Abstract
Many Peripheral Component Interconnect Express (PCIE) lanes are available between a root complex host and peripherals inserted into slots. Each PCIE lane is a bi-directional serial bus, with a transmit differential pair and a receive differential pair of data lines. Some lanes are directly connected from the root complex host to each slot. Each slot is driven by a different port and a different direct physical layer on the host. Other lanes are configurable and can be driven by any port and use a configurable physical layer on the host. These configurable lanes pass through an external switch or crossbar that connects the lanes from the host to one or more of the slots. The direct-connect lanes can be the first lanes to a slot while the configurable lanes are the higher-numbered lanes.
