Abstract
A scalable selector and method for a data processing system provides a multiple-bit, multiple bus selector logic for controling data routing and allowing dataflow to be connected and reconnected without change to control logic. The scalable selector logic includes a data selector controlled by the input controls as could accommodate controls from the Prior Art, as well providing an additional Orthogonality Checker to monitor for the condition where more than one control signal is active, and additional Data Valid logic to determine whether any of the input data buses has been selected to the output. The scalable selectors can be used in a switching network where these additional outputs operate as network controls allowing for the selection of buses in a switch network with orthogonality checking and data valid generation. The selectors also allow for swapping of data ports for timing and function sharing without impacting existing external control logic.
