14-1 A 195mW, 9.1MVertices/s Fully Programmable 3D Graphics Processor for Low Power Mobile Devices

A 195mW, 9.1Mvertices/s fully programmable 3D graphics engine is designed and implemented in 0.13μm CMOS process for mobile devices. The power-optimized unified shader architecture provides high performance programmable vertex shading and programmable pixel shading with 35% area and 28% power reduction. The logarithmic lighting engine and specialized lighting instruction improves the vertex throughput to 9.1Mvertices/s including full OpenGL lighting, which is 2.5 times higher performance compared with previous works. The 3D graphics engine was successfully demonstrated on the system evaluation board.
