A multiply and accumulate (MAC) unit ( ) having a multiplier ( ) and an adder ( ) for providing a calculated result of a MAC operation, an accumulator ( ) for storing the calculated result, and a scaler unit ( ) for selecting a subset of the calculated result stored in the accumulator. The scaler unit receives information defining the subset as a predetermined number of contiguous bits and defining the location of the bits with respect to a radix point. In response to a detected error in the selection of the subset, the scaler unit selects a second subset, where the second subset also has a predetermined number of contiguous bits having a different location with respect to the radix point:
