Hi Wychwar,
                        I have put a design for a four digit tachometer that uses one pulse per revolution on the "Yahoo X_Series _Mills forum" in the file section.
It works by measuring the time  of one or more revolutions and calculating the speed from that. At slow very slow speeds it only times one revolution. (So the display is updated at a reasonable rate.) At higher speeds it times a number of revolutions to average out the speed over about a one second period.
I hope this will meet your reqirements.
Les.
