摘　　要：随着各种测试系统性能的不断提高,对系统内数字信号处理能力的要求也越来越高。为满足日益增长的处理性能的要求,设计了基于VXI总线的并行DSP模块,集成了4片高端浮点DSP芯片,并通过增加高性能管理单元、优化DSP簇拓扑结构、增强DSP簇数据缓存能力、扩展PMC通用接口等技术手段,使模块具备了强大的信号处理能力和灵活的应用开发方式。该模块为VXI总线接口,可应用于高性能雷达信号处理以及高速控制系统。Along with the continuous improvement of the performance of various testing systems, the requirements for the intra-system digital signal processing ability are higher and higher. In order to meet the increasing demands for the performance, this paper designs the parallel DSP module based on VXI bus, integrates four pieces of high-end floating-point DSP chip, and through the technical means such as increasing high-performance management units, optimizing DSP cluster’s topological structure, strengthening DSP cluster’s data cache capacity, and expanding PMC common interface, etc., makes the modules possess strong capacity of signal processing and flexible way of application development. The module, which has VXI bus interface, can be used in high performance radar signal processing and high-speed control system.
