Design of a Lighting Engine for Mobile 3D Graphics

모바일 3차원 그래픽을 위한 조명 연산 엔진 설계

We propose an architecture for a lighting engine for mobile 3D graphics. The proposed architecture has a variable pipeline depending on lighting effects and the number of lighting sources so that unnecessary operations and power consumption are minimized. We design a lighting engine basedon the proposed architecture using Verilog-HDL and synthesized it using a 0.25um CMOS standard cell library at 100MHz. The synthesis results show that it occupies 180,000 and 260,000 gates for 24bit and 32bit formats, respectively.
