We present a low power multimedia SoC with fully programmable 3D graphics, MPEG4 codec, H.264 decoder and JPEG codec for mobile devices. The unified shader in 3D graphics engine provides fully programmable 3D graphics with 35% area and 28% power reduction. Logarithmic lighting engine and the specialized lighting instruction enable 9.1 Mvertices/s vertex throughput. The merged JPEG/MPEG4 codec and the unified shader reduce the silicon area further and the SoC consumes 6.4 mm × 6.4 mm in 0.13 μm CMOS logic process.
