Computation-effective 3-D graphics rendering architecture for embedded multimedia system

A new architecture is proposed to realize 3-D graphics rendering for an embedded multimedia system. Because only 20% to 83% triangles in the original 3-D object models are visible by simulation, our architecture is designed to eliminate the redundant operations on invisible triangles without image quality loss. It is based on our index rendering and enhanced deferred lighting approach, and it features a dual pipeline rendering architecture. The simulation and analysis results show that this architecture can save up to 63.4% CPU operations compared with traditional architectures
