摘要

在本文中，我们提出了一种轻量级的可容错流水线处理器在冗余执行检测到错误后的恢复方案。最小回滚过程设计用于在一个周期延迟内调度基于恢复的重新执行。该方案充分利用了在线管道的工作状态来辅助恢复，从而减少了大量检查点缓冲区的恢复。

A Minimal Roll-Back Based Recovery Scheme for Fault Toleration in Pipeline Processors

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.
