This is the cache logic with prefetch and micro-prediction enabled.
When only prefetch is enabled, a branch address is marked when the address is detected. The next time the same branch address is encountered, prefetch is disabled. If both micro-predictor and prefetch are enabled, the branch address is still marked as before but the destination address is also saved. In this case, the next time the same branch address is encountered, the branch address' corresponding destination address is fetched by the prefetch mechanism.
