A digital crossbar switch for switching data from an input/output data bus to an internal data bus and to the same or another input/output data bus which includes 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 digital crossbar switch for switching data from an input/output data bus to an internal data bus and to the same or another input/output data bus which includes 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, and a plurality of n-bit input/output data buses one connected to each of the multiplexer logic units were n is an integer. The switch further includes an m/n to 1 multiplexer, where m/n is an integer, in each multiplexer logic unit. The m/n to 1 multiplexer has an input control to the internal data bus and an output coupled to a corresponding one of the input/output data buses and is operative in response to a configuration control signal to switch a selected n-bits of data from the internal data bus to the corresponding input/output data bus. A memory storage for storing configuration control signals is coupled to the m/n to 1 multiplexer.
