Claim 26:
27. The method as claimed in claim 26, wherein:
the first processor further includes a second core, and the second core includes a second in-core cache module;
each snoop request is further transferred to the second in-core cache module through the first snoop filter;
in response to each snoop request, the second in-core cache module searches itself to determine which cache lines within the second in-core cache module match the tag carried on the snoop request, wherein: if a matched cache line has been modified, the second in-core cache module writes back the matched cache line to the system memory; and, whether modified or not, all matched cache lines within the second in-core cache module are invalidated.
