An agree predictor is a two-level adaptive predictor with globally shared history buffer and pattern history table, and an additional local saturating counter. The outputs of the local and the global predictors are XORed with each other to give the final prediction.
From Branch Predictor article Two-level adaptive predictor "Assume, for example, that a conditional jump is taken every third time. The branch sequence is 001001001... In this case, entry number 00 in the pattern history table will go to state "strongly taken", indicating that after two zeroes comes a one.
The branch predictor in a core tries to predict the outcome when there are diverging code paths or branch. Lion Cove's L0 Branch Target Buffer (BTB) cache has been doubled to 256 entries to store a higher number of target addresses for a taken branch which can be used to help predict the next branch and reduce the number of misses.

This approach is employed in a variety of areas, including branch prediction in pipelined processors, value prediction for exploiting value locality, prefetching memory and files, and optimistic concurrency control in database systems. [1] [2] [3] Speculative multithreading is a special case of speculative execution.
