VPX 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, VPX systems can run the identical application software, drivers and operating-systems as desktop or industrial PCs. However, VPX chassis support concurrent use of four plug-in cards (depending on need), so it's feasible to configure sophisticated systems with myriad I/O connections.

Innovative's VPX 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 VPX host CPU. Each of the XMC modules hyperlinked on Illustration 3 may be mated with Innovative's 80260 VPX-XMC adapter to create an VPX I/O card with an Xilinx FPGA whose functionality can be customized to meet application-specific real-time signal processing requirements. Additionally, Innovative's VPX cards support direct inter-board communication via dedicated backplane 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.
