Taking microsecond timer without interrupt

Hello

I'm looking for a solution to get the time between to input signals in microsecond resolution.

But I do not want to use an interrupt counting up all microseconds.

Is there a convenient solution / method?

Busy-polling the signal pin, and on change, fetching the counter values from a properly configured timer.

This solution will eat up all available MCU cycles while running (which is usually unacceptable on real-life systems).
