摘要：A data processing apparatus is provided to convert a plurality of signed digitsto an output value. Receiver circuitry receives, at each of a plurality of iterations, one ofthe plurality of signed digits, each of the signed digits comprising a number of bitsdependent 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 digitof the unrounded output value to produce an incremented unrounded output value afterthe plurality of iterations. Rounding circuitry selects from among the unrounded outputvalue and the incremented unrounded output value to produce the output value. Theadjustment circuitry is adapted, when a value of a position of a least-significant bit of theunrounded output value is greater than or equal to the radix divided by two, to adjust asubset of the digits of the unrounded output value.
