| Abstract: | With two single-chip computers of series DVCC-51DB as main devices, the design of a single-chip computer fault tolerance system and its realization are proposed. According to the features of the single-chip computer, software-hardware has been used to solve the problem of dual computer synchronous waiting, and softwares are fitted for testing the CPU, memories and comparers. The functions with single computer output, dual computer synchronous comparative output or the output of single computer degraded from dual computers can be performed. The reliability and the mean time between faults of the system are estimated theoretically. |
