Abstract: A data processing apparatus is provided that includes communication circuitry to transmit an interconnect message to a root port using a physical address mapped to the root port. Translation circuitry encapsulates, within the interconnect message to the root port, a Peripheral Component Interconnect Express (PCIe) message to a destination, the PCIe message having routing information encoded as a PCIe bus number associated with the destination.
