Abstract :
This paper presents a power-aware dynamically reconfigurable rendering engine design, which changes power as rendering throughput and image quality change. At algorithm level, a precision-aware shading scheme is proposed to improve the power efficiency of the conventional shading algorithm through the combination of precision detection and fraction masking techniques. At architecture level, a processing element (PE) based scalable architecture is combined with dynamic task scheduling and dispatching techniques to raise hardware utilization rate and reduce computation latency. Finally a prototyping design which delivers 453MPixels/s, 16.4MTriangles/s, 2.24MPixel/mJ is presented
