2.12.3 RN SAM address hash function

For the RN SAM, the HN-F partitions are treated as a single destination. To determine the HN-F partition responsible for a particular address, the following hash function is applied:

------------------ 6XP/2HNF ------------------
HN-F identifier: Which HN[1:0] = ^ addr[43:6];
                                
-------------------------------- 8XP/4HNF ------------------------------
HN-F identifier: Which HN[1:0] = addr[43:42] ^ … ^ addr[9:8] ^ addr[7:6];
 

This hash identifies which HN-F is responsible for an address, but the identifier must be passed through the RN SAM to obtain the node ID of the identified HN-F.
