ABSTRACT:
Improved layouts for switching networks having N.multidot.log N switching circuits, and improved switches incorporating such layouts, are disclosed. An improved layout reduces grid-area requirements for Benes switching network to an area of less than 3N.sup.2 grid units. The improved layout results from positioning the various switching circuits at certain defined locations. Unlike conventional layouts of the Benes network, the switching circuits are aligned in only one direction, e.g., columns but not rows, and the links connecting switching circuits are slanted.
