Overview
National Instruments reconfigurable I/O (RIO) technology gives you the ability to define your own custom measurement hardware circuitry using reconfigurable field-programmable
gate array (FPGA) chips and NI LabVIEW graphical development tools. NI R Series multifunction RIO devices offer the best combination of value and performance by integrating
this FPGA technology with eight analog inputs, eight analog outputs, and 96 digital I/O lines, all into a single device that is offered on standard PC form factors such as PCI, PCI
Express, and PXI/CompactPCI. Using the LabVIEW FPGA Module, you can create your own hardware personalities for custom data acquisition, high-speed control, digital
communications protocols, sensor simulation, hardware-in-the-loop test, and onboard signal processing without in-depth knowledge of hardware description languages.

Application and Technology
Graphical Programming with LabVIEW FPGA
The LabVIEW FPGA Module uses LabVIEW embedded technology to extend LabVIEW graphical development and target FPGAs on NI RIO hardware. LabVIEW is distinctly
suited for FPGA programming because it clearly represents parallelism and data flow. With LabVIEW FPGA, you can create custom measurement and control hardware without
low-level hardware description languages or board-level design. You can use this custom hardware for unique timing and triggering routines, ultrahigh-speed control, interfacing to
digital protocols, digital signal processing (DSP), and many other applications requiring high-speed hardware reliability and tight determinism.
Low-Cost Signal Conditioning and Channel Expansion
The NI 9151 R Series expansion chassis connects directly to any digital connector on R Series devices and houses up to four C Series I/O modules for industrial signal
conditioning, I/O channel expansion, and direct sensor connectivity.
New Virtex-5 FPGAs
The new NI 784xR and NI 785xR devices use new Virtex-5 FPGAs with improved optimization capabilities that provide faster code execution and increased code capacity. These
Virtex-5 FPGAs feature a new six-input lookup table (LUT) architecture for substantially improved resource utilization as well as DSP48 slices that make it possible for you to
implement more complex digital signal processing at faster rates. Previous-generation Virtex-II FPGAs use four-input LUTs for up to 16 combinations of digital logic values. The
new Virtex-5 FPGAs use six-input LUTs for up to 64 combinations, increasing the amount of logic that you can implement per slice. In addition, the slices themselves are placed in
closer proximity to each other to reduce the propagation delay of electrons and increase overall execution rates. The single-cycle timed loop structure in LabVIEW FPGA takes full
advantage of six-input LUTs for substantially improved resource utilization. This means you can optimize more LabVIEW FPGA code to fit within Virtex-5 FPGAs and perform
more operations per clock cycle.
Figure 1. General logic benchmarks show that Virtex-5 FPGAs offer larger sizes when compared to Virtex-II FPGAs.
