    Abstract: In an input/output multiplexer coupling a central subsystem and peripheral subsystems, a central subsystem data distributor for receiving signal groups from the central subsystem and distributing reformatted signal groups to other components of the input/output multiplexer. The central subsystem data distributor includes apparatus for reformatting data signal groups in response to control signals and includes apparatus for replacing an index number with a previously established peripheral subsystem address. Apparatus is provided to identify signal group destinations and provide activation signals for transfer of the signal groups to predetermined apparatus. The apparatus is adapted to transfer signal groups through the central subsystem data distributor in three clock cycles to ensure efficient transfer within the multiplexer.
