DSP and control theory tooters, how do you smooth a tach signal?

I'm measuring a sequence of tachometer pulses, and I want to turn that into a smoothed current speed number. Everything I know about DSP uses a fixed sampling interval, but these aren't fixed -- the interval is the signal.

This has to be a well known problem with well known solutions...

Thank you.
