I'm new to IBS and I'm trying to use IBS to obtain LLC (last level cache) miss addresses in an online fashion. My question is the following:

What is the highest sampling accuracy of IBS? And is this accuracy of IBS sufficient for obtaining LLC miss addresses online?

By online, I mean that the scheduler's decisions are based on the LLC miss address that is sampled.

Thanks in advance.
