Fast sort algorthm to sort a very small set.

Hi Folks,

"C"

My microcontroller (PIC) has some nasty deadlines it has to keep, so to aide in that, I'd like to be able to sort four(4) 16bit integers as fast as possible. I don't care how much code it takes as long is it's fast.

Can I have some suggestions as to how you'd do it?

Thanks!
