The DuraCOR 312 is an ultra-small form factor (USFF) modular mission computer designed for rugged environments. It is built around the high-performance, yet power-efficient NVIDIA® Jetson™ industrial TX2i "supercomputer-on-a-module." This system is integrated into a miniature rugged chassis with MIL-grade high-density connectors, making it suitable for mobile, airborne, ground, manned, and unmanned vehicle and sensor platforms where size, weight, power, and cost (SWaP-C) are critical.
Function Description:
The DuraCOR 312 combines powerful NVIDIA Pascal™/CUDA-core GPU signal processing with a 64-bit hex-core ARMv8 heterogeneous multi-processing (HMP) architecture. This architecture boasts one of the highest computing FLOPS-per-watt ratios on the market. It supports Max-Q and Max-P dynamic energy profiles, offers larger memory bandwidth, and includes CANbus support, delivering up to twice the performance or power efficiency of TX1-based systems with native vehicle bus interfaces.
The unit features a modular system design with multiple Mini-PCIe I/O card slots, high-speed M.2 internal storage, and removable SATA Flash SSD capabilities. An aerospace-grade power supply supports 50ms power hold-up, and the fan-less IP67-rated mechanical package is designed for wide temperatures and harsh shock and vibration.
