摘要： A method is provided for fine-grained detection of data modification of original data by associating separate guard bits with granules of memory storing original data from which translated data has been obtained. The guard bits indicating whether the original data stored in the associated granule is protected for data coherency. The guard bits are set and cleared by special-purpose instructions. Responsive to attempting access to translated data obtained from the original data, the guard bit(s) associated with the original data is checked to determine whether the guard bit(s) fail to indicate coherency of the original data, and if so, discarding of the translated data is initiated to facilitate maintaining data coherency between the original data and the translated data.

摘要： Fine-grained detection of data modification of original data is provided by associating separate guard bits with granules of memory storing the original data from which translated data has been obtained. The guard bits facilitate indicating whether the original data stored in the associated granule is indicated as protected. The guard bits are set and cleared by special-purpose instructions. Responsive to initiating a data store operation to modify the original data, the associated guard bit(s) are checked to determine whether the original data is indicated as protected. Responsive to the checking indicating that a guard bit is set for the associated original data, the data store operation to modify the original data is faulted and the translated data is discarded, thereby facilitating data coherency between the original data and the translated data.

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.
