摘要
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。
Based on embedded Linux, a kind of long-distance and multi-channels Data Acquisition card is introduced. The FPGA coprocessor SPARTAN3 XC3S400 is used to accomplish multi -channels data acquisitions, dual port RAM CY7C028 is used as a data buffer, and finally core processor S3C2410A is used to set the parameters and read the data of the channels, and control the Ethemet Controller CS8900A to implement long-distance data transmission function.
