In this paper, we focus the impact of a memory bandwidth limitation by analyzing the bandwidth consumption for ray tracing system and present an energy efficient data transmission method between processor and ray tracing hardware engine. For evaluation of our approach, we have implemented a prototype of ray tracing architecture using our approach on FPGA platform. According to our experiment result, our approach shows a 48% reduction of system memory bandwidth on average.
