基于FPGA的高速连续数据采集系统的设计

The Design of a FPGA-based High-speed Continuous Data Acquisition System

本文提出了一种用于雷达回波信号采集的高速数据采集系统。该系统实现了对数十兆赫的回波信号进行连续的采样和存储。系统通过FPGA控制数据连续采集、缓冲,通过PCI9056将缓冲区数据转移到硬盘管理卡,由硬盘管理卡将数据存入海量硬盘阵列。

This paper describes a FPGA-based high-speed data acquisition system, which can support radar echo signal acquisition application. This system can acquire high-speed echo single with frequency up to several hundred thousands Hz and store these data continuously. We use FPGA to control data acquiring and data buffering, and transfer those buffered data to the Hard Disk master card. Through the Hard Disk master card, we store the data to the Hard Disk array.
