NI FlexRIO hardware provides flexible, customizable I/O for NI LabVIEW FPGA. It features two parts: NI FlexRIO field-programmable gate array (FPGA) modules for PXI and NI FlexRIO adapter modules. Together, they form a high-performance, reconfigurable instrument programmable with LabVIEW FPGA software.
The PXI-7954R NI FlexRIO FPGA module features a Virtex-5 LX110 FPGA and 128 MB of onboard DDR2 DRAM. The new Virtex-5 FPGA architecture is optimized to execute faster and more efficiently using single-cycle timed loops in LabVIEW FPGA. This means you can optimize more LabVIEW FPGA code to fit within Virtex-5 FPGAs and can execute more operations per clock cycle.
Build Your Own I/O for LabVIEW FPGA
Use the NI FlexRIO Adapter Module Development Kit (MDK) to build custom I/O to meet your exact application needs. The NI FlexRIO card edge connector offers direct access to the raw digital I/O pins of the FPGA. Each pin is capable of low-voltage differential signaling (LVDS) rates up to 1 Gb/s and single-ended rates up to 400 Mb/s.
100 MHz Digital I/O Adapter Module
All NI FlexRIO FPGA modules are compatible with the NI 6581 high-speed digital adapter module. This adapter module offers 54 single-ended digital I/O lines with selectable voltage levels of 1.8, 2.5, and 3.3 V (5 V TTL-compatible) and the option to provide any external voltage reference from 1.8 to 5.5 V.
