An embodiment of the invention is a processor for processing loop branch instructions. The processor includes an instruction unit for fetching and decoding instructions including at least one loop branch instruction. A branch prediction unit predicts target instructions to be fetched and decoded by the instruction unit in response to the loop branch instruction. An execution unit executes instructions from the instruction unit and maintains a counter indicating an iteration of a loop. The execution unit includes detection logic for detecting when the counter equals a threshold and notifies the branch prediction unit when the counter equals the threshold.
