Acromag’s (Wixom, MI) new VPX-VLX series of 3U VPX FPGA boards feature a configurable Xilinx® Virtex®-5 FPGA enhanced with multiple high-speed memory buffers and a high-throughput PCIe interface. Field I/O interfaces to the FPGA via the rear P2 connector and/or with optional front mezzanine plug-in I/O modules. Typical uses include signal intelligence, image processing, hardware simulation, and communications.

VPX-VLX series of 3U VPX FPGA boards feature a configurable Xilinx® Virtex®-5 FPGA enhanced with multiple high-speed memory buffers and a high-throughput PCIe interface.
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.

Large, high-speed memory banks provide efficient data handling. Dual-ported 1M x 64-bit SRAM enables highspeed DMA transfers to/from the CPU while simultaneously writing data to memory. Generous 32M × 32-bit DDR2 SDRAM buffers give the FPGA fast access to I/O port data. FPGA code loads from the PCIe bus or from on-board flash memory. A double fat pipe 4-lane PCIe interface ensures very fast data throughput. 64 I/O lines are accessible through the rear (P2) connector. A series of AXM extension modules is 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.
