Reduced crossbar switch with minimum number of switching cells
Haruhiko Obara · Electronics Letters · 2008
The upper bound on the minimum number of switching cells in crossbar switches was investigated. It was determined that the bound is given by N(N−1), where N is the switch size. Crossbar switches were embedded into ILLIAC(N, N−1) torus networks with cell counts given by the above formula and a simple routing control algorithm for the switches is introduced.
