    摘要： Dynamic allocation of cache buffer slots includes receiving a request to perform an operation that requires a storage buffer slot, the storage buffer slot residing in a level of storage. The dynamic allocation of cache buffer slots also includes determining availability of the storage buffer slot for the cache index as specified by the request. Upon determining the storage buffer slot is not available, the dynamic allocation of cache buffer slots includes evicting data stored in the storage buffer slot, and reserving the storage buffer slot for data associated with the request.

    摘要： A method that includes providing LRU selection logic which controllably pass requests for access to computer system resources to a shared resource via a first level and a second level, determining whether a request in a request group is active, presenting the request to LRU selection logic at the first level, when it is determined that the request is active, determining whether the request is a LRU request of the request group at the first level, forwarding the request to the second level when it is determined that the request is the LRU request of the request group, comparing the request to an LRU request from each of the request groups at the second level to determine whether the request is a LRU request of the plurality of request groups, and selecting the LRU request of the plurality of request groups to access the shared resource.
