Ni launched four new R-Series i/o modules for PXI platform
in May 2008, National Instruments Co., Ltd. (Ni) launched four new R-Series i/o modules for PXI platform. These modules are equipped with high-performance Xilinx Virtex-5 field programmable gate array (FPGA) chips. Ni pxi-7841r, pxi-7842r, pxi-7851r recent and pxi-7852r modules have 8 analog inputs, 8 analog outputs and 96 digital i/o channels, and the rate of analog input is more than 3.5 times faster than that of previous versions of R series devices. These new modules provide engineers and scientists with immediately available hardware; Not only that, these hardware can also be programmed graphically through NI LabVIEW FPGA Software, and customized functions can be carried out on the board to meet the applications that need special timing and trigger conditions, such as data analysis and deterministic i/o control
"the unparalleled flexibility of FPGA technology makes it the preferred solution for complex embedded system design, high-performance data acquisition and test applications." Dr. James truchard, President, co-founder and CEO of Ni company, said, "with the continuous investment in FPGA technologies such as new R-Series devices and LabVIEW FPGA Software, Ni company is providing a closely integrated platform for test engineers and embedded programmers, so that they can easily give full play to the powerful potential of FPGA technology."
using pxi-7841r and pxi-7842r, engineers and scientists can obtain 16 bit resolution analog input with a sampling rate of up to 200ks/s/ch; With pxi-7851r and pxi-7852r, the sampling rate can reach 750 KS/S/Ch. At the same time, compared with the original R-Series devices, the new R-Series modules are equipped with Virtex-5 LX30 or Virtex-5 LX50 FPGA chips, which can provide improved optimization functions, make code execution faster, and greatly improve the code efficiency of LabVIEW. Virtex-5 series FPGA chips have a 6-input LUT structure, which greatly improves the application of resources. DSP slice on the chip can enable users to complete more complex digital signal processing functions at a faster speed. These new R-Series modules combine high-speed i/o and Virtex-5 FPGA, making them the preferred solution for high-performance processing and control applications in the fields of automation, life sciences, aviation and national defense
"advanced Virtex-5 series FPGAs provide designers of embedded design and test applications with unparalleled computing performance and system integration capabilities." Steve Douglas (vice president and senior product manager of Xilinx company) said, "by integrating FPGA technology into the new R-Series equipment, the n-ring stiffness testing machine has a wide variety of high-performance hardware provided by I company. These hardware can be easily optimized by using L4. The buffer has poor oil return condition and abview graphical programming, so as to shorten the design cycle and the time required to be put into the market."
with PXI instruments, engineers and scientists can choose from more than 1500 instruments (including signal generator, RF, power supply and switch module), and configure the instruments in the software to complete the required functions, so as to self define their applications. The new R series modules further expand this custom function by integrating Virtex-5 FPGAs, which can be programmed using LabVIEW FPGA Software to create user-defined hardware. LabVIEW FPGA Software describes the VHDL code used to configure FPGA through easy-to-use graphical programming, which simplifies the task of customizing hardware. LabVIEW software also provides pre built function blocks and other code optimization techniques to speed up the development of applications. Compared with the traditional customized hardware design method, this graphical system design method, which drives a single car travel boom, that is, the method of tight integration of flexible software and immediately available hardware, can help engineers and scientists design, prototype, test and release customized measurement and embedded design applications at a faster speed and cost-effective cost
