Abstract
An apparatus and method for generating the square of a non-linear encoded signal having a value and a segment number includes an offset generator, a multiplier and a shifter. The offset generator receives the value of the encoded signal and adds an offset value to it thereby to generate a multiplicand. The multiplicand is squared by the multiplier and the output of the multiplier is conveyed to the shifter. The shifter shifts the output of the multiplier in accordance with the segment number thereby to generate the square of the encoded signal. The offset, multiplying and shifting steps can be performed in a single clock cycle.
