Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] In the embodiment of the present invention, straight lines and flat-bottomed trapezoids are selected as basic graphics, and vector graphics are decomposed into basic graphics composed of flat-bottomed trapezoids or straight lines, which are sent to hardware acceleration logic processing, which can simplify hardware acceleration logic and improve processing efficiency.

[0040] In the basic graphics selected in the embodiment of the present invention, the slope of the straight line can vary in a wide range. As long as the starting point and slope of the straight line are known, the hardware ac...

Abstract

The invention is applicable to multimedia data processing field, which provides a vector graph accelerating method and a multimedia player. The method comprises the following steps: decomposing the vector graph into basic graphs formed by flat-bottom trapezoids or straight lines; and transmitting the decomposing result of the vector graph to a hardware accelerating logic for processing. The invention allows the basic graphs processed by a graph accelerator to be standard, simple and convenient for hardware design and implementation through decomposing the vector graph into combinations with the flat-bottom trapezoids or straight lines as the basic graphs, thus promoting acceleration performance, reducing power consumption of products and shortening the development cycle of products.

Description

technical field [0001] The invention belongs to the field of multimedia data processing, in particular to a vector graphics acceleration method and a multimedia player. Background technique [0002] In the computer field, an image has two representations: raster graphics (Raster Graphics) and vector graphics (Vector Graphics). Raster graphics use bitmaps (Bitmap) to describe a scene, which is highly dependent on the resolution of the display device. The use of vector graphics can overcome the dependence of raster graphics on the resolution of display devices, and is widely used in Flash animation playback, Global Positioning System (Global Positioning System, GPS) image processing, etc. [0003] A two-dimensional vector graphic can be composed of points, straight lines, curves, or closed geometric regions surrounded by polygons and curves. Areas can be filled in different ways, such as with a single color or with a bitmap. Filling generally adopts the scan line model, fro...
