Abstract
Methods and systems for supporting parametric function computations in hardware circuits are proposed. In one example, a system comprises a hardware mapping table, a control circuit, and arithmetic circuits. The control circuit is configured to: in a first mode of operation, forward a set of parameters of a non-parametric function associated with an input value from the hardware mapping table to the arithmetic circuits to compute a first approximation of the non-parametric function at the input value; and in a second mode of operation, based on information indicating whether the input value is in a first input range or in a second input range from the hardware mapping table, forward a first parameter or a second parameter of a parametric function to the arithmetic circuits to compute, respectively, a second approximation or a third approximation of the parametric function at the input value.
