Abstract:
1. A method of processing pixel rasterization in 3-Dimensional graphic engine, comprising the steps of: (a) receiving a plurality of newly inputted fragment information; (b) checking whether the coordinate of the plurality of newly inputted fragment information are adjacent to the X axis or not; (c) respectively detecting depth values of a plurality of old fragments having the same coordinate value as the coordinate of the plurality of adjacent fragment information from depth cache when the coordinate of the plurality of newly inputted fragment information are adjacent to the X axis; (d) respectively comparing the depth value of the newly inputted fragments with the depth value of the old fragments respectively; (e) respectively storing the depth values of the plurality of the newly inputted fragments in the depth cache respectively when the depth value of the newly inputted fragments are less than the depth values of the old fragments; and (f) respectively performing an alpha blending on the color values of the old fragments and color values of the plurality of newly inputted fragments, after respectively reading out color values of the old fragments from the color cache, and respectively storing color values, which are alpha blended, into a color caches, wherein the 3-Dimensional graphic engine uses a pixel cache and a texture cache that are coupled with a frame memory, and wherein the method is coincidently and individually processed by multiple pipelines that are coupled with the pixel cache and the texture cache per a plurality of newly inputted fragments.
