Title:
The method and PCD for showing a peripheral-components interface express (PCIE) joint device as the operating system which can operate on a portable computing device (PCD)
Document Type and Number:
Japanese Patent JP5916881
Kind Code:
B2
Abstract:
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.
