摘要:
In exemplary aspects of managing the ejection of entries of a coherence directory cache, the directory cache includes directory cache entries that can store copies of respective directory entries from a coherency directory. Each of the directory cache entries is configured to include state and ownership information of respective memory blocks. Information is stored, which indicates if memory blocks are in an active state within a memory region of a memory. A request is received and includes a memory address of a first memory block. Based on the memory address in the request, a cache hit in the directory cache is detected. The request is determined to be a request to change the state of the first memory block to an invalid state. The ejection of a directory cache entry corresponding to the first memory block is managed based on ejection policy rules.
