主权项 1. A circuit, comprising: a switch fabric configured to have a footprint on a semiconductor surface, the footprint having four sides; a plurality of input conductors configured to conduct a plurality of channels into the switch fabric with regard to each side of the footprint, each channel having a same width in bits; a plurality of output conductors configured to conduct the plurality of channels out of the switch fabric with regard to each side of the footprint, wherein the input and output conductors for a first opposing pair of the sides are arranged in first tracks corresponding to the channels, and wherein the switch fabric includes a plurality of channel switching circuits corresponding to the channels and arranged in the footprint such that each first track spans the corresponding channel switching circuit, and wherein the input and output conductors for a second opposing pair of the sides for the footprint are arranged according to the bits in second tracks such that each second track spans across all the channel switching circuits; and wherein each channel switching circuit includes a plurality of multiplexers corresponding to each side, and wherein each side's corresponding multiplexers in each channel switching circuit are configured to drive the output conductors for the channel switching circuit's corresponding channel with a selected channel from the input conductors for the remaining sides.
