The invention provides a protocol reconfigurable consistency implementation method based on a configuration lookup table, and relates to the technical field of microprocessor design, and the method comprises the following steps: S1, adding a matched consistency state lookup table in consistency processing logic; S2, judging whether a consistency protocol is modified or not, if yes, writing the parameters into the lookup table, and executing S3; otherwise, directly executing S3; s3, reading hit state information of the current address request in consistency pipeline processing; s4, querying a lookup table according to the request type and hit state information of the current request; and S5, carrying out consistency operation according to the query result, and returning to the step S2. Theprotocol reconfigurable consistency implementation method based on the configuration lookup table supports correction or extension of a consistency protocol, even different consistency protocols, so as to adapt to different r
