基于SOPC的高速数据采集系统

The high speed data acquisition system based on SOPC

本文研究并实现了基于SOPC的高速数据采集系统,前端利用高速A/D将模拟信号转换成两路的数字信号交叉输出,应用乒乓操作的方式分别将每一路数字信号再交叉写入两路并行FIFO缓冲器,缓冲器中的数据经过重组后存储到RAM中,由NIOSII软核处理器对数据进行处理和显示。

This paper introduces a high speed data acquisition system based on SOPC. It uses a high-speed A/D converts the analog signal to two channels interleaved digital data output, with the ping-pong operation each channel is interleaved delivered to two parallel FIFO buffers, then the data in these buffers are recombined and stored in the RAM, in the end the NIOS II core computes these data.
