Abstract
A data processing system is implemented with a backup PCI Express system, which is able to take over as the primary PCI Express system for ensuring that the endpoint devices continue to function in a desired manner when the initial primary root complex is no longer functioning correctly. Each of the endpoint devices is coupled to the initial primary root complex and a backup root complex through a multiplexer. When a failure of the initial primary root complex is detected, the backup root complex signals each multiplexer to switch the communication of data from occurring between the initial primary root complex and the endpoint devices to then occur between the backup root complex and the endpoint devices.
