Zusammenfassung:Generally disclosed herein is an approach for enabling the connection of non-PCIe accelerators as PCIe devices using a Peripheral Component Interconnect Express (PCIe) abstraction layer ("PAL"). Once the operating system accesses and configures any on-SoC devices and accelerators using standard PCIe APIs, all PCIe configuration transactions may be routed to the PAL. The PAL's firmware may present the operating system with a virtual PCIe space that contains all available SoC PCIe and non-PCIe devices. The firmware of the PAL may translate PCIe configuration transactions into device-specific configuration transactions.
