Method for producing a representation of a calculation result that is linearly dependent on the square of a value

Abstract From the Canadian patent

In the transition into the logarithmic range not the , entire bit width of the result linearly dependent upon the square of the value must be considered. Rather it is , possible to scale the result of a value with x bits such that a representation with less than x bits of the result is sufficient to obtain the logarithmic representation based thereon. The effect of the scaling factor on the resulting logarithmic representation may be compensated for by adding or subtracting a correction value obtained by the logarithm function applied to the scaling factor to or from the scaled logarithmic representation without any loss of dynamics. This way, a method and an apparatus for creating …
