Abstract
This paper presents a mobile ray tracing processor
(MRTP) with recon figurable stream multi-processors (RSMPs)
for high datapath utilization. The MRTP includes three RSMPs
that operate in multiple instruction multiple d ata (MIMD) mode
asynchronously to exploit instr uction-level parallelism. Each
RSMP is based on single instruction multiple thread (SIMT)
architecture to exploit thread-level paral lelism. An RSMP consists
of twelve scalar processing elements (SPEs) that run multiple
threads in pa
