基于CPCI总线的多DSP处理模块的设计及实现

超高压直流输电控制保护系统硬件平台的开发,目前面临着巨大的挑战,主要表现在:直流输电测控点多,数据运算量大,系统规模和复杂度不断增加,单CPU的运行已很难胜任工作。结合灵宝、贵广二回工程,在深入分析超高压直流输电控制保护系统的发展和现状,参考其他领域特别是通信和计算机技术发展的基础上,开发了一种实用于超高压直流系统的新型DSP模块。该模块采用64位,66MHz的CPCI总线作为外部总线接口,标准的6U板型,8片DSP芯片TS201S构成多DSP并行处理结构,具有实时运算能力强、接口灵活、可扩展性和通用性强等特点。经过测试和现场应用,各项技术指标良好,运行稳定可靠,能够满足超高压直流输电的应用。

Design and implementation of multi-DSP module based on CPCI bus

The UHVDC control and protection system in a hardware platform development is faced with a great challenge,including numerous HVDC control points,the data processing capacity,increasing complexity of the system,single CPU can't meet the requirements.Combining with our LingBao and GuiGuang projects,this paper deeply analyzes the development of HVDC Control and Protection System.Based on the development of communication and computer technology,it develops a new DSP module that is practical in HVDC system.This module packs the parallel processing power of eight TS201S DSPs and the speed of a 64-bit,66MHz PCI external bus interface on a 6U Compact PCI board,which has many excellent characteristics,such as real-time computation ability,flexibly interface and scalability.Through many tests and field applications,this paper concludes that the performance and stability of this module is excellent,and it meets the strict requirement of HVDC applications.
