Abstract-Integrity assurance of configuration data has a significant impact on microcontroller-based systems reliability. This is especially true when running applications driven by events which behavior is tightly coupled to this kind of data. This work proposes a new hybrid technique that combines hardware and software resources for detecting and recovering soft-errors in system configuration data. Our approach is based on the utilization of a common built-in microcontroller resource (timer) that works jointly with a software-based technique, which is responsible to periodically refresh the configuration data. The experiments demonstrate that non-destructive single event effects can be effectively mitigated with reduced overheads. Results show an important increase in fault coverage for SEUs and SETs, about one order of magnitude.

“…In the coherence check in Figure 4, shadow tasks t [1] and t [2] are of equal complexity and the data must match exactly. The same holds for t [3] and t [4]. When this verification is complete, a range check is performed to validate that the data in the complex and simple streams are within a preset range.…”

Abstract-Performance and time to market requirements cause many real-time designers to consider components, off the shelf (COTS) for real-time cyber-physical systems. Massive multi-core embedded processors with network-on-chip (NoC) designs to facilitate core-to-core communication are becoming common in COTS. These architectures benefit real-time scheduling, but they also pose predictability challenges. In this work, we develop a framework for Fault Observant and Correcting Real-Time Embedded design (Forte) that utilizes massive multi-core NoC designs to reduce overhead by up to an order of magnitude and to lower jitter in systems via utilizing message passing instead of shared memory as the means for intra-processor communication. Message passing, which is shown to improve the overall scalability of the system, is utilized as the basis for replication and task rejuvenation. This improves fault resilience by orders of magnitude. To our knowledge, this work is the first to systematically map real-time tasks onto massive multi-core processors with support for fault tolerance that considers NoC effects on scalability on an real hardware platform and not just in simulation.

“…Moreover, thanks to their programmability, performance and cost-effectiveness, Commercial Off-The-Shelf (COTS ) electronic components offer important capabilities and benefits in the implementation of low-cost safety-critical and high availability systems, such as micro-satellites [5,6] or avionics safety systems [7]. Nevertheless, their high sensitivity to radiation-induced effects, particularly transient faults, limit their applicability in the near future.…”

“…As software-based techniques do not require any modifications in the hardware of the microprocessor, they are particularly suitable for COTS based systems ensuring an acceptable dependability level [10][11][12]. In fact, some of these approaches have already been used in mission critical systems, including COTS microprocessors, for satellites and space missions [7].…”

Selective SWIFT-R

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.
