each font should be preloaded into the stack memory used by the graphic processing apparatus. In order for the graphic processing unit to use the character set stored for each font, the character set in the host must be loaded into the dedicated stack memory in advance.

Then we load the shape of the font glyph (alpha channel) for each character, holding the shape of the RGBA.

After the font-specific character set is loaded, the characters are drawn. Text is colored in the corresponding text area to specify the color and the text area is drawn with the Alpha channel in the desired location. When all the letters are drawn, the letters are displayed on the LCD screen.

Later, in the case of drawing the characters of the same font, the process of saving or loading the character set for each font is omitted, and only the process of drawing the characters after the coloring and displaying them on the screen can improve the processing speed.

This also varies from graphic chip to chip, but the image and the alpha channel can be drawn on a 3D graphics chip or a 2D dedicated command. In this case, when drawing with 3D graphics module, it will be accelerated by 5 ~ 10 times, and when drawing with 2D graphics module, it is expected to be very fast about 40 ~ 80 times.

In the case of a web page, a lot of images are included in addition to text. If such an image is loaded into the graphic processing apparatus and then drawn in the graphic processing apparatus, the processing speed may be greatly improved.

According to another embodiment of the present invention, a web browser acceleration system using a graphics processing apparatus in a mobile terminal, the graphics processing unit (Graphic Processing Units: GPU); And a mobile terminal including a web browser.

The web browser receives the html of the web page from the web server and displays the web page according to the html. In particular, the web browser according to an embodiment of the present invention receives the html from the web server, and if the html includes an image, and transmits an imagen display acceleration command for drawing the image to the graphics processing apparatus.

In a web browser, all pictures are displayed on the web screen using images. Icons such as menus mainly use images in GIF format, and in the case of high quality images, such as photos, images in JPG format are used.

In order to draw through a graphics processor, this image must be converted to RGB format. If there is a decoder of GIF / JPG in the graphics processing apparatus, it is converted into RGB format using the decoder. Otherwise, it is decoded into S / W and converted into RGB format.

Then, after loading the image into stack memory in the graphics processing unit, the image is drawn in the step of drawing a web page.

This also varies from graphic chip to chip, but the 3D graphics chip can be used to draw images and alpha channels, or can be drawn using 2D-specific commands. Generally, the 3D graphics module includes a function of drawing by image scaling, but the 2D graphics module may not include such a function. In this case, when drawing with 3D graphics module, it will be accelerated by 5 ~ 10 times, and when drawing with 2D graphics module, it is expected to be very fast about 40 ~ 80 times.

Meanwhile, according to another exemplary embodiment of the present invention, a part of the web page displayed through the web browser can be enlarged. To this end, first, the web browser may perform the step of displaying the first area of the entire web page.

Next, the web browser may designate a predetermined area of the first area as the second area and receive an enlargement command for the second area.

Next, the web browser may perform the step of displaying a temporary enlarged screen in which the second area of the first area of the web page is enlarged to the full screen.

Finally, the graphic processing apparatus may complete the drawing process for the second area to generate a detailed enlarged screen and replace the temporary enlarged screen with the detailed enlarged screen.

Also, when drawing the contents of off-screen web pages into the LCD buffer, letting the software copy the contents of the memory rather than copying the contents of the memory is much faster without the CPU load, which is advantageous for multitasking.

If you have drawn the contents of a web page on the off-screen, you should display it on the LCD screen. In general, web pages are many times larger than LCD screens, so some of the off-screen web screens must be moved to the LCD screen frame buffer.

At this time, it is slow to copy memory by S / W method and slow when user scrolls web page.

So this also requires acceleration of the graphics processor.

This is expected to be about 10 to 40 times faster in H / W acceleration than S / W.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications, changes, etc. fall within the scope of the claims Should be seen.
