The invention discloses an efficient fetch production line supporting synchronous EDAC inspection. The procedure comprises the steps: (1) program address generate (AG), (2) program address send (AS), wherein the AS is used for receiving returned data from a Tag body, conducting hitting judgment, conducting Tag body accompany computation, judging whether errors occur in the Tag body and correcting the first stage errors, the production line is stopped when errors occur in the Tag body information which is received by the AS, the AS corrects the errors, then conducts the hitting judgment and judges whether to read a next stage memorizer or not, (3) program access ready wait (WT), wherein the WT is used for waiting for an instruction packet returned from a data body or the next memorizer, making judgment, conducting data body accompany computation, judging whether errors occur in the data body, correcting the first stage error and writing in the EDAC codes of the Tag body and the data body, and (4) program fetch packet receive (RE). The efficient fetch production line supporting synchronous EDAC inspection has the advantages of being efficient, strong in error correcting capability, little in hardware cost, transparent to a programmer and the like.
