Abstract

A high quality and performance 3D graphics architecture (101) suitable for portable handheld devices is provided (100). The 3D graphics architecture incorporates a module to classify polygons by size and other characteristics. In general, small and well-behaved triangles (400) can be processed using 'lower-precision' units with power efficient circuitry without any quality and performance sacrifice (e.g., realism, resolution, etc.). By classifying the primitives and selecting the more power-efficient processing unit to process the primitive, power consumption can be reduced without quality and performance sacrifice.
