Radiation
Hardening By Design (RHBD) typically refers to circuit design methodologies
on silicon. By addressing the problem from a higher point of view, that is
the application point of view, we can broaden the meaning of the term design
by relating it to a more complex context. In the application context we can
talk about Radiation Hardening By Swiss Cheese Model (RHBSCM). RHBSCM
proposes a protection based on several levels that filter the problem on
different levels and for different technical reasons. It is an interpretation
of RHBD at the application level (HW and SW) rather than an interpretation
strictly related to design on silicon. Swiss Cheese Model is sometimes called the "cumulative act
effect". · Our shielding technology is based on heavy gauge T8 aluminum
casings filled with NASAT™ (NAno Shields Avalanche Technology). This
nanotechnology optimizes the attenuation of gamma radiation and neutrons.
With this shielding technology we build RHPRD™ based on TPU (Tensor
Processing Unit) for Deep-Learning applications. · Very low frequency of the device (<100MHz) made possible by
Hardware SIMD parallelism (Neuromem® < 20MHz) and algorithmic parallelism
techniques (MYTHOS™) on radiation hardened CPUs like the BAE SYSTEMS RAD750®. · Neuromem® IP on RAD-HARD FPGAs. · Passive cooling system. · NHTMR™ (Neuromorphic Hardware Triple Modular Redundancy). We can build
customized COTS RHPRD™ with other Machine Learning acceleration technologies
available on the market if the technical features are compatible with our
shielding technologies. |
