“…These techniques combine software redundancy with additional hardware support [42][43][44][45][46]. In this context, the S-SWIFT-R technique here proposed can be used as a part of a more complex hybrid technique, or as a component of a cross-layer protection strategy.…”

Commercial off-the-shelf microprocessors are the core of low-cost embedded systems due to their programmability and cost-effectiveness. Recent advances in electronic technologies have allowed remarkable improvements in their performance. However, they have also made microprocessors more susceptible to transient faults induced by radiation. These non-destructive events (soft errors), may cause a microprocessor to produce a wrong computation result or lose control of a system with catastrophic consequences. Therefore, soft error mitigation has become a compulsory requirement for an increasing number of applications, which operate from the space to the ground level. In this context, this paper uses the concept of selective hardening, which is aimed to design reduced-overhead and flexible mitigation techniques. Following this concept, a novel flexible version of the software-based fault recovery technique known as SWIFT-R is proposed. Our approach makes possible to select different registers subsets from the microprocessor register file to be protected on software. Thus, design space is enriched with a wide spectrum of new partially protected versions, which offer more flexibility to designers. This permits to find the best tradeoffs between performance, code size, and fault coverage. Three case studies have been developed to show the applicability and flexibility of the proposal.

“…Most of the works targeting on the radiation fault tolerance propose solutions to Single-Event Effects (SEE) [3], [4], [5], [6], [7], therefore focusing on the types of radiations encountered in space. Although Total Ionizing Dose (TID) effects on low-level devices have been reviewed in literature [8], [9], few works focused on the solutions to provide reliability on higher levels.…”

“…To deal with such environments, many proposals have been employed in the state-of-the-art: (i) hardware enhancement to provide fault tolerance for circuits [6], [7]; (ii) software fault-tolerant techniques [4], [5] and (iii) a mix of different proposals [3]. To the best of the authors' knowledge, there is no such system or framework which can provide the flexibility to combine such different techniques.…”

Robots can be used to deal with hazardous materials like nuclear waste. Unfortunately, electronic components are also susceptible to radiation effects. Current proposals to tackle this issue solve only parts of the problems for the specific scenarios and the specific types of radiation. At the same time, current computational devices should provide run-time capabilities to monitor and adapt to different situations. In this paper, we target a possible solution presenting a framework which provides the flexibility to employ fault-tolerant techniques on distributed systems. As proof of concept, we target a fault-tolerant technique to extend the operating time of systems in harsh environments. Results show a very low overhead, of few microseconds, to execute a majority voter with replicated tasks.

“…Considering that the networked control system is software-intensive, the transient fault detection in NCS needs a systematic approach containing the fault detection in embedded realization platforms. For detecting fault in embedded systems, Pinello et al [17] discussed the execution platform faults and proposed a fault-detection and tolerance approach, Li and Hong [18] discussed the control flow and data flow model for fault detection in a space control system, and Bernardi et al [19] discussed the fault detection in a software-implemented approach. Some traditional fault detection architectures (i.e., FTA and CCS) focused on how to detect the source of fault.…”

Transient faults appear unpredictablly and frequently in networked control systems (NCSs), which directly affect the safety of system. However, they can not be accurately identified due to various kinds of causes, so the detection of them needs more systematic and comprehensive system knowledge. Hence, a hierarchical and systematic detection approach based on function, behavior, and structure (FBS) models is proposed in this paper. The FBS models are established according to systematic knowledge of NCSs. And the transient faults are excavated in node level and system level, in which parameter match and model-based detections are employed. Moreover, the key implementation aspects of the proposed approach in NCSs are detailed on parameterization of FBS models, criteria, and feature parameters of faults, fault monitoring, fault detection, and real-time scheduling considering fault detection. At last, a simulation platform of a networked control liquid mixer system is described by Architecture Analysis and Design Language (AADL), and a transient fault is injected before the sample task in the node for fault detection. The simulation results show that the faults are exposed in the gradual detection hierarchies and the effectiveness of the detection scheme is quite promising.
