A 3D graphics pipeline has geometry operations for computing the attributes of vertices of polygons, and rendering operations for filling colors inside the polygons. The geometry operation is computation-intensive, and the rendering operation is data-intensive as well computation-intensive. To relieve bottlenecks, 3D graphics hardware has been evolving using fast, parallel datapaths such as multicore vector processors with 3D graphics-optimized memory systems. This chapter imparts an understanding of various low-power techniques for mobile applications. It discusses low-power architectures related to a real-time rendering system. Then, low-power techniques for vertex shaders and pixel shaders are described. The chapter provides an overview of a mobile unified shader, focusing on the differences from PC or console systems. Among the IPs in a mobile multimedia system-on-a-chip (SoC), the 3D graphics processor is one of the biggest bandwidth consumers owing to the large data requirements for vertex, texture, color and depth.
