clipping detection

I'm looking for something fast that will tell me if the data
from a digitizer is being clipped.

Clipped would be N consecutive samples of the identical (or
within one bit) data in a vector array.

Any ideas how to do this quickly?

I though about taking the derivative and then checking for
zeros but I'm getting messed up on quickly getting the N
consecutive samples sorted out. In other words, at 100 Hz,
then I would say that 5 identical samples suggests clipping,
but this can happen at any position in the output array.
