Abstract
In an embodiment, a fused multiply-add (FMA) circuit is configured to receive a plurality of input data values to perform an FMA instruction on the input data values. The circuit includes a multiplier unit and an adder unit coupled to an output of the multiplier unit, and a control logic to receive the input data values and to reduce switching activity and thus reduce power consumption of one or more components of the circuit based on a value of one or more of the input data values. Other embodiments are described and claimed.
