Abstract
A computer system includes a first predictor circuit configured to generate a first predictor signal, and a second predictor circuit configured to generate a second predictor signal different from the first predictor signal. The computer system further includes a TIP arbiter configured to receive the first predictor signal and the second predictor signal, and to select one of the first predictor signal or the second predictor signal as a final prediction of a target address for a fetched branch instruction. The selection is based at least in part on a comparison between a branch address of the fetched branch instruction and a stored tag value, along with a counter value stored in the arbiter entry.
