PXI Express is an ideal platform for complex RADAR/LIDAR, wireless communications, or automated test systems. Each chassis combines an multi-core Intel CPU running Windows/Linux with a backplane providing four or eight-lane high-bandwidth PCI Express connections to each payload slot, capable of sustained 3400-7000 MB/s data flow. Consequently, PXIe systems can run the identical application software, drivers and operating-systems as desktop or industrial PCs. However, PXIe chassis support concurrent use of six, nine or eighteen plug-in cards (depending on need), so it's feasible to configure sophisticated systems with myriad I/O connections.
Moreover, reference clock and trigger signals are also available on the PXIe backplane, simplifying the creation of synchronous-sample systems such as phased array or beam-steering systems, software defined radios and surveillance/ communications systems which typically require wide channel counts and high inter-module bandwidth.
Illustration 4: Hyperlinked list of PXIe I/O cards with user-programmable Xilinx FPGAs for real-time digital signal processingInnovative's PXIe cards differ from conventional I/O cards from other vendors since each provides a user-programmable FPGA capable of off-loading computationally-intensive signal processing tasks from the PXIe host CPU. Each of the XMC modules hyperlinked on Illustration 4 may be mated with Innovative's 80341 PXIe-XMC adapter to create an 8HP PXIe I/O card with an Xilinx FPGA whose functionality can be customized to meet application-specific real-time signal processing requirements. Additionally, Innovative's PXIe cards support direct inter-board communication via dedicated, front-panel QSFP connections. This provides low-latency side-band communications directly between modules, independent of the backplane's PCIe communications channel. This is an essential capability for beam steering and coprocessing applications unique to Innovative products.
Illustration 5: Hyperlinked list of PXIe I/O card with Zynq system-on-chip for real-time control/analysisInnovative's COPious-PXIe I/O cards employ a Zynq system-on-chip (SoC) instead of an FPGA. These SoC devices combine dual ARM CPU cores with Kintex 7 FPGA fabric - a key differentiator. This is an ideal architecture for latency-critical applications such as servo control, range finding (RADAR/LIDAR), etc. Each of the FMC I/O cards hyperlinked on Illustration 5 may be mated to the COPious-PXIe SoC -equipped carrier card whose logic fabric may be user-customized to meet application-specific real-time signal processing requirements.
