On-the-fly Range Reduction.

(eng) In several cases, the input argument of an elementary function evaluation is given bit-serially, most significant bit first. We suggest a solution for performing the first step of the evaluation (namely, the range reduction) \emph{on the fly}: the computation is overlapped with the reception of the input bits. This algorithm can be used for the trigonometric functions $\sin$, $\cos$, $\tan$ as well as for the exponential function
