Consider the 4?bit saturating counter as a branch predictor with 16 states from 1111 to 0000? Describe in words the circumstances where such a counter might be effective.
What will be an ideal response?
If the branch predictor works in the same way as a 2?bit saturating counter, it has 16 states; 8 of which predict
take and 8 don’t take the branch. If you are in a run of taken or not taken branches (more than 15) then you are in
the strongest taken (or not taken state). It will take a run of eight wrongly predicted branches in sequence to
reverse the decision. Therefore, you might use such a system in circumstances where very longs runs of a branch
are in one direction, and you do not wish to reverse the direction unless there is a change of direction spanning 8
branches.
