Abstract

A calculation processor for determining a digital output value (OUT) from a digital input value (IN) based on an exponent value a, the processor comprising a first calculation block (CB1), a second calculation block (CB2) and a final calculation block (CBF). The first calculation block (CB1) initializes an intermediate value and an error value depending on a position of a Most Significant Bit of a significant part of the input value. The second calculation block is configured to perform repeatedly, until an exit criterion is fulfilled, the incrementation of a counter value, the determination of a power error value based on the error value and, if the power error value is larger than or equal to an error threshold, adjustment of the intermediate value y by multiplying the intermediate value with an adaptation value and setting the error value to the power error value divided by the base value. If the power error value is smaller than the error threshold, the error value is set to the power error value. The final calculation block is configured to set the output value to the intermediate value.
