With the increasing programmability of GPUs (graphics processing units), these units are emerging as an attractive computing platform not only for traditional graphics computation but also for general-purpose computation. In this paper, to study the performance of programmable GPUs, we describe the design and implementation of LU decomposition as an example(More)
This paper presents an efficient parallel algorithm for volume rendering of large-scale datasets. Our algorithm focuses on an optimization technique, namely early ray termination (ERT), which aims to reduce the amount of computation by avoiding enumeration of invisible voxels in the visualizing volume. The novelty of the algorithm is that it incorporates(More)
It is expected that software defined radio (SDR) technology that can access multiple wireless communication systems will be applied to mobile terminals and base stations as a beyond 3G wireless system. An SDR wideband mobile terminal must be capable of high-speed data processing and low power consumption. To evaluate the performance of reconfigurable(More)
Various wireless systems are being developed to meet users' needs, and effective frequency use is urgently needed because of the rapid increase in frequency demand that accompanies the increasing popularity of wireless services. However, general base stations are making no effort to use frequency effectively, and cooperation among wireless system base(More)
