Toni_McConnel-November 04, 2012

The VPX3-453 FPGA module from Curtiss-Wright Controls Defense Solutions is the company's second Xilinx Virtex-6 FPGA-based VPX digital signal processing (DSP) engine, in a compact 3U VPX form-factor. The VPX3-453 is a high performance DSP engine that combines a Xilinx Virtex-6 FPGA and a Freescale Power Architecture MPC8640D processor.

This small form-factor 3U VPX (VITA 46/48) card is targeted for SWaP-constrained environments and is designed to support the full -40 + 85 deg C rugged operating temperature range. The VPX3-453 speeds and simplifies the integration of advanced DSP and image processing into embedded systems designed for demanding Radar Processing, Signal Intelligence (SIGINT), ISR, Image Processing, and Electronic Warfare applications.


The VPX3-453 features Gen 2 PCIe with Non-Transparent Bridge support for better handling of large 3U systems, as well as additional I/O flexibility to the backplane from either the XMC or FPGA. To better support its on-board Virtex-6 FPGA, the board features extensive FPGA memory bandwidth, including 2.4 GB/s SDRAM and 4.8 GB/s SRAM performance. FPGA memory support includes one (1) bank of DDR2 SDRAM and two (2) banks of QDR-II+ SRAM. Two (2) 4-lane high-speed serial ports to the backplane and an additional port to the XMC site provide a total of 7.5GB/s bandwidth into and out of the FPGA in addition to the primary 4-lane PCI Express (PCIe) link to the on-board fabric.
