摘要： 提出一种抵抗瞬时故障的自动编译容错恢复方法，用源码中的变量信息在指令级别进行冗余错误流裁剪，在LCC上加以实现，并获得良好的容错性能。实验结果表明，该方法仅增加0.043倍的时间损耗及0.69倍的空间损耗，在时空损耗上优于现有的其他方法。

Abstract: To counter transient fault, a fault tolerance compilation method is proposed. By using the information of variable, it cuts down the redundant logic for fault tolerance at instruction-level on LCC, which gets better performance. Experimental results show with the usage of this method, the program running time increases by only 0.043 times, and storage only 0.69 times. The overhead of it is better than that of others.
