ECO-5931
Effective: 03 Jun 20
Chapter 1 - Introduction
The DuraCOR 312 is an ultra-small form factor (USFF) modular mission computer built around the high-
performance, yet power efficient NVIDIA® Jetson™ industrial Jetson® TX2i “supercomputer-on-a
module” integrated in a miniature rugged chassis with MIL-grade high-density connectors. Combining
powerful NVIDIA Pascal™/CUDA-core GPU signal processing with 64-bit hex-core ARMv8
heterogeneous multi-processing (HMP) for size, weight, power and cost (SWaP-C) sensitive mobile,
airborne, ground, manned and unmanned vehicle and sensor platforms, the unit integrates a massively
parallel, many-core architecture boasting one of the highest computing FLOPS-per-watt architectures on
the market. Thanks to the unit’s Pascal GPU architecture (supporting Max-Q and Max-P dynamic energy
profiles), larger memory bandwidth, and support for CANbus, the DuraCOR 312 can deliver up to twice
the performance or power efficiency of TX1-based systems together with native vehicle bus interfaces.
The unit also deliver an unparalleled modular system design, boasting multiple Mini-PCIe I/O card slots,
high-speed M.2 internal storage, removable SATA Flash SSD capabilities, and an aerospace-grade
power supply supporting 50ms power hold-up in a fan-less IP67-rated mechanical package designed for
wide temperatures and harsh shock and vibration.

Functional Description
The Parvus® DuraCOR® 312 is an ultra-small form factor (USFF) modular mission computer built around
the high-performance, yet power efficient NVIDIA® Jetson™ industrial Jetson® TX2i “supercomputer-on-
a module” integrated in a miniature rugged chassis with MIL-grade high-density connectors. Combining
powerful NVIDIA Pascal™/CUDA-core GPU signal processing with 64-bit ARMv8 heterogeneous multi-
processing (HMP) for size, weight, power and cost (SWaP-C) sensitive mobile, airborne, ground, manned
and unmanned vehicle and sensor platforms, the unit integrates a massively parallel, many-core
architecture with one of the highest computing FLOPS-per-watt architectures on the market. Thanks to
the unit’s Pascal GPU architecture (supporting Max-Q and Max-P dynamic energy profiles), larger
memory bandwidth, and support for CANbus, the DuraCOR 312 can deliver up to twice the performance
or power efficiency of TX1-based systems together with native vehicle bus interfaces. The unit also
deliver an unparalleled modular system design, boasting multiple Mini-PCIe I/O card slots, high-speed
M.2 internal storage, removable SATA Flash SSD capabilities, and an aerospace-grade power supply
supporting 50ms power hold-up in a fan-less IP67-rated mechanical package designed for wide
temperatures and harsh shock and vibration.
While the low-power DuraCOR 312 is miniature in size, this rugged COTS mission computer LRU packs
performance with six (6) ARMv8 processor cores and 256 Pascal/CUDA-core GPU along with multiple
add-on I/O and storage expansion options to support additional vetronics/avionics interfaces beyond its
already comprehensive set of base I/O (which include Ethernet, CAN, serial, USB, DIO and video ports).
The unit comes with on-board eMMC Flash and supports an optional internal M.2 SSD (NVMe/SATA), as
well as optional removable 2.5” SATA SSD storage for high capacity storage and information assurance
requirements. Like other DuraCOR models, the 312 leverages both an ecosystem of rugged COTS Mini-
PCIe modules (including MIL-STD-1553 and ARINC429 avionics databus interfaces) and Curtiss-Wright’s
responsive, cost-competitive application engineering services to deliver Modified COTS (MCOTS)
variants quickly and without a traditional NRE fee.
With military-grade ruggedization to extend Jetson TX2i operation, the DuraCOR 312 is designed to
operate reliably in extremely harsh environments, making it well suited on-board civil and military aircraft
and vehicle platforms. Comprehensive qualification testing has been performed per MIL-STD-810G, MIL-
STD-461F, MIL-STD-1275D, MIL-STD-704F and RTCA/DO-160G conditions for environmental, power
and EMI (thermal, shock, vibration, dust, water, humidity, altitude, power spikes/surges,
conducted/radiated emissions and susceptibility). In addition, optional 50-ms power hold-up capabilities
are supported for MIL-STD-704F aircraft power switch-over requirements.
