A register renaming table recovery method for use in a processor includes the following steps. Firstly, a flushing operation is performed on a renaming-history table according to a flushed ID. Then, a first renamed ID corresponding to a first register is acquired from an unflushed row of the renaming-history table that is immediately adjacent to the flushed ID. If the first renamed ID is occupied, a register renaming table is updated to rename the first register according to the first renamed ID. Whereas, if the first renamed ID is not occupied, the register renaming table is updated to keep the first register unrenamed.
