Local and global monitor for exclusive access

Hi,

My questions are about monitor for exclusive access.

1. If I want to use exclusive access in a dual Cortex cpu system, I need to design local monitor and global monitor by myself, right?

2. If the answer of first question is yes, the local monitor should be outside of CPU, so how the CLREX command works? I mean the CLREX needs to remove tagged address and reset state machine of local monitor. how CPU tells local monitor to do these actions?

Thanks!
