Abstract

As embedded and real-time systems increase in complexity, and as chip process technologies continually decrease feature size, transient faults increasingly threaten system failure. This paper introduces C3, an system to tolerate system-level faults (e.g. in the scheduler). When considering predictable recovery of system-level components, we introduce recovery interference, a side-effect of system-level recovery that causes possibly unbounded priority inversion. We discuss an interface-driven recovery technique that is effective, efficient, and uses on-demand recovery to avoid recovery interference.
