This paper presents a low power multimedia system-on-chip (SoC) with full integration with fully programmable 3-D graphics, MPEG4 codec, H.264 decoder, and JPEG codec for mobile devices. The mobile unified shader in 3-D graphics engine provides fully programmable 3-D graphics with 35% area and 28% power reduction. Low-power lighting engine which employs logarithmic number datapath and the specialized lighting instruction enable 9.1 Mvertices/s vertex fill rate, which is 2.5 times improvement compared with previous works including transformations and OpenGL lighting. The SoC consumes less than 152 mW for video applications and less than 195 mW for 3-D graphics applications. The mobile unified shader and merged JPEG/MPEG4 codec reduce the silicon area and the SoC consumes 6.4 mm x 6.4 mm in 0.13 mu m complementary metal-oxide-semiconductor (CMOS) logic process.
