摘　　要：提出针对光谱仪器的CCD数据采集SoPC系统,采用并行A/D及异步FIFO转换和缓冲数据。利用Verilog HDL硬件描述语言编写驱动模块,把CCD、A/D和FIFO输入的驱动控制集成与一体,得到严格的时序保证;建立Avalon StreamingSource接口部件,为FIFO输入提供流数据;调用SLS USB20HR软核实现USB2.0接口;实现NIOSⅡ数据采集软件设计、编译和调试。A SoPC （System On a Programmable Chip ）system was designed for the CCD data acquisition in spectrometer. By using parallel A/D and asynchronous FIFO converting and buffering data. Verilog HDL hardware description language is used to realize the driver module. The drive mode integrates the CCD, A/D and the FIFO controller and driver, so that it guarantees strict synchronous timing, creates Avalon Streaming Source Interface component,provides flow data for the FIFO input; calls SLS USB20HR soft IP core realized USB2.0 interface, and achieves NIOS Ⅱ data acquisition software design, comply and debug.
