non blocking delayed counter

Hi,

I need to delay a counter without blocking execution... Please, could you give me some suggestion?

Tnx

What board? What OS? What language? What counter? How much delay? If you
want help you need to be specific and show what you have already
attempted. Previous coding attempts are a good start.

BeagleBoard XM, Linux, Narcissus, any counter, any delay.

Thank you
