IMPLEMENTATION OF SWITCHES IN A COMMUNICATION NETWORK

摘要

A routing device such as either a 1:N demultiplexer or N:1 multiplexer can provide a power dissipation proportional to log2(N) by augmenting a conventional data demultiplexer/multiplexer with additional control circuitry. The control circuit ensures that control signals that trigger configuration of individual demultiplexer/multiplexer elements are propagated only along a data transmission path. Logic components of the control circuitry enable the multiplexers to be self-configuring and to prevent multiplexers from switching to elements with empty data buffers.
