Zusammenfassung:A snoop filter for a multi-processor system has a storage device and a control circuit. The control circuit manages at least a first-type entry and at least a second-type entry stored in the storage device. The first-type entry is configured to store information of multiple cache lists of the multi-processor system, and the cache lists only exist in high-speed caches and are associated with memory addresses. The second-type entry is configured to store information of at least one cache list of the multi-processor system, and the cache list only exists in multiple high-speed caches and are associated with memory addresses.
