A light-reflected computer graphics shading circuit has been developed to be used as computer graphics processor in PCs and workstations. Its hardware implementation in ASIC of Phong shader, bump-mapping, and sinc filter for texture mapping may be the first such technology in this field. A chip can simultaneously draw four million vectors (10-pixel arbitrary slopes)/s. and render 1.2 million polygons (100-pixel 3-D triangles)/s. while applying Phong shading, bump and texture mapping, and hidden surface removal in a frame buffer system, implemented as a single-port DRAM. 940,000 gate CMOS with 0.3 $\mu$m CMOS rules in a TCP package is used.
