1. An arithmetic circuit, comprising: an output; a first input coupled to a sequencer circuit that provides a plurality of signals in a predetermined order, wherein the first input receives a first signal of the plurality of signals from the sequencer circuit; a second input and a third input to receive a second signal of the plurality of signals from the sequencer circuit and a third signal of the plurality of signals from the sequencer circuit; a multiplier that has a first multiplier input port, a second multiplier input port and a multiplier output port, wherein the multiplier output port is coupled to the output of the arithmetic circuit; and configuration circuitry that configures the arithmetic circuit to implement a first arithmetic function by routing the first signal and the second signal from the sequencer circuit to the first multiplier input port and the second multiplier input port in a first mode, and that configures the arithmetic circuit to implement a second arithmetic function by routing the second signal and the third signal from the sequencer circuit to the first multiplier input port and the second multiplier input port in a second mode.
