This is a 3U OpenVPX Ruggedized, Extended Temperature (DTSL15) Controller Board, with Intel(R) Xeon(R) D processor and Linux OS, offering high-performance, flexibility, and robust signal processing and communication protocols. The board supports large-scale multicore computation and multiple I/O interfaces for a variety of applications. It provides high-end, resilient signal processing capabilities, such as FPGA-based signal processing and higher order interpolation filters for audio, video, avionics, and radar signal processing. Additionally, the board includes a pair Intel® Xeon® D processors, DDR4 memory, bus switches, and an XMC expansion slot to accommodate user-specified VPX modules such as FPGA boards, GbE ports, and H.264/MPEG2/JPEG processors. The board also features an extended temperature range from -40°C to +85°C, allowing extended operation in cold temperatures to meet harsh environmental requirements.
