Abstract: A FPGA-based intelligent storage control system is provided that includes a FLASH main controller; a FLASH command former and an address generator with a memory function, for generating level signal of cross clock domain and automatically avoiding out-of-bounds writing. A configuration data former provides for driving and controlling a configuration writing in function by a writing configuration drive signal. An automatic reading configurator provides automatic configuration reading by internal drive signal to drive. A main data and auxiliary data former provides continuous storage of main data according to ping-pong operation for unequal width RAM operation. A FLASH data reading buffer and a multi-interface external drive module are also present. The system is applicable to an unmanned underwater vehicle and underwater acoustic equipment.

Abstract: A field-programmable gate array (FPGA)-based real-time processing system applied to underwater acoustic positioning and realizing reconfigurability and multiple output is provided. The system includes a multi-interface control and command parsing module for automatically completing sample information transmission and command parsing; a finite-state machine (FSM) of sample management 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. A FPGA-based real-time processing control method is also provided that is applied to underwater acoustic positioning and realizing reconfigurability and multiple output.
