支持动态互连结构的模块化多DSP并行处理系统的设计与实现

Design and Implementation of the Modular Multi-DSP Parallel Processing System with Dynamic Interconnection Network

介绍了基于VXI总线的模块化多DSP并行处理系统的构建 ,并着重论述了利用Spar tanII系列FPGA实现多DSP间的高速交叉开关互连网络 ,从而实现了多DSP间互连网络拓朴结构随算法要求而进行的动态编程重构 ,提高了并行处理的效率 ,增大了系统的灵活性、适应性。

This paper introduce a modular multi-DSP parallel processing system based on VXI bus.Emphasize on the implementation of the high-speed crossbar switch network between DSPs on SpartanII FPGA.Crossbar switch can realize the dynamically reconfiguration of the interconnection topology to suit the current algorithm and application.
