Some Topological Properties of Bitonic Sorters
September 1998 (vol. 47 no. 9)
pp. 983-997

Abstract—This paper proves some topological properties of bitonic sorters, which have found applications in constructing, along with banyan networks, internally nonblocking switching fabrics in future broadband networks. The states of all the sorting elements of an N×N bitonic sorter are studied for four different input sequences $\left\{ {a_i} \right\}_{i=1}^N,$$\left\{ {b_i} \right\}_{i=1}^N,$$\left\{ {c_i} \right\}_{i=1}^N,$ and $\left\{ {d_i} \right\}_{i=1}^N,$ where ai = i$-$ 1, bi = N$-$i, and the binary representations of ci and di are the bit reverse of those of ai and bi, respectively. An application of these topological properties is to help design efficient fault diagnosis procedures. We present an example for detecting and locating single faulty sorting element under a simple fault model where all sorting elements are always in the straight state or the cross state.
