Abstract:
A cache coherence management method, a node controller, and a multiprocessor system that includes a first table, a second table, a node controller, and at least two nodes, where the node controller determines, in the first table according to address information of data, a first entry, where the first entry includes a first field and a second field. The first field records an occupation status of the data, the second field indicates a node that occupies the data exclusively when the first field includes an exclusive state, and the node controller determines a second entry in the second table according to the address information of the data and the second field when the first field includes a shared state, where the second entry includes a third field, and the third field indicates nodes that share the data.
