| Abstract: | The technique of the fault recovery of a multi-processor fault tolerant system MPFTS designed by us is presented in this paper. First the structure and working flow of MPFTS is introduced in general, based on which some problems are analyzed including the possibility of the recovery of different kinds of faults, the selection of recovery time, and the goal of fault recovery. The data structure and operation process related to the fault recovery implemented by technique of exception interrupt return is discussed in detail. The special case of fault recovery of the power - on upgrade reconfiguration is analyzed. |
