摘要：The capacity of switching elements, for instance 8x8 elements, is expanded, to originate single-stage elements with greater capacity (16x16 or 32x32), by arranging an even plurality of such elements in an output substage and by placing upstream of the output substage at least a first input substage comprising a corresponding even plurality of the switching elements. The even and, respectively, the odd outputs of the elements of the input substage are connected in an orderly manner to the inputs of the switching elements of the output substage. A routing management logic to obtain single-stage elements is also provided within each individual switching element.
