ABSTRACT:
A system and method are provided for use in an electronic device configured to process data to perform a method of generating a fixed point approximation of a number x by first locating the most significant bit of a given number, then retrieving predetermined values from electronic data storage, where the first value is based on a first index value generated from the most significant bit and contains fixed-point representation located in a table in storage. Then, output values are generated from look-up tables that correspond to index values generated from a number of bits that immediately following the most significant bit. Finally, the final mathematic result is computed using fixed-point arithmetic logic to generate a fixed point approximation.
