Assume that words x1 and x2 are in the cache block B1 and word x3 is in the cache block B2. Initially, the block B1 is in the shared state in the caches of processors P1 and P2, and the block B2 is cached only by processor P1. Fill out the following table to state whether cache coherence miss occurs, and if yes then whether it is a true sharing miss.
