摘　　要：提出了一种由6片ADSP-21161构成的多DSP并行处理结构的高速数据采集系统的设计方案,对其中高速A/D、高速缓存、多DSP并行处理方式等内容进行了讨论,提出了更为有效的同步控制方式。该设计方案电路简单,具有运算能力强、I/O带宽宽、通信手段多样、能灵活地改变拓扑结构、可扩展性和通用性强等特点,并且以此并行计算结构为核心设计实现了通用高速实时雷达信号处理系统。This paper proposed a kind of multi-DSP parallel processing structure high speed data gathering system which constitutes by 6 piece of ADSP - 21161, and discuss high speed A/D, high speed buffer, and multi-DSP parallel processing way, proposed the more effective synchronized control mode. This design which have the characteristic as simple electric circuit, strong operational capability, I/ O band width wider, communication means diverse, topology can change, strong extendibility and versatility, and based on this parallel computation structure as the core design realized general high speed real-rime radar signal processing system.
