Abstract:
In a digital system including at least three buses, a routing arrangement for transferring a set of data received from any particular one of the buses to any other selected one of the buses, said routing arrangement comprising:a) a control arrangement associated with each bus for dividing said 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;b) a switching arrangement for directing the first and second data subsets in a predetermined way responsive to said self-routing signals;c) first and second input data transfer paths connecting the control arrangement associated with the particular bus to the switching arrangement such that said first data subset can be transferred from the particular bus to the switching arrangement using said first input data transfer path and said second data subset can be transferred from the particular bus to the switching arrangement using said second input data transfer path; andd) first and second output data transfer paths connecting the switching arrangement with the control arrangement associated with the selected bus such that said first data subset can be transferred from said switching arrangement to said selected bus using said first output data transfer path and so that said second data subset can be transferred from the particular bus to the switching arrangement using said second output data transfer path, said switching arrangement directing the first and second data subsets in said predetermined way by transferring the first and second data subsets from said first and second input data transfer paths to said first and second output data transfer paths, respectively.
