ABSTRACT:
A branch prediction algorithm is used to generate a prediction of whether or not a branch will be taken. One or more instructions are fetched such that, for each of the fetched instructions, the prediction initiates a fetch of an instruction at a predicted target of the branch. A test is performed to ascertain whether or not the prediction was generated late relative to the fetched instructions, so that if the branch is later detected as mispredicted, that detection can be correlated to the late prediction. When the prediction is generated late relative to the fetched instructions, a latent prediction is selected by utilizing a fetching initiated by the latent prediction such that a new fetch is not started.
