Abstract
A square estimator computes an estimate of the square of an input number. The input number preferably is provided to combinational logic that logically manipulates the bits of the input number to generate an estimate of the square of the input number. The level of accuracy of the square generator can be programmed or predetermined by including or enabling various term generator logic units. Each term generator logic unit produces an output value that, when added to all of the other output values from the other term generators, provides an estimate of the square of the input number. Additionally, negative correction logic can also be incorporated into the square estimator for producing a negative correction value that when added to the estimate values from the various term generators, permits the square estimator to estimate the square of negative numbers as well as positive numbers.
