stm32F3 clock tic reading

I've got a simple control loop and I need to track the elapsed time of each loop.  Duration will be anything from 2u-sec to 500 u-sec.  I'm wondering if there's a system clock tic register or countdown timer I can read each time around the loop to calculate the elapsed time.  I'm sure I could setup a dedicated timer and reset it each time through but thought there might be an easier way reading some SysClock register.   Any thoughts on this?
