基于FPGA的高速实时数据采集存储系统设计

摘要

介绍一种基于FPGA的数据采集存储器的设计,以sparten2系列的XC2S200芯片为主控单元,结合相关外围电路和FLASH存储器K9F2G08UOM共同组成存储系统.采用双存储设计,增强了系统可靠性,实现对一路高速10MbpsPCM数据码流和一路3.75M异步串行图像数据的采集和存储.同时与测试台和计算机配合完成对采集数据的实时监测.%This paper introduced the data acquisition and storage system design based on FPGA. It took the chip XC2S200 as the main control unit that come from sparten2 series. The storage system was composed of the associated peripheral circuits and the FLASH memory K9F2G08UOM together. The design adopted double storages,it achieved the acquisition and the storage of one 10 Mbps PCM streams data and one 3. 75 M asynchronous serial image data. At the same time, the storage system cooperate with the computer and the ground test station completed mohitoring the real-time collection data.
