ABSTRACT:
According to at least one embodiment of the invention, an apparatus may include first, second and third circuits. The first circuit receives input data and provides a plurality of first signals asserted based on the input data. The second circuit receives the plurality of first signals and provides a plurality of second signals used to select a plurality of circuit elements. The third circuit generates a control for the second circuit using a fractional data weight of the input data, the second circuit mapping the plurality of first signals to the plurality of second signals based on the control from the third circuit.
