Abstract
A data switchincludes a switching engine, and input/output interfaceswhich each connect the switching engineto one of a number of channels. The input/output interfacesand the switching engineare each made up of a number of modules (PHY, MAC_RX, RX, MAC_TX, TX, PBM, ARL, QM). Some or all of the modules have a logic circuit for turning them on when they are required to process data packets passing through the circuit, and a logic circuit is provided for turning them off when they are no longer required. In this way the power requirements of the switchare reduced.
