开放式大规模阵列处理系统多核DSP矩阵设计

摘要

To meet the increasing requirements for high processing speed and I/O bandwidth of large-scale array signal processing systems,a multicore DSP matrix can be built based on VPX (VITA46) architectures.In this matrix,several basic processing element modules are connected through high-speed serial RapidIO switches to construct a required system topology structure.Combined with RapidIO communication middleware and customized DSP bootloading techniques,a multicore DSP matrix becomes into high performance and a loosely coupled parallel processing system with high performance is realized.This processing array has open architecture,supports the insertion of new tasks and up-to-date techniques,and can satisfy upgrading system requirements during the whole product life cycle.The multicore DSP matrix has been used in several avionics projects and provided strong support for system iterations and evolvements.%为了满足大规模阵列处理系统对运算处理速度和总线带宽日益增长的需求,基于VPX(VITA46)架构构建了一种多核DSP矩阵,其中若干个基本处理单元模块经由高速串行总线开关联结形成所需的系统拓扑结构,并结合通信中间件技术和DSP自定义自举加载技术来实现高性能的松耦合并行处理系统.这种处理阵列具有开放式体系结构,支持新任务、新技术的插入,可在系统全寿命周期内响应不断扩展的外部需求.目前多核DSP矩阵已在航空电子领域多个工程项目中得到应用,为系统的滚动迭代发展奠定了坚实基础.
