FPGA在高频成像声纳中的应用

Application of FPGA In the High Frequency Imaging Sonar

FPGA(现场可编程门阵列)是由掩膜可编程门阵列和PLD(可编程逻辑器件)演变而来的,FPGA既有掩膜可编程门阵列的高逻辑密度和通用性,又有PLD的可编程特性。FPGA技术的发展使得单个芯片上集成的逻辑门数越来越多,能实现的功能越来越复杂。它具有抗干扰能力强、处理速度快、编程速度快、编程方便等特点。本文将其应用于高频成像声纳设计中,完成数据采集与光纤传输的任务。

FPGA(Field Programmable Gate Array)generates from masked progr am mable gate array and PLD (Programmable Logical Device).It has not only the h igh logical intensity and generalization of masked programmable logical array b ut also the characteristics of PLD.With the development of FPGA technique, more and more logical gates are integrated in one single chip and complex tasks can be achieved.FPGA has the advantages of high resistant distur-bance,high processing speed,easy to program and so on.It has been used in the design of high frequency imaging sonar to complete the task of data sampling and fiber tr ansmission.
