Selecting the Optimal Tile Size for Low-Power Tile-Based Rendering
نویسندگان
چکیده
Power-aware graphics architectures are receiving more attention recently. In this paper we analyze rendering techniques suitable for low power devices. One technique that looks promising is Tile Rendering. This technique decomposes a scene into tiles and renders each tile independently. For several scenes we compute a tile size that allows most triangles to be rendered without being divided into subtriangles. It is also shown that this technique reduces the bandwidth requirements substantially. Furthermore, different methods for approximating the data traffic to and from a graphics rasterizer are presented. Keywords—graphics architecture, tile based rendering.

Efficient State Management for Tile-Based 3D Graphics Architectures
Tile-based rendering is a promising technique for low-power, 3D graphics platforms. This technique decomposes a scene into smaller regions called tiles and renders the tiles one-by-one. The advantage of this scheme is that a small memory integrated on the graphics accelerator can be used to store the color components and z (depth) values of one tile, so that accesses to these values are local, ...
متن کاملSuitability of tile-based rendering for low-power 3d graphics accelerators
I n this dissertation, we address low-power high performance 3D graphics accelerator architectures. The purpose of these accelerators is to relieve the burden of graphical computations from the main processor and also to achieve a better energy efficiency than can be achieved by executing these computations on the main processor. Since external data traffic is a major source of power consumptio...
متن کاملMemory Bandwidth Requirements of Tile-Based Rendering
Because mobile phones are omnipresent and equipped with displays, they are attractive platforms for rendering 3D images. However, because they are powered by batteries, a graphics accelerator for mobile phones should dissipate as little energy as possible. Since external memory accesses consume a significant amount of power, techniques that reduce the amount of external data traffic also reduce...
متن کاملIrregular Morphing for Real-Time Rendering of Large Terrain
The following paper proposes an alternative approach to the real-time adaptive triangulation problem. A new region-based multiresolution approach for terrain rendering is described which improves on-the-fly the distribution of the density of triangles inside the tile after selecting appropriate Level-Of-Detail by an adaptive sampling. This proposed approach organizes the heightmap into a QuadTr...
متن کاملUsing Application Bisection Bandwidth to Guide Tile Size Selection for the Synchroscalar Tile-Based Architecture
This paper investigates the impact of proper tile size selection on the power the power consumption for tile-based processors. We refer to this investigation as a tile granularity study. This is accomplished by distilling the architectural cost of tiles with different computational widths into a system metric we call the Granularity Indicator (GI). The GI is then compared against the bisection ...
