| Abstract: | Embodiments of the invention describe a Boolean circuit having a voter
circuit and a plurality of approximate circuits each based, at least in
part, on a reference circuit. The approximate circuits are each to
generate one or more output signals based on values of received input
signals. The voter circuit is to receive the one or more output signals
generated by each of the approximate circuits, and is to output one or
more signals corresponding to a majority value of the received signals.
At least some of the approximate circuits are to generate an output value
different than the reference circuit for one or more input signal values;
however, for each possible input signal value, the majority values of the
one or more output signals generated by the approximate circuits and
received by the voter circuit correspond to output signal result values
of the reference circuit. |
