A clock signal arbitration method includes arbitrating between first and
second request signals generated in respective first and second clock
domains that are asynchronously timed relative to each other, to obtain
first arbitration results. These first arbitration results identify a
relative queue priority between the first and second request signals.
Additional steps are performed to transfer the first arbitration results
into a third clock domain that is asynchronously timed relative to the
first and second clock domains. The transfer operation may include
arbitrating the first arbitration results in a third clock domain to
obtain second arbitration results that confirm or correct the first
arbitration results.
