    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: Devices, systems, methods, and computer-readable mediums for arbitrating bus transactions on a communications bus based on health information are disclosed. Health information of master devices can be used to adjust priorities of bus transactions from master devices to meet quality of service requirements of the master devices. In one embodiment, a bus interconnect is provided and configured to communicate bus transactions from any of a plurality of master devices to slave device(s) coupled the bus interconnect. The bus interconnect is further configured to map health information for each of the plurality of master devices into virtual priority space. The bus interconnect is further configured to translate the virtual priority space into a physical priority level for each of the plurality of master devices. The bus interconnect is further configured to arbitrate bus transactions for the plurality of master devices based on physical priority level for the plurality of master devices.
