METHOD FOR PRODUCING A REPRESENTATION OF A CALCULATION RESULT THAT IS LINEARLY DEPENDENT ON THE SQUARE OF A VALUE |
摘要 |
<p>Transition to the logarithmic range does not require the entire bit range of the result that is linearly dependent on the square of the value. Rather, for a value having x bits, the result can be scaled in such a manner 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 can be cancelled by adding a correction value obtained by using the logarithmic function on the scaling factor to or subtracting it from the scaled logarithmic function without dynamic loss. The invention provides a method and a device for producing a representation of a calculation result that is linearly dependent on the square of a value, thereby allowing to carry out the calculation easily or with little hardware.</p> |
