NI FPGA cRIO实时控制器[0]

Posted on 2023年11月14日 by

NI cRIO-9066+NI9220+NI9265

硬件价格3.5W  labviewer软件费6.5W

国产替代是芒果树,其典型的硬件价格在1.3w左右。

常用的型号P812,S813

P812是不带外壳的

S813

系统的大概原理:

x86负责启动到linux RT系统下,估计有专门的linux下的实时守护程序用于将编译的FPGA程序下发到xilinx芯片中,同时将FPGA数据通过PCI总线通过DMA的方式转移到x86内存中,再由x86将其通过网口传输到上位机。

目前还不清楚FPGA在这块电路上的具体作用。

欢迎回来
