MPRTA: An Efficient Multilevel Parallel Mobile Accelerator for High-Performance Ray Tracing

Ray tracing has been regarded as the future of graphics rendering technology for a long time. However, interactive ray tracing still faces challenges, especially in mobile devices, such as high computational intensity and multiple branches. In this brief, we aim to maximize overall efficiency by leveraging all forms of potential parallelism, including task, basic block, loop, and pipeline levels. We present multilevel parallel ray tracing accelerator (MPRTA), an innovative mobile accelerator that offers high performance and optimal efficiency for ray tracing. Experimental results indicate that MPRTA is 1.67 x more efficient than the currently best-reported mobile accelerator.
