A 210mW graphics LSI implementing full 3D pipeline with 264Mtexels/s texturing for mobile multimedia applications

A 121 mm/sup 2/ graphics LSI is for portable 2D/3D graphics and MPEG4 applications. The LSI contains a RISC processor with MAC, a 3D rendering engine, 29Mb DRAM and is built in a 0.16/spl mu/m pure DRAM technology. Programmable clocking allows the LSI to operate in several power modes for various applications. In lower cost mode, power consumption is under 210mW, delivering 264M texture mapped pixels per second.
