介绍一种基于嵌入式Linux的远程多通道数据采集卡。采用协处理FPGA芯片SPARTAN3 XC3S400实现多通道数据采集,CY7C028高速双口RAM用来缓存采集的数据,最后通过核心处理器S3C2410A来完成多通道参数设定、采样数据读取以及控制网络传输芯片8900CSA实现数据远程传输功能。
This paper introduces a remote multi-channel data acquisition card based on embedded Linux. Using coprocessor FPGA chip SPARTAN3 XC3S400 to achieve multi-channel data acquisition, CY7C028 high-speed dual-port RAM used to cache the collected data, and finally through the core processor S3C2410A to complete the multi-channel parameter setting, sampling data read and control network transmission chip 8900CSA Data remote transmission function.
