Compiler-assisted debugging and multiple instruction retry
… processor failure, especially when the error detection latency is only a few cycles. Speculative execution can achieve significant speedup for superscalar architectures by utilizing instruction retry to roll back the computation above mispredicted branches. Debugging is another field that can …

Protecting vehicles from cyberattacks: context aware AI-based intrusion detection for vehicle CAN bus security.
… artificial intelligence (AI)-based intrusion detection systems (IDSs) can detect these attacks, achieving higher detection rates in near-real-time poses challenges. This research aims to enhance in-vehicle network (IVN) attack detection by developing a deployable AI-based IDS. First, a …

Low-cost error detection through high-level synthesis
… performance impact. Leveraging a mean error detection latency of 12.75 cycles (4150x faster than end result check) for soft errors, we also explore a rollback recovery method with an additional area cost of 28.0%, observing a 175x increase in reliability against soft errors. Another solution …

Concurrent detection of transient faults in microprocessors
… critical real-time application areas. Concurrent detection of these errors is necessary for real-time operation. Most existing fault tolerance schemes either use redundancy to mask effects of transient faults or monitor the system for abnormal operations and then perform recovery operation. …

Toward high-level synthesis of reliable circuits through low-cost modulo shadow datapaths
… performance impact. Leveraging a mean error detection latency of 13.92 and 14.96 cycles, with both mod-3 and mod-5 units respectively (2554x faster than end result check) for soft errors, we also explore a rollback recovery method with an additional area cost of 28.0% for both cases, …

Modeling the effect of trend information on human failure detection and diagnosis in spacecraft systems
… on human decision making performance. Decision latency and accuracy were examined as performance metrics. To elicit information regarding the subjects' decision making process, the Lens model was used to gather metrics on achievement and decision consistency. The experimental results showed that …

Practical systems for overcoming processor imperfections
… to software developers. By combining the low detection latency of hardware-implemented detectors with lightweight, formally verified software recovery routines, the SoftPatch maintains the illusion of a perfect proces- sor in the face of processor imperfections. SoftPatch uniquely leverages …

Robust and reliable hardware accelerator design through high-level synthesis
… validation, and post-deployment error detection. Our solution for rapid pre-silicon debugging of accelerator designs is hybrid tracing: comparing a datapath-level trace of hardware execution with a reference software implementation at a fine temporal and spatial granularity to detect …

Providing application-aware reliability through OS/hypervisor-level techniques
… modules for providing application-aware error detection and recovery. The purpose of the RMK is to provide an automatic approach for low-latency crash/hang detection and rapid recovery via checkpoint. We first demonstrate how the RMK works in a native system and then enhance the RMK to work in …

Data Collection, Dissemination, and Security in Vehicular Ad Hoc Network
… topics emerge, such as traffic-congestion detection and road-bump detection. After data are collected and processed, they are disseminated, such that other vehicles can collaboratively sense the road and traffic status. This motivates the need for data dissemination algorithms in a VANET. …
