A new series of 3U VPX FPGA boards features a configurable Xilinx Virtex-5 FPGA enhanced with multiple high-speed memory buffers and a high-throughput PCIe interface. Field I/O signals interface to the FPGA via the rear P2 connector and/or with optional front mezzanine plug-in I/O modules result in a powerful and flexible signal processor card. 

Three models provide a choice of logic-optimized FPGAs to match the performance requirements. Cards can be ordered with a Xilinx VLX85T, VLX110T, or VLX155T FPGA featuring up to 155,000 logic cells and 128 DSP48E slices. Each model is available in a format designed for use in air-cooled or conduction-cooled systems suitable for -40° to 85°C operation. 64 I/O lines are accessible through the rear (P2) connector. A series of AXM extension modules are available to provide additional front-end A/D, RS-485, CMOS, or LVDS I/O channels through a mezzanine connector on the front of the board.

Acromag’s Engineering Design Kit provides utilities to help users develop custom programs, load VHDL into the FPGA and to establish DMA transfers between the FPGA and the CPU. The kit includes a compiled FPGA file and example VHDL code provided as selectable blocks with examples for the local bus interface, read/writes and change-of-state interrupts to the PCI bus. A JTAG interface allows users to perform onboard VHDL simulation. Further analysis is supported with a ChipScope Pro interface. For real-time and open source applications, Acromag offers C libraries for VxWorks, Linux and other operating systems. The boards start at $7,100 with several options for FPGA logic capacity and conduction-cooled extended temperature operation.
