Abstract:
1. A method for configuring a routing device comprising a plurality of switching elements and a demultiplexer that can be configured to form a routing path through the routing device, the method comprising: receiving a control signal into the routing device; propagating the control signal into the routing path, wherein the routing device comprises at least 2N−1 switching elements, wherein N comprises one of a number of input channels and a number of output channels, wherein propagating the control signal comprises propagating the control signal to a number of the switching elements that is proportional to log configuring the switching elements on the routing path that receive the control signal; receiving a configuration phase signal that places the demultiplexer in a configuration phase; during the configuration phase, selecting one of a first routing path and a second routing path; configuring the selected one of the first routing path and the second routing path as an output routing path; and outputting the configuration phase signal on the output routing path.
