发明名称 Demand based partitioning of microprocessor caches
摘要 Associativity of a multi-core processor cache memory to a logical partition is managed and controlled by receiving a plurality of unique logical processing partition identifiers into registration of a multi-core processor, each identifier being associated with a logical processing partition on one or more cores of the multi-core processor; responsive to a shared cache memory miss, identifying a position in a cache directory for data associated with the address, the shared cache memory being multi-way set associative; associating a new cache line entry with the data and one of the registered unique logical processing partition identifiers; modifying the cache directory to reflect the association; and caching the data at the new cache line entry, wherein said shared cache memory is effectively shared on a line-by-line basis among said plurality of logical processing partitions of said multi-core processor.
