Design and Research of TigerSHARC Sonar Signal Processing System

Yingmin Wang

Abstract

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-TS101 chip Link port extensions is used,the real-time functions of each module and the system scalability are well realized,and experimental analysis shows the superiority of this sonar signal processing system based on the TigerSHARC.
