From this study we have found that configurable logic block's routing network is vulnerable to domain crossing errors, or TMR defeats, by even 2-bit upsets.
Performance benchmarks have been used over the years to compare different systems. These can be useful for researchers trying determine how changes technology, architecture, or compiler affect system's performance. No such standard exists systems deployed into high radiation environments, making it difficult assess whether in fabrication process, circuitry, software reliability sensitivity.

As of 2013, the gold standard for assessing radiation-hardness assurance (RHA) a system, subsystem, or component is accelerated radiation testing and/or pulsed laser testing. Fault injection tools, which include both fault simulation and emulation have become more common in last 15 years. tools use analytical methods RHA, whereas uses hardware methods. Both allow designers to augment traditional RHA techniques determine whether circuit designs, microarchitectures, components,...
Many space programs depend on cutting-edge technology to increase computational power without increasing the or weight of payload. For these types programs, component testing is necessary ensure that components do not fail while deployed. Radiation for advanced can be challenging since underlying architecture and organization might complex.

Extracting information about MCUs from SEU data sets can be a challenge without physical layout information. Many modern static-random access memory (SRAM) components interleave cells to improve the robustness of error-correcting codes (ECC) that detect and correct errors in array. Bit interleaving has also become popular with other large SRAM arrays, including field-programmable gate arrays (FPGAs). In this paper, we present technique for extracting statistically radiation test data....

Commercial off-the-shelf microcontrollers can be useful for noncritical processing on spaceborne platforms. These microprocessors inexpensive and consume small amounts of power.

We are rapidly approaching an inflection point where the conventional target of producing perfect, identical transistors that operate without upset can no longer be maintained while continuing to reduce energy per operation. With power requirements already limiting chip performance, demand upset-free would mean end scaling benefits. The big challenges in device variability and reliability driven by uncommon tails distributions, infrequent upsets, one-size-fits-all technology requirements, a...

SETA is independent technique, it was conceived work together with previously proposed data-flow aim reducing memory overheads. Thus, combined such submitted fault...
Over the past 15 years many organizations have researched use of Static-Random Access Memory (SRAM)-based Field-Programmable Gate Arrays (FPGAs) in space. Although components can provide a performance improvement over radiation-hardened processing components, random soft errors occur from naturally occurring space radiation environment. Many been developing methods for characterizing, emulating, and simulating radiation-induced events; mitigating removing computational errors; designing...
Commercially available microprocessors could be useful to the space community for noncritical computations. There are many possible components that smaller, lower-power, and less expensive than traditional radiation-hardened microprocessors. Many commercial have issues with single-event effects (SEEs), such as upsets (SEUs) transients (SETs), can cause microprocessor calculate an incorrect result or crash.
