Abstract

A method and apparatus for processing pixel rasterization in a 3D rendering processor is disclosed. According to the method and apparatus, the primary depth checking is performed before the performing of the texture mapping, and thus the unnecessary performing of the texture mapping can be removed. Also, the consistency problem can be simply and easily solved using the flag memory, and by performing the depth reading and depth checking twice, the hit rate of the pixel cache memory is heightened. Thus, the method and apparatus is effective in cost, performance, and power consumption.
