FPGA-BASED REAL-TIME PROCESSING SYSTEM AND METHOD APPLIED TO HYDROACOUSTIC POSITIONING AND REALIZING RECONFIGURABILITY AND MULTIPLE OUTPUT

摘要

An FPGA-based real-time processing system applied to hydroacoustic positioning and realizing reconfigurability and multiple output. The system comprises a multi-interface control and command parsing module for automatically completing sample information transmission and command parsing; a sample management finite-state machine for calculating related data and completing splitting, flipping and writing of a sample; a parallel correlation processor group for completing, in parallel, high-performance processing operations regarding a plurality of targets; and a multiple output data former for simultaneously realizing data formation of a multiple output result and outputting a flag bit signal to the outside. The present invention further relates to an FPGA-based real-time processing control method applied to hydroacoustic positioning and realizing reconfigurability and multiple output. The system and the method are used, such that during a whole realization process, under a plurality of array elements and a plurality of targets, high-speed parallel correlation processing is realized, thereby solving problems in terms of real-time performance, universality and anti-noise performance, and effectively realizing high-performance correlation.
