Abstract

A cross link multiplexer bus comprising a plurality of cross link multiplexers and a plurality of interconnects. The plurality of cross link multiplexers has a destination port configured to receive a signal and an origin port configured to produce said signal. The plurality of interconnects has a set of interconnects coupled between a pair of adjacent cross link multiplexers. The signal is capable of being represented as a series of characters. A character is capable of being represented as a first data bit, a second data bit, and a control bit. A first interconnect is configured to convey the first data bit. A second interconnect is configured to convey the second data bit. A third interconnect is configured to convey the control bit. The third interconnect is positioned substantially between the first interconnect and the second interconnect.
