Abstract

In data processing systems that use a snoopy based cache coherence protocol and which contain a read only cache memory with a bounded range of addresses, a cache line hit is detected by assuming that, if an address contained in a request falls within the bounded range, the cache line is present in the cache memory for snoop results. This is equivalent to assuming that the cache line is marked as shared when it might not be so marked.
