The Analog Devices ADSP-21020 digital signal processor can be put in
a "saturation" mode in which the arithmetic operations are saturating
rather than overflowing. I suppose this holds for the newer "SHARC"
series too.
Since the 21020 is a 32-bit, floating-point DSP, this could be a nice
platform for saturation arithmetic in demanding real-time systems.
