Abstract
Intermittent faults are an increasingly challenging difficulty in embedded and real-time systems. As process technologies shrink circuitry, it becomes increasingly susceptible to transient faults from radiation sources such as cosmic rays. Additionally, as software complexity increases, intermittent faults such as race conditions challenge software reliability. Given these motivations, research has approached the paired problems of recovering from a fault, and doing so predictably. However, most past research has been limited in focus to the predictable recovery of faults at the application-level. Examples include systems infrastructures [2] enabling application fault recovery, and scheduling theory [3] that considers periodic faults, and the impact on schedulability for recovery and re-execution of failed applications.

Application-Level Fault Tolerance as a Complement to System-Level Fault Tolerance
Special issue on embedded fault-tolerance systemsAs multiprocessor systems become more complex, their reliability will need to increase as well. In this paper we propose a novel technique which is applicable to a wide variety of distributed real-time systems, especially those exhibiting data ...
