Abstract :
In this paper, we proposed a light-weighted recovery scheme for fault tolerable pipeline processors after error has been detected by redundant executions. A minimal rolling back procedure is designed to schedule the re-execution based recovery in a one-cycle delay. This scheme makes full use of in-fly pipeline working status to aid the recovery, which relieves the recovery from a large checkpoint buffer.
