| dc.description.abstract | Ray-tracing and radiosity algorithms can produce very realistic images, but they require a lot of computations which make them impractical for scenes of highcomplexity. Several attempts have been made to speed up computations through parallel processing. To get orders of magnitude speedup, massive parallelism involving multiplestreams will be necessary. In this paper, a parallel-pipelined multiprocessor system is described, which is made of clusters of specialized computing modules, each constructed of aDIntersection Computation Unit (lCU) and a number of Cell Traversal Units (CTUs). Both ICU and CTU are of type pipeline and with data-driven execution. A pseudo-dynamicscheduling is used to reconfigure the system at run time so that the workloads distributed over clusters can be more or less balanced. Furthermore, a hierarchical memory structure is proposed to reduce the average loading time of patches. Performance evaluation has been done and 15% more speedup can be obtained as observed by queueing networksimulation. A complete system level simulation is under way by using BONeS which is ablock oriented network simulator. | en_US |
