%X FPGA has been used widely now, but the architecture of TMR(triple module redundancy) can not make full use of FPGA. This paper proposed a fault-tolerant scheduling algorithm of hardware real-time tasks based on primary/slave copy. By scheduled backwards, the salve copy executed as late as possible before its deadline. So that the primary copy had no overlap or as small overlap as possible with the slave copy on the executing time. When the primary copy executed successfully, released the slave copy. The result of experiment demonstrates that the method can use the FPGA more efficiently than TMR and the accept ratio of hardware tasks increases.
