3U OpenVPX graphics processor for military imaging and DSP applications introduced by Curtiss-Wright

ASHBURN, Va., 9 Dec. 2011. Curtiss-Wright Controls Embedded Computing in Ashburn, Va., is introducing the VPX3-491 GPU Application Accelerator 3U OpenVPX general-purpose graphics processing unit (GPGPU) multi-core engine for demanding military digital signal processing (DSP) in command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR), electro-optical and infrared processing, and satellite communications. The VPX3-491 has an NVIDIA graphics processing unit (GPU) based on the NVIDIA Fermi architecture with 240 CUDA cores.

The embedded image-processing board functions as a co-processor attached to a host Intel-processor board and takes advantage of the PCI Express Expansion Plane definitions in the VITA 65 OpenVPX standard. The board has been selected for a demanding military image processing program, Curtiss-Wright officials say.

The newest generation of NVIDIA processors have larger internal shared memories, a L2 cache, and unified memory addressing to improve performance. The VPX3-491 has a 2 gigabyte, 256-bit wide, 80-gigabyte-per-second GDDR5 memory subsystem, as well as a 16-lane Gen2 PCI Express interface to the backplane. The VPX3-491 also supports 8-lane and 4-lane PCI Express interfaces.

The VPX3-491 is designed to work with Intel processor- based single-board computers. For more information contact Curtiss-Wright online at
