Graphics primitive preprocessing method, graphics primitive processing method, graphic processing method, processor and device

Abstract

The invention provides a graphics primitive preprocessing method, a graphics primitive processing method, a graphic processing method, a graphics primitive preprocessor, a graphics primitive processor and a graphic processing device. The graphics primitive preprocessing method comprises the following steps: simulating the actual output process of a graphics primitive, acquiring index values of all peaks of the graphics primitive during cache, acquiring a peak index sequence table through reordering, and giving the amount of peaks of the graphics primitive to be substituted. The graphics primitive processing method comprises the step of outputting the graphics primitive and substituting the peak data during cache. The graphic processing method comprises the step of processing all graphics primitives in sequence by the graphics primitive processing method in the order of graphics primitive strings. The graphics primitive preprocessor comprises a simulating unit, an index value unit, a reordering unit and a peak amount unit. The graphics primitive processor comprises an output unit and a substituting unit. The graphic processing device comprises a reception unit, a graphics primitive preprocessor and a graphics primitive processor. According to the invention, a traditional cache mark is not required, so that the area of a chip is saved, and the design complexity and power consumption of the chip are reduced as well.

Description

technical field [0001] The present invention relates to graphics processing, in particular to a graphics element preprocessing method and processing method, a graphics processing, a graphics element preprocessor and a processor, and a graphics processing device. Background technique [0002] Today's users have higher and higher requirements for visual effects of computer applications, especially game applications, which often need to draw complex and exquisite graphics, and only one scene often involves a large number of graphics. This will inevitably bring a large number of uninterrupted graphics operations, and accordingly, the requirements for the computing capabilities of graphics processing chips are getting higher and higher. [0003] In the prior art, primitives are used as the basic unit of graphics drawing. Each primitive contains one or more vertices. For example: a point primitive is one vertex, a line segment primitive contains two vertices, a triangle primitiv...
