3U VPX Graphics Board Features NVIDIA Kepler Architecture

GE-AThe GRA112 3U VPX graphics board has been designed by GE for demanding graphical applications, as well as GPGPU applications such as intelligence, surveillance, reconnaissance, radar and sonar. The board features a 384-core NVIDIA Kepler architecture-based EXK107 GPU and 2 GB of GDDR5 memory, which together, make the GRA112 more powerful than its predecessor, the GRA111, for which it provides a pin-compatible technology insertion upgrade. Dual, independent channels mean that it is capable of driving RGB analog component video, digital DVI 1.0, and HDMI standards. The NVIDIA GPU is capable of 622 GFLOPS, 64 GBytes/second internal memory bandwidth, and 16 GBytes/second external PCI Express bandwidth. For radar processing, double-precision floating point hardware will minimize the impact of artifacts introduced by single-precision processing. The GRA112’s video input capability allows integration of sensor data using RS170, NTSC or PAL video formats, and its development environment includes support for OpenCL, OpenGL, NVIDIA PureVideo Technology, NVIDIA PhysX and Microsoft DirectX.
