| Abstract: | In this paper, transient fault tolerance technology is a new approach to improvereliability based on fault-masking and fault recovery ideas. The fault tolerance model and lev-els of digital system are proposed. Based on the missile-born computer, the transient fault isdetected and dealt with on-line in order to decrease or eliminate the effect on the control-sys-tem. |
