Power-Aware 3D Computer Graphics Rendering

Real-time 3D Graphics rendering consumes significant power because of its very high computation and memory access rate. Due to variation in workload and perceptual tolerance, power-awareness can optimize this power consumption significantly, thus facilitating migration to future power-constrained devices such as personal digital assistants (PDAs), tablets, wearables, phones etc. This work proposes such a low power system based on Approximate Graphics Rendering (AGR). The AGR system supports various algorithms and incremental changes to the computational mechanism based on certain pre-specified parameters. The knowledge available apriori about the signal and noise models of graphic images and Human Visual Perception (HVP) are used to select the configuration that meets the quality needs at the lowest power consumption.
