ABSTRACT:
A nonlinear conversion system using precision mapping and the method thereof are described. The system includes a source value converter, a mapping table unit, a recovering parameter computing unit, and an output computing unit. The method includes the steps of: receiving an input value; converting the input value into a source value; mapping the source value to a destination value in a limited domain for restricting the calculation within a destination domain; establishing a mapping table by directly selecting a precision according to the destination domain and inverse-mapping back to a source domain; and outputting the destination value according to the mapping table, combining the destination value with a recovering parameter for recovering an output value produced by the nonlinear conversion of the input value.
