摘要： A multi-processor system with cache sharing has a plurality of processor sub-systems and a cache coherence interconnect circuit. The processor sub-systems have a first processor sub-system and a second processor sub-system. The first processor sub-system includes at least one first processor and a first cache coupled to the at least one first processor. The second processor sub-system includes at least one second processor and a second cache coupled to the at least one second processor. The cache coherence interconnect circuit is coupled to the processor sub-systems, and used to obtain a cache line data from an evicted cache line in the first cache, and transfer the obtained cache line data to the second cache for storage.

摘要： 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 record information indicative of a first cache of the multi-processor system and first requested memory addresses that are associated with multiple first cache lines each being only available in the first cache. The second-type entry is configured to record information indicative of multiple second caches of the multi-processor system and at least a second requested memory address that is associated with a second cache line being available in each of the multiple second caches.
