ABSTRACT:
A system is disclosed for switching a selected one out of a plurality of rule groups to an inference device which operates on applied input data using the selected rule group. A starting rule group decision unit receives the input data and decides on a starting rule group to be used by the inference device on the received input data. During operation, the selecting unit may designate another rule group to be activated for use by the inference device. The plurality of rule groups are preferably associated with respective rule group processors each having a plurality of rule evaluation units, the starting rule group decision unit decides on one of the rule group processors used in the inference device, and the selecting unit includes a plurality of switching gates respectively assigned to the rule group processors so that a rule group processor is selected for use by activating its assigned switching gates.
