Abstract
A reconfigurable parallel group of identical functional units and a method for reconfiguring this parallel grouping of identical functional units upon the occurrence of a failure by shifting the contents of the failed unit and the contents of all units between the failed unit and a spare unit one unit toward the spare unit is disclosed. A paired system of input and output busses allows control lines to activate and deactivate the appropriate busses so that a constant input output interface is maintained despite the failure provoked shift. This reconfigurable parallel group can also be stacked together to form larger configurations.
