ABSTRACT:
A system and method for overflow and saturation processing during accumulator operations that reduces the error in a saturation operation. Upon overflow, additional guard bits used in conjunction with an accumulator allow a user to continue processing without any error in the values used in computations following the overflow. A saturation condition can be detected following the overflow the appropriate maximum value stored in the accumulator upon detecting saturation.
