摘要
A method of constructing a Share-F state in a local domain of a multi-level cache coherency domain system, includes: 1) when it is requested to access S state remote data at the same address, determining an accessed data copy by inquiring a remote proxy directory RDIR, and determining whether the data copy is in an inter-node S state and an intra-node F state; 2) directly forwarding the data copy to a requester, and recording the data copy of the current requester as an inter-node Cache coherency domain S state and an intra-node Cache coherency domain F state; and 3) after data forwarding is completed, recording, in a remote data directory RDIR, an intra-node processor losing an F permission state as the inter-node Cache coherency domain S state and the intra-node Cache coherency domain F state.
