    摘要: A method for performing refresh operations is disclosed. In response to a completion of a memory operation, a determination is made whether or not a refresh backlog count is greater than a first predetermined value. In a determination that the refresh backlog count is greater than the first predetermined value, a refresh operation is performed as soon as possible. In a determination that the refresh backlog count is not greater than the first predetermined value, a refresh operation is performed after a delay of an idle count value.

    摘要: A data processing system includes a processor core and a cache memory hierarchy coupled to the processor core. The cache memory hierarchy includes at least one upper level cache and a lowest level cache. A memory controller is coupled to the lowest level cache and to a system memory and includes a physical write queue from which the memory controller writes data to the system memory. The memory controller initiates accesses to the lowest level cache to place into the physical write queue selected cachelines having spatial locality with data present in the physical write queue.

    摘要: A data processing system includes a multi-level cache hierarchy including a lowest level cache, a processor core coupled to the multi-level cache hierarchy, and a memory controller coupled to the lowest level cache and to a memory bus of a system memory. The memory controller includes a physical read queue that buffers data read from the system memory via the memory bus and a physical write queue that buffers data to be written to the system memory via the memory bus. The memory controller grants priority to write operations over read operations on the memory bus based upon a number of dirty cachelines in the lowest level cache memory.
