sleep in microsecond granularity in linux

Hi there,
Is it possible to sleep in granularity of microseconds ?
From what i know, there is msleep() which can sleep in millisecondsand there is udelay() which busy waits for time in microsecond
granularity.
But I need to sleep ( not busy wait ) for granularity of microseconds ...
Is there a way to code a new API in linux kernel to allow this ? For
example using interrupts ..
Or is there a way to some external hardware timer cards that issue
interrupts after certain usecs ?
Any help / pointers/ tips will be very appreciated.
Thanks,
-Leo
