Abstract: A crossbar routing arrangement is disclosed for use in a digital system having three or more buses. An associated method is also disclosed. The routing arrangement is configured for transferring a set of data received from any particular one of the buses to any other selected one of the buses and includes a control arrangement associated with each bus for dividing the set of data into at least first and second subsets of data and for adding self-routing signals to each data subset which signals identify the selected bus. A switching arrangement is configured for directing the first and second data subsets in a predetermined way responsive to the self-routing signals. The control arrangement cooperates with the switching arrangement to transfer the data subsets over physically distinct data transfer paths defined between the switching arrangement and the control arrangements.
