    摘要: In one embodiment, the present invention includes a method for receiving a cache access request for data present in a lower-level cache line of a lower-level cache, and sending recency information regarding the lower-level cache line to a higher-level cache. The higher-level cache may be inclusive with the lower-level cache and may update age data associated with the cache line, thus reducing the likelihood of eviction of the cache line. Other embodiments are described and claimed.

    摘要: A method is disclosed. The method includes scheduling a load operation at least twice the size of a maximum access supported by a memory device, dividing the load operation into a plurality of separate load operation segments having a size equivalent to the maximum access supported by the memory device, and performing each of the plurality of load operation segments. A further method is disclosed where a temporary register is used to minimize the number of memory accesses to support unaligned accesses.

    摘要: In one embodiment, the present invention includes a processor having multiple cores and an uncore. The uncore may include a microcode read only memory to store microcode to be executed in the cores (that themselves do not include such memory). The cores can include a microcode sequencer to sequence a plurality of micro-instructions (uops) of microcode that corresponds to a macro-instruction to be executed in an execution unit of the corresponding core. Other embodiments are described and claimed.

    摘要: Embodiments of the present invention relate to cache coherency. In an embodiment of the invention, a cache includes one or more cache lines. A store pipeline may retrieve a tag associated with one of the cache lines. The data associated with the cache line may not retrieved and the cache line may be updated if, based on the tag, the cache line is determined to be in a modified or exclusive state.

    摘要: Embodiments of the present invention relate to a memory management scheme and apparatus that enables efficient cache memory management. The method includes writing an entry to a store buffer at execute time; determining if the entry's address is in a first-level cache associated with the store buffer before retirement; and setting a status bit associated with the entry in said store buffer, if the address is in the cache in either exclusive or modified state. The method further includes immediately writing the entry to the first-level cache at or after retirement when the status bit is set; and de-allocating the entry from said store buffer at retirement. The method further may comprise resetting the status bit if the cacheline is allocated over or is evicted from the cache before the store buffer entry attempts to write to the cache.
