In a portable computing device having a system-on-chip (SoC) Acorn RISC Machine (ARM)-based resource architecture, a peripheral component interconnect express (PCIe) bus is used to insert PCIe device memory into system memory absent a PCIe driver. During a PCIe initialization, the contents of PCIe base address registers (BARs) are mapped or otherwise updated to coincide with values assigned to the PCIe device in the advanced configuration and power interface (ACPI) tables.

Method and a portable computing device (PCD) for exposing a peripheral component interface express (PCIE) coupled device to an operating system operable on the PCD

Systems and methodologies are described that facilitate enhanced data service functionality for data services operating in a multi-processor computing environment. As described herein, respective processors and/or other components can be utilized to form a Smart Peripheral Subsystem (SPS). As further described herein, the SPS can operate in association with a modem processor and an application processor at a mobile computing device in order to reduce loading at the application processor and improve memory usage efficiency. In the case of a mobile computing device sharing a network connection with a tethered computing device, the SPS can couple a modem interface associated with the mobile computing device and an interface through which the disparate computing device is tethered to the mobile computing device such that operations such as Layer 2 (L2) framing and/or de-framing, Network Address Translation (NAT), or the like can be offloaded to the SPS under various circumstances.
