    Abstract: In some examples, a system on chip (SOC) comprises a network switch configured to receive a packet and to identify a flow identifier (ID) corresponding to a header of the packet. The SOC comprises a direct memory access (DMA) controller coupled to the network switch, where the DMA controller is configured to divide the packet into first and second fragments based on the flow ID and to assign a first hardware queue to the first fragment and a second hardware queue to the second fragment, and wherein the DMA controller is further configured to assign memory regions to the first and second fragments based on the first and second hardware queues. The SOC comprises a snoopy cache configured to store the first fragment to the snoopy cache or to memory based on a first cache allocation command, where the first cache allocation command is based on the memory region assigned to the first fragment, where the snoopy cache is further configured to store the second fragment to the snoopy cache or to memory based on a second cache allocation command, and where the second cache allocation command is based on the memory region assigned to the second fragment.

    Abstract: An integrated circuit is presented. The integrated circuit has a set of sensor input interfaces and an output interface. The integrated circuit further has a memory with a first and second memory locations. The integrated circuit further has a multi-chip hub module which has a transaction buffer with both a real-time and a non-real-time buffer. The multi-chip hub module has a context mapper, a re-formatter module and an error handling module. The context mapper is configured to map data to the first or second memory location. The multi-chip hub module is configured to process data through the modules and provide processed data to the output interface.

    Abstract: A peripheral proxy subsystem is placed between multiple hosts, each having a root controller, and single root I/O virtualization (SR-IOV) peripheral devices that are to be shared. The peripheral proxy subsystem provides a root controller for coupling to the endpoint of the SR-IOV peripheral device or devices and multiple endpoints for coupling to the root controllers of the hosts. The peripheral proxy subsystem maps the virtual functions of an SR-IOV peripheral device to the multiple endpoints as desired to allow the virtual functions to be allocated to the hosts. The physical function of the SR-IOV peripheral device is managed by the peripheral proxy device to provide the desired number of virtual functions. The virtual functions of the SR-IOV peripheral device are then presented to the appropriate host as a physical function or a virtual function.

    Abstract: An electronic device, comprising: a first component configured to transmit a first set of data to a second component by providing a first memory request specifying the first set of data for and an input memory address, and a transaction tracking unit coupled to a first transport interface, the transaction tracking unit configured to: receive the first memory request; transmit a second memory request that specifies at least a first portion of the first set of data, via the first transport interface, to the second component; receive a response to the second memory request from the second component; determine that the response corresponds to the second memory request; and provide, to the first component, an output response based on the received response to the second memory request.
