The paper surveys various softwarefaulttolerance techniques and methodologies.
本文主要给出现有主流软件容错技术的一个综述。

Traditional softwarefaulttolerance USES a great deal of branch instructions to detect errors, thus brings great overhead in both performance and power dissipation.
传统的软件容错技术频繁使用和比较分支指令检测错误，带来了巨大的性能和功耗的开销。
