Abstract
Embodiments of the present invention provide functionality, within a storage-shelf-router integrated circuit, an I/O-controller integrated circuit, or other integrated-circuit implementations of complex electronic devices, for interconnecting all possible pairs of communications ports, a first member of each pair selected from a first set of communications ports and a second member of each pair selected from a second set of communications ports. Embodiments of the present invention employ a time-division-multiplexed global shared memory in order to provide full cross-communications between two or more sets of serial-communications ports, using modest controlling clock rates and wide data-transfer channels.
