Instruction set test
Crazy idea (more like insane). Do the MCUs in question have OCD? If so, perhaps the OCD unit could aid in performing these tests?

finding average of signal
I prefer the form: new = (1-x)*(input - previous) + previous Which trades a multiply for an add. Not a big deal with integers but can speed things up noticibly for floats.
