AbstractAn apparatus for automatically detecting overflow and imminent overflow conditions as data is transferred from an accumulator to a postscaler. As the data is output from the accumulator, the appropriateness of the predetermined scale factor to be used by the postscaler is determined. If an overflow condition will occur at the output of the postscaler, an overflow signal is generated, and the output of the postscaler is forced to b1;1. If the output of the postscaler will produce data with an absolute value of greater than 1/2, an imminent overflow signal is generated.
