NI FlexRIO设备包括了可采用NI LabVIEW FPGA模块进行编程的现场可编程门阵列（FPGA）模块，以及能提供高性能模拟和数字I/O的适配器模块。

适配器模块是可互换的，并可以在LabVIEW FPGA编程环境下定义可用的I/O。

1. NI FlexRIO FPGA 模块NI FlexRIO FPGA模块的特性包括了采用Xilinx Virtex-5 FPGA的PXI 和 PXI Express装置，板载DRAM，高性能的面向NI应用的集成电路（ASICs），以及为 FPGA提供I/O的NI FlexRIO适配器模块接口。

适配器模块接口包括直接连接到FPGA管脚的132线通用数字I/O，以及定义接口所必需的电源时钟和辅助电路。

您可以将这132线配置为高达400 Mbits/s速率的单端操作和高达1 Gbit/s速率的差分操作， 以及66 Gbits/s (8.

25 GB/s)的最大I/O带宽。

所有线都采用可控阻抗，匹配长度的方式排布，并且差分线对被排布在一起………….

NI FlexRIO 19.0 | 8.5 GbThe National Instruments team is pleased to announce the availability of FlexRIO 19.

0 Drivers which provides support for customers using NI FlexRIO devices.

The latest release include the following new feature, such as support for LabVIEW 2019.

The FlexRIO Driver is an NI instrument driverthat supports FlexRIO devices.

It includes hardware support for FlexRIO devices with integrated I/O, as well as FlexRIO devices with modular I/O, including the PXI FPGA Module for FlexRIO and the various adapter modules for FlexRIO.

For FlexRIO devices with integrated I/O, the FlexRIO Driver also includes an API for streaming as well as support for synchronization with NI-TClk.

The FlexRIO product line was designed for engineers and scientists who need the flexibility of custom hardware without the cost of custom design.

Featuring large, user-programmable FPGAs and high-speed analog, digital, and RF I/O, FlexRIO provides a fully reconfigurable instrument that you can program graphically with LabVIEW or with VHDL/Verilog.

FlexRIO products are available in two architectures.

The first architecture incorporates modular I/O modules that attach to the front of a PXI FPGA Module for FlexRIO and communicate over a parallel digital interface, and the second uses high-speed serial converters and features integrated I/O and Xilinx UltraScale FPGA technology in a single device.

Since 1976, National Instrumentshas equipped engineers and scientists with tools that accelerate productivity, innovation and discovery.

NI’s graphical system design approach to engineering provides an integrated software and hardware platform that speeds the development of any system needing measurement and control.

The company’s long-term vision and focus on improving society through its technology supports the success of its customers, employees, suppliers and shareholders.
