    Abstract: Systems, methods, and computer program products are disclosed for reducing latency in a system that includes one or more processing devices, a system memory, and a cache memory. A pre-fetch command that identifies requested data is received from a requestor device. The requested data is pre-fetched from the system memory into the cache memory in response to the pre-fetch command. The data pre-fetch may be preceded by a pre-fetch of an address translation. A data access request corresponding to the pre-fetch command is then received, and in response to the data access request the data is provided from the cache memory to the requestor device.

    Abstract: Providing memory management unit (MMU) partitioned translation caches, and related apparatuses, methods, and computer-readable media. In this regard, in one aspect, an apparatus comprising an MMU is provided. The MMU comprises a translation cache providing a plurality of translation cache entries defining address translation mappings. The MMU further comprises a partition descriptor table providing a plurality of partition descriptors defining a corresponding plurality of partitions each comprising one or more translation cache entries of the plurality of translation cache entries. The MMU also comprises a partition translation circuit configured to receive a memory access request from a requestor. The partition translation circuit is further configured to determine a translation cache partition identifier (TCPID) of the memory access request, identify one or more partitions of the plurality of partitions based on the TCPID, and perform the memory access request on a translation cache entry of the one or more partitions.

    Abstract: A method and system for dynamic control of shared memory resources within a portable computing device (“PCD”) are disclosed. A limit request of an unacceptable deadline miss (“UDM”) engine of the portable computing device may be determined with a limit request sensor within the UDM element. Next, a memory management unit modifies a shared memory resource arbitration policy in view of the limit request. By modifying the shared memory resource arbitration policy, the memory management unit may smartly allocate resources to service translation requests separately queued based on having emanated from either a flooding engine or a non-flooding engine.

    Abstract: The aspects include systems and methods of managing virtual memory page shareability. A processor or memory management unit may set in a page table an indication that a virtual memory page is not shareable with an outer domain processor. The processor or memory management unit may monitor for when the outer domain processor attempts or has attempted to access the virtual memory page. In response to the outer domain processor attempting to access the virtual memory page, the processor may perform a virtual memory page operation on the virtual memory page.
