摘要
文中主要介绍针对不同采样频率的多路数据的采集与存储方法。重点阐述了基于A3P125型FPGA的多路数据采集与存储测试系统的编帧、方案设计、硬件电路及软件电路设计方法,并且介绍了对于该系统的一种软件自测方法。实验测试结果表明:该设计系统能很好地完成多路的采集,其采集精度1%,采样路数可以根据需要进行扩展。
A multi-channel data processing and storage system with different sampling frequency was presented.The system was designed based on an A3P125 type FPGA.The edit frame mode,the project frame,and the hardware and software circuit design method were expatiated in detail.In order to measure the multi-channel data processing and storage system,a software measure way was introduced.The experiment results show that the measure system can carry out to multi-channel data processing.The system can reach the precision of 1%,and its sampling signal routes can be expanded in the light of the user＇s need.
