Abstract
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.
