  • Out of order memory request tracking structure and technique
    Patent number: 11768686
    Abstract: In a streaming cache, multiple, dynamically sized tracking queues are employed. Request tracking information is distributed among the plural tracking queues to selectively enable out-of-order memory request returns. A dynamically controlled policy assigns pending requests to tracking queues, providing for example in-order memory returns in some contexts and/or for some traffic and out of order memory returns in other contexts and/or for other traffic.
    Type: Grant
    Filed: July 27, 2020
    Date of Patent: September 26, 2023
    Assignee: NVIDIA Corporation

  • Managing memory based on hint data generated from mapping data entries
    Patent number: 10162762
    Abstract: A data processing system 4 includes a translation lookaside buffer 6 storing mapping data entries 10 indicative of virtual-to-physical address mappings for different regions of physical addresses. A hint generator 20 coupled to the translation lookaside buffer 6 generates hint data in dependence upon the storage of mapping data entries within the translation lookaside buffer 6. The hint generator 20 tracks the loading of mapping data entries and the eviction of mapping data entries from the translation lookaside buffer 6. The hint data is supplied to a memory controller 8 which controls how data corresponding to respective different regions of physical addresses is stored within a heterogeneous memory system, e.g. the power state of different portions of the memories storing different regions, which type of memory is used to store different regions.
