| 摘 要： | 本文利用高速A/D器件、FPGA和USB控制器设计了一个高速数据采集卡。系统利用高速AD器件和FPGA来完成前端的数据转换和存储。数据先被存储在外部FIFO中,之后由USB控制器将缓存中的数据通过GPIF方式快速读入并通过USB接口传递给上位机,最后由上位机完成后端的相关处理。

| Abstract: | This paper presents a data acquisition card composed of a high speed A/D convertor, FPGA and an USB controller.The high speed A/D convertor and FPGA is used to convert and store data from the external FIFO. Then the USB controller reads the stored data by GPIF method and transfers them to PC with USB interface. Finally the PC finishes the back-end data processing. |
