Design of a Multi-Channel Parallel Data Acquisition System Based on FPGA

To meet the high-synchronization requirements of multi-channel data acquisition in shallow-water imaging sonar systems, this study designs a 128-channel parallel acquisition system based on an FPGA. The system integrates a Xilinx Zynq-7000 FPGA and 64 LTC1407A-1 dual-channel 14-bit ADCs, achieving precise synchronization through Verilog programming. A three-level buffering structure ensures data reliability and real-time performance. Experimental results confirm the system’s ability to efficiently acquire synchronized data from 128 channels, providing a reliable solution for sonar applications.
