1. A method of a digital processor for Time Of Flight sensor 2-dimensional and 3-dimensional map generation, comprising: retrieving Time Of Flight sensor fixed point data to obtain four phases of Time Of Flight fixed point raw data; computing Gray scale image array and phase differential signal arrays utilizing four phases of Time Of Flight (TOF) fixed point raw data; computing Gray image array and Amplitude image array for fixed point; converting the phase differential signal array from fixed point to floating point, wherein the converting comprises: obtaining x and y of floating division, numerator sign bit map for x sign, denominator sign bit map for y sign and absolute value x and y array; obtaining an output sign map utilizing the numerator sign bit map for x sign and the denominator sign bit map for y sign; obtaining exponents array of numerators and denominators by leading count zeros for the absolute values of x and y arrays; obtaining a mantissa array of numerators and denominators; searching an inverse mantissa lookup table, computing mantissa multiplication and exponents region calculation for utilizing with the output sign map for computing the quotients array of division output with the output sign map; applying a saturation mask and checking for denominator zero error; and generating the saturation mask and floating division out array; performing the floating point division for computing Arctan, TOF depthmap, and 3-dimensional point cloud map for Q format fixed point; and generating depthmap, 3-dimensional cloud coefficients and 3-dimensional point cloud for Q format fixed point.
