Serialized bus communication and control architecture

摘要

A serial bus communication system for communication across the backplane of a node includes a control unit having a serial bus controller operable to convert between parallel signals and serialized signals. A plurality of service units each include a serial bus terminator. A serial bus includes a discrete serial channel for each service unit. The serial channel connects the serial bus terminator to the serial bus controller. The serial bus controller is operable to direct a message for a service unit on the serial bus to only the serial channel of the service unit.
