National Instruments has introduced four new adapter modules for its FlexRIO product family, which provides FPGA-based reconfigurable I/O (RIO) for PXI systems, using the LabVIEW FPGA Module software.
The user-configurable FlexRIO product family takes advantage of industry-leading PXI hardware and software integration to give engineers a commercial off-the-shelf (COTS) solution that is specifically designed to more easily implement field-programmable gate array (FPGA) technology for advanced automated test and measurement systems. FlexRIO solutions combine two distinct hardware components, a programmable PXI or PXI Express-based FPGA module and an I/O adapter module. The four new adapter modules are ideal for real-time measurements, non-destructive test (NDT) and ultrasound applications, communications systems and scientific research.
The NI 5761 is a four-channel, 14-bit, 250 MSps digitiser adapter module designed to meet a wide range of signal processing application needs including communications system design, intermediate frequency (IF) acquisition, multiple input, multiple output (MIMO), radar and scientific research. The NI 5751 is a 16-channel, 50 MSps, 14-bit digitiser adapter module for test and measurement in areas such as experimental physics, NDT and medical imaging. The NI 5752 is a 32-channel, 50 MSps, 12-bit digitiser adapter module optimised for NDT and ultrasound applications. It includes AC-coupled differential inputs with integrated VGAs and time-varying gain curves, as well as 16 digital outputs for pulser stimulus. Finally, the NI 6583 digital adapter module has 32 single-ended and 16 LVDS/mLVDS channels, with data rates up to 300 Mbps for test and communication requiring mixed digital logic.
Engineers can control and reconfigure the FPGA on the FlexRIO host module using the LabVIEW FPGA software. LabVIEW FPGA is distinctly suited for user-configurable FPGA programming because it clearly represents parallelism and dataflow programming, making it easier for engineers to target FPGAs without VHDL or Verilog knowledge.
The latest version of LabVIEW FPGA incorporates enhancements that specifically address the increasing demands of advanced test systems. It includes improved integration with existing and off-the-shelf IP including direct compatibility with Xilinx IP blocks such as filters, fast Fourier transforms (FFTs), memories and first-in-first-out memory buffers (FIFOs). Better simulation capabilities make LabVIEW FPGA debugging and verification faster and more accurate with an IP behavioural simulation engine and tool integration with Mentor Graphics ModelSim. LabVIEW FPGA also draws on the support of LabVIEW FPGA IPNet, an online resource that helps engineers browse, download and share the latest IP for FPGA designs.
