摘　　要：设计一个基于FPGA和USB 2.0接口控制芯片的高速线阵CCD声光信号采集系统。FPGA是硬件电路系统的核心,主要完成线阵CCD时序脉冲的产生,专用A/D芯片的采样控制以及FIFO缓存数据的片内配置,并通过USB 2.0接口与上位机实现通信。讨论并开发了USB 2.0接口控制芯片的固件程序、USB驱动程序及上位机应用程序。实验结果表明,系统达到了设计要求,可广泛应用于相关领域的信号检测。The high speed linear array CCD acoustic- optical signal acquisition system based on FPGA and USB 2.0 interface control chip is designed in this paper. FPGA is the core of the hardware circuitry. The generation of sequence pulse of linear array CCD and the sampling control of special A / D chip are completed by FPGA. The FIFO cache data is configured in FPGA chip. The PC communication is achieved through the USB 2.0 interface. The firmware of USB 2.0 interface control chip, USB drivers and PC application are discussed. The experimental results show that the system design meet design requirements and the system can be used in the detection of acoustic- optical signal widely.
