Per index divergence target address cash which remembers the divergence target address of two or more

摘要

Divergence target address cash (BTAC), two divergence target addresses are remembered at least in each cash line. As for BTAC, the index it is attached by the instruction address which is truncated. Whether either one of divergence target address it is taken, as estimate divergence target address the offset which is acquired from the divergence estimate offset table decides. The index it is possible, as for those methods, the hash of the thing and the divergence past record due to divergence past record and the thing, due to gshare value the thing, due to random the thing, those due to round robin order or due to other method to do to attach the offset table with however many methods those due to the portion of branch instruction address to include is possible.
