This paper presents a reconfigurable mobile stream processor for ray tracing. The processor is implemented with 16mm2 area in 0.13μm CMOS technology. The processor adopts a single instruction, multiple thread (SIMT) architecture in order to exploits instruction-level and thread-level parallelism. The SIMT architecture consists of 12 stream processors (SPs). A low hardware utilization caused by a branch...
In this paper, we propose a clipping engine (CE) in 3D graphics. A conventional CE shows lower performance as clipping-ratio increases, because the process time of a clipped triangle is much longer than that of a non-clipped triangle. We focus on conserving performance, while clipping-ratio changes. Proposed architecture separates datapath into clip datapath and perspective division & viewport...
