摘　　要：采用大规模的TigerSHARC DSP高速并行信号处理板对吊放声呐信号处理系统进行设计与研究。该处理板共有8片ADSP-TS101芯片,整板采用共享外部总线和分布式并行处理相结合的网络互联结构,大大增强了DSP芯片之间的I/O吞吐量和处理速度,在设计中充分利用了ADSP-TS101芯片强大的Link口扩展功能,使各模块功能的实时性及系统的可扩展性得到很好的实现,并通过实验分析证明了基于TigerSHARC的声呐信号处理系统的优越性。Large-scale TigerSHARC DSP high-speed parallel signal processing board is used to design and research the dipping sonar signal processing system, The processing board is a total of eight ADSP-TS101 chips, shared external bus and distributed parallel processing network interconnection structure are adopted and greatly increase the I/O throughput capacity and processing speed between the DSP chips. In the design, ADSP-TSIOI chip Link port extensions is used, the real-time functions of each module and the system scalability axe well realized, and experimental analysis shows the superiority of this sonar signal processing system based on the TigerSHARC.
