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 receive...http://www.google.de/patents/US8037114?utm_source=gb-gplus-sharePatent US8037114 - Method for creating a representation of a calculation result linearly dependent upon a square of a value
