Curtiss-Wright Controls Embedded Computing has announced its first 3U OpenVPX general purpose graphics processing unit (GPGPU)- multi-core engine, the VPX3-491 GPU Application Accelerator. The small form factor VPX3-491 features an NVIDIA GPU based on the NVIDIA Fermi architecture with 240 CUDA cores. Integrated into subsystem, the VPX3-491 functions as a co-processor attached to a host Intel-processor board and takes advantage of the new PCIe Expansion Plane definitions in the VITA 65 OpenVPX standard to provide off the shelf backplane support for high-speed interconnection between pairs of SBC/GPU. The combination of 2nd Generation Intel processors, gen2 PCI Express interconnect and 240 NVIDIA CUDA cores raises the performance bar for compact systems for demanding military DSP applications such as C4ISR, EO/IR, and SatCom.
The VPX3-491 supports its high performance GPU processor with a 2 Gbyte, 256-bit wide, 80 Gbyte/s GDDR5 memory subsystem designed to eliminate data bottlenecks and support large signal processing datasets into the onboard memory. The VPX3-491 supports a full 16-lane Gen2 PCIe interface to the backplane, supporting the maximum possible bandwidth between host and GPU. The VPX3-491also supports 8-lane and 4-lane PCIe interfaces. The VPX3-491 is designed to work with Intel processor- based SBCs, such as the Curtiss-Wright VPX3-1256 2nd Generation Intel Core single board computer.
The VPX3-491 adds a new high-end floating point computing capability to Curtiss Wrights large portfolio of 3U processing solutions. Customers can construct systems with performance that until recently was the domain of much larger 6U implementations, but with the SwaP characteristics needed for weight-constrained air-borne and space-constrained ground vehicle applications. Curtiss Wright 3U products offer technologies that include 2nd Generation Core i7 processing, Freescale processors with Altivec, Xilinx Virtex 6 FPGAs, High-speed A/D and D/A FMCs, GPGPUs and Ethernet Switching.
