1. A digital crossbar switch for switching data between an internal data bus and one or more input/output data buses, comprising:

  • a plurality of multiplexer logic units;

    an m-bit internal data bus coupled to each of said multiplexer logic units where m is an integer;

    a plurality of n-bit input/output data buses, one connected to each of said multiplexer logic units where n is an integer;

    a m/n to 1 multiplexer, where m/n is an integer, each multiplexer logic unit having an input coupled to said internal data bus and an output coupled to a corresponding one of said input/output data buses and operative in response to a configuration control signal to switch a selected n-bits of data from said internal data bus to the corresponding input/output data bus; and

    memory storage for configuration control signals coupled to said m/n to 1 multiplexer.
