Abstract

Chia-Ming Chang, Shan-Yi C huang, Liang-Gee Chen , Fellow, IEEE,a n d S h a o - Y iC h i e n, Member , IEEE Abstract—Intensive pixel shading dom inates the power dissipa- tion of the graphics pipeline as the screen resolution grows. In this work, we propose a 130.3 mW 16-core mobile GPU with three pixel approximation techniques and a corr esponding tile-based rasteri- zation architecture. The proposed architecture can trade-off be- tween power consumption and visual quality to provide power- aw
