Design Of Underwater Acoustic Communication Software Architecture Based On Multi Core DSP And Implementation Of NATO Based Underwater Acoustic Telephone

At present,the integration of integrated sonar system is an important section being researched in the field of sonar system.With the continuous optimization and resource sharing of sonar system,the softwarization of sonar function has become an inevitable trend.Given the demand for processing metadata and exchanging complex information,higher requirements for the processing capability of digital signal processing platform have been requested.In order to adapt to the development of the sonar system,promote the expansion of national defense technology industry,this essay aims to,combined with related tasks outlined for our military merchandises,develop the architectural design of submarine acoustic communication software based on TMS320C6678 multi core DSP.Firstly,this essays outlines the development of the architectural design of underwater acoustic communication software based on TMS320C6678 multi core DSP,which includes,the optimized allocation for the hardware resource,the design of the application method of the internal and the external connection port of the submarine acoustic communication software;the task designation of the submarine acoustic communication software based on embedded operating system EneaOSEck,and the allocation for the hardware resource of TMS320C6678 multi core DSP.Then,this essay discusses the realization of the underwater acoustic phone function under the NATO system based on the architecture of the acoustic communication software.Namely,outlining the process of the TMS320C6678 multi core DSP submarine phone,on the basis of the simulation of the submarine phone under the NATO system.Meanwhile,an engineering realization of the TMS320C6678 multi core DSP is also introduced,including user's engineering configuration file,application space allocation file,enabling connection port and application optimization.In addition,a simulator for signal optimization under laboratory environment is designed.In the phase of laboratory testing,array data and system display console data are collected for submarine acoustic communication software.Finally,analytical experiments of the NATO system submarine phone under laboratory and marine environment are carried out.The result of laboratory and marine experiment shows that the performance of the TMS320C6678 multi core DSP underwater acoustic phone is favorable,which verifies the rationale and possibility for the architecture of the submarineacoustic communication software,underlying a reliable basis for future researches on the integration of sonar system.
