Abstract
A partitioned switch having distributed clocks includes a global matrix switch and one or more self-contained mini-switches. The mini-switches each contain ports connected via a local matrix switch. Communication between ports located in the same mini-switch is performed synchronously and in parallel via the local matrix switch. Communication between ports located in different mini-switches is performed asynchronously and serially via the global matrix switch. The mini-switches control the global matrix switch by serially and asynchronously sending control information to the global matrix switch.
