Abstract: PURPOSE: A system and a method for processing mapping of a three-dimensional rendering processor are provided to improve performance of bump mapping and environment mapping by sharing a cache memory. CONSTITUTION: A system for processing mapping of a three-dimensional rendering processor includes a level information calculator(11) for calculating a distance level of information of one of texture mapping, bump mapping and environment mapping applied from the outside, an address generator(12) for calculating a map address of the external mapping information corresponding to the distance level, and a cache memory(13) storing inner mapping information corresponding to the texture mapping, bump mapping and environment mapping. The system further includes an interpolator(14) for interpolating the inner mapping information read from the cache memory, a normal vector transformer(15) for transforming normal vector of the bump mapping information according to the interpolated inner mapping information, an illumination computation unit(16) for computing an illumination value of the bump mapping information, and a color mixer(17) for mapping a color value corresponding to one of the texture mapping, bump mapping and environment mapping information.
