A floating-point fused multiply-add unit embodied in an integrated circuit includes a multiplier circuit cascaded with an adder circuit to produce a result A*C+B. After removing the binder, the green compact embedded in the ceramic powder is fired in an atmosphere having an oxygen concentration higher than that in the removal procedure of the binder and thereby yields a translucent ceramic represented by Formula I: Ba{xMgyTaz}vOw, Formula II: BavOw or Formula III: Ba{xyNbz}vOw. The deck assembly further comprises an interface plate formed disposed between the deck portion and sub-structure to facilitate coupling the deck portion to the sub-structure andor to compensate for differences in thermal expansion that may exist between the deck portion and the sub-structure. Under certain conditions, however, a restricted communication module may be allowed to perform a restricted error processing operation or revert to normal unrestricted error signal processing. A pollution control device comprising a casing, a pollution control element and the mounting system disposed between the casing and the pollution control element. The second topology includes one or more internal input impedance matching components and the first topology does not include the one or more internal input impedance matching components.
