Abstract :
We present a 152 mW multimedia SoC with MPEG4 codec, H.264 decoder, JPEG codec and fully programmable 3D graphics for mobile applications. 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 give 9.1Mvertices/s vertex fill rate. The merged JPEG/MPEG4 codec and the unified shader reduce the silicon area further and the SoC consumes 6.4 mm times 6.4 mm in 0.13 mum CMOS logic process.
