Energy Efficient Data Transmission for Ray Tracing on Mobile Computing Platform

In this paper, we focus the impact of this limitation by analyzing the bandwidth consumption for ray tracing and present energy efficient data transmission method between processor and ray tracing hardware engine. For evaluation of our approach we have implemented a prototype of SGRT system on FPGA. According to our experiment result, our approach shows a 30% reduction of system memory bandwidth on average.
