DATA PROCESSING APPARATUS AND METHOD

摘要

Processing circuitry is provided for performing a shift-round-and-accumulate operation. The operation comprises shifting an input value to generate a shifted value using shifting circuitry, adding the shifted value to an accumulate value using adding circuitry, and performing rounding by adding a rounding value to the sum of the shifted value and the accumulated value using the adding circuitry. The same adding circuitry is used to perform both the addition of the shifted value and the accumulated value and the addition of the rounding value in the same processing cycle.
