“…The resources omitted during the fault injection campaigns (e.g. pipeline registers) could likewise lead to the same result, as suggested by other authors [7]. Secondly, the individuals showing the best fault coverage estimations (O0, MaxMWTF and P.Pareto), as expected, presented a lower dynamic cross-section than the others.…”

“…Even though the results suggested that this flag provided better overall system behavior, in general, no clear relation was established between the standard optimizations, applications, and reliability enhancements. A similar conclusion can be found in [7], a study that concerned an ARM processor and emulated fault injection on the real hardware. When compared with the crosssections obtained in heavy-ion experiments, the results showed different trends.…”

A method is presented for automated improvement of embedded application reliability. The compilation process is guided using Genetic Algorithms and a Multi-Objective Optimization Approach (MOOGA). Even though modern compilers are not designed to generate reliable builds, they can be tuned to obtain compilations that improve their reliability, through simultaneous optimization of their fault coverage, execution time, and memory size. Experiments show that relevant reliability improvements can be obtained from efficient exploration of the compilation solutions space. Fault-injection simulation campaigns are performed to assess our proposal against different benchmarks and the results are assessed against a real ARM-based System on Chip under proton irradiation.

“…rough fault injection and heavy ion experiments, Filipe studied the impact of register file errors on the reliability of modern embedded microprocessors. In addition, Filipe also evaluated how different levels of compiler optimization modify the use and failure probability of processor register files, but there is no data support for this experiment [6]. Sato et al introduced the design and experimental results of a fast singleflux quantum (RSFQ) bit serial microprocessor with small embedded random access memory (RAM) and minimum instruction set CORE e2h.…”

Numbers no longer only have a purely mathematical meaning but a code that can change the way of human existence, cognition, and thinking, and a basic element to convey information. With the advent of the “Internet+” era, the development of digital media technology, digitization, and informatization has been integrated into all walks of life and has a vital impact on the development of all walks of life, and also brought about the ideological change of fine arts. Nowadays, the digitization of fine arts is a new product of the computer age, and how to protect it is also an important topic. The continuous development of wireless mobile communications has promoted the rapid development of microprocessors. In this article, we will study the protective effect of microprocessors on the digitization of fine arts. This paper designs a microprocessor-based art digital protection website, with the purpose of preserving, inheriting, and disseminating folk art works through the website. The result of the experiment shows that the sampling rate of the microprocessor has reached the requirement of the signal. The largest number of users of the folk art digital website is young people aged 18–29, accounting for 32%; the highest average score for the website is those over 59 years old, with an average score of 90.

“…For instance, the relaxation of some constraints, such as permitting few overheads throughout the execution time of an application, can only be tolerated when a significant improvement in reliability or resource availability compensates the overhead incorporated in the system. However, costly irradiation campaigns are still necessary to ensure the correctness of the solution, because in most cases there is no clear correlation between simulation and irradiation results [27]. The main problem is the way in which real irradiation results can be accurately predicted with simulated fault injection campaigns on complex devices.…”

A mathematical model is described to predict microprocessor fault tolerance under radiation. The model is empirically trained by combining data from simulated faultinjection campaigns, and radiation experiments, both with protons (at the CNA facilities, Seville, Spain) and with neutrons (at the LANSCE Weapons Neutron Research facility at Los Alamos, USA). The sensitivity to soft errors of different blocks of commercial processors is identified to estimate the reliability of a set of programs that had previously been optimized, hardened, or both. The results showed a standard error under 0.1, in the case of the ARM processor, and 0.12, in the case of the MSP430 microcontroller.
