Low Power Arithmetic Unit for 3D Graphics Applications

Abstract

Graphical processing units (GPUs) have wide variety of applications in different fields such as compute art, engineering, science, medicine, entertainment, advertising, visualization, military, and graphical user interface. The growth in the GPUs applications has led to evolution in the hardware design to handle the needed increase in performance. Also, the fast growth of the mobile electronics market and the transition from text based applications to versatile multimedia applications resulted in increasing the popularity of mobile communication devices. Real-time 3D graphics are becoming one of the greatest interesting applications in mobile workstations due to their benefits for gaming, advertising, marketing, and avatar. GPUs are mainly composed of several unified shaders. Each unified shader contains general purpose arithmetic unit and special function units (SFUs) that are used for computing special
