Implementation of Acoustic Array Signal Parallel Processing Based on IP Interconnect and DSP

Parallel processing system of scalable acoustic array signal had been designed based on IP interconnect.The system adopted two pieces TMS320DM642 of TI company as a Processing node,and implement board interconnect processing in parallel through IP network.The system can increase or reduce number of processing node according to Transducer array element and requirements of processing speed.Each processing node of sonar system connected with data acquisition conversion unit by TCP/IP network,and improved data processing ability by increasing processing nodes.
