A reconfigurable cable/pod unit replaces the cable/pod unit coupling an emulation unit and a target processor. The reconfigurable cable/pod unit includes the discrete logic elements, a programmable unit and interface logic. The programmable unit and the interface unit permit the pod unit to assign conductors to the coupled cable. The interface unit includes storage and other logic elements that compensate for the differences in clock speeds and in rates of data exchange between the emulation unit and the target processor. No changes are necessary in the emulation unit to use the reconfigurable cable/pod unit. The reconfigurable cable pod unit permits, by changing the programming in the programmable unit, to operate in selectable modes, to provide a selectable interface to the target processor, to implement changes and upgrades in the testing procedures, and to test different types of target processors.
