基于S3C2440和AD9248的高速采集系统的设计

摘要

A high speed data acquisition system is designed based on a high-speed A/D, FIFO and the ARM9. ARM9 is used to control A/D's conversion and FIFO's read and write, and large-capacity onboard data storage, as well as to achieve longer continuous acquisition. At the same time the design of network interface and USB interface to the preservation and transmission of data, GPS timing module interface to achieve data acquirement multiple sites at the same time.%设计了一个利用高速A/D、FIFO以及ARM9实现的高速数据采集系统.通过ARM9控制高速A/D转换和FIFO的读写,并采用大容量的板载数据存储器,可以实现较长时间的连续采集.设计了网络接口和USB接口实现数据的保存和传输,并设计了GPS授时模块接口以实现多个站点的同时数据采集.
