Abstract

MorphoSys is a reconfigurable SIMD architecture. In this paper, a BSP-based ray tracing is gracefully mapped onto MorphoSys. The mapping highly exploits ray-tracing parallelism. A straightforward mechanism is used to handle irregularity among parallel rays in BSP. To support this mechanism, a special data structure is established, in which no intermediate data has to be saved. Moreover, optimizations such as object reordering and merging are facilitated. Data starvation is avoided by overlapping data transfer with intensive computation so that applications with different complexity can be managed efficiently. Since MorphoSys is small in size and power efficient, we demonstrate that MorphoSys is an economic platform for 3D animation applications on portable devices.
