摘要
针对一套用于AUV(autonomous underwater vehicle)自救系统的水声应答器,提出了基于大规模逻辑器件FPGA(field-programmable gate array)的软件化分频及编码。在QuartusⅡ开发环境下,采用Verilog HDL(hardware—description—language)语言及参数化的程序设计方法,在FPGA上实现了这种软件式的分频和频率编码,与原本数字电路的实现方式比较,提高了该水声应答器系统的可靠性和集成度,降低了功耗,同时使系统的可扩展性等到了增强。
Based on a set of acoustic response using to the AUV（autonomous underwater vehicle） self-help system,this thesis proposes the software frequency coding,which is based on a large scale of logic devices FGPA（field-programmable gate array）.under the circumstances of QuartusⅡ,by comparing with the original digital circuits realization,using the verilog language HDL（hardware—description—language）and the parametric Programming method which realizes the software frequency coding in FPGA improves the reliability and integration of the acoustic response system,reduces power,and strengthen the scalability of the system.
