Abstract
A data processing apparatus is provided to convert a plurality of signed digits to an output value. Receiver circuitry receives, at each of a plurality of iterations, one of the plurality of signed digits, each of the signed digits comprising a number of bits dependent on a radix. The signed digits being used to form an unrounded output value followed by zero or more extra bits. Adjustment circuitry adjusts a least-significant digit of the unrounded output value to produce an incremented unrounded output value after the plurality of iterations. Rounding circuitry selects from among the unrounded output value and the incremented unrounded output value to produce the output value. The adjustment circuitry is adapted, when a value of a position of a least-significant bit of the unrounded output value is greater than or equal to the radix divided by two, to adjust a subset of the digits of the unrounded output value.
