摘　　要：为满足宽带雷达信号处理对处理速度和实时性的要求,提出一种基于4片ADSP-TS201S的DSP并行系统设计。通过分析比较3种ADSP-TS201S的并行处理结构,结合实际需求,采用外部总线共享与链路口混合耦合的多DSP并行处理系统方案。在设计中,利用FPGA实现数据传输和CPCI接口的逻辑控制。经验证,该系统具有运算能力强、片间通信灵活、并行处理效率高等优点。In order to satisfy the request for dealing with the wide band radar signal which needs fast and real-time processing, the design of multi-DSP parallel system based on four ADSP-TS201Ss is proposed. Proceeding from practical requests, a scheme of the multi-DSP parallel processing system which couples the external BUS sharing and the link ports is adopted by analyzing and comparing with parallel processing structures of three kinds of ADSP-TS201Ss. The data transmission and CPCI interface logic control are realized by FPGA. The demonstration shows that this system has several advantages such as strong calculation ability, flexible communication within different DSPs and high parallel processing efficiency, etc.
