Abstract: A cache directory processing method for a multi-core processor system, and directory controllers is presented. The method includes obtaining a first directory entry corresponding to first-type storage space in shared storage space of the multi-core processor system and in a directory of the shared storage space; performing a directory entry combination operation on the first directory entry according to each directory entry in the first directory entry and according to an access type and a sharer, to form a second directory entry of the first-type storage space; and when a record quantity of the second directory entry is less than a record quantity of the first directory entry, replacing the first directory entry with the second directory entry, and using the second directory entry as a directory entry corresponding to the first-type storage space and in the directory of the shared storage space.
