Peripheral Component Interconnect Express
Peripheral Component Interconnect Express (PCIe) is an interconnect standard that is widely used for connecting IO peripherals and accelerators to Compute System on Chips (SoCs). PCIe standard is developed and maintained by the PCI-SIG organization. Arm has published a set of requirements to be met while integrating PCIe interconnect interface into Arm-based SoCs for the server market segment. These requirements are included in the Server Base System Architecture Specification.
