Abstract: A loop predictor and a method for instruction fetching using a loop predictor. A processor may include a loop predictor in addition to a primary branch predictor. A relatively common scenario in program execution is that a set of branches repeat over and over forming a loop. The loop may be detected based on a repeated pattern of access to a data structure used for branch prediction. Once a loop is detected and it may be determined whether the codes would stay in the loop for at least a duration sufficient to disable the branch prediction. On a determination that the detected loop is locked, a sequence of instruction addresses in one iteration of the detected loop may be captured in a buffer and the branch predictor may be turned off and a sequence of fetch instructions may be played from the buffer.

Abstract: A branch predictor for use in a processor includes a Level 1 branch predictor, a Level 2 branch predictor, a match determining circuit, and an override determining circuit. The Level 1 branch predictor generates a Level 1 branch prediction. The Level 2 branch predictor generates a Level 2 branch prediction. The match determining circuit determines whether the Level 1 and Level 2 branch predictions match. The override determining circuit determines whether to override the Level 1 branch prediction with the Level 2 branch prediction. The Level 1 branch prediction is used when the Level 1 and Level 2 branch predictions match or when the Level 1 and Level 2 branch predictions do not match and the Level 1 branch prediction is not overridden. The Level 2 branch prediction is used when the Level 1 and Level 2 branch predictions do not match and the Level 1 branch prediction is overridden.

Abstract: A method and apparatus for branch prediction is disclosed. A pattern history table (PHT) is accessed based on at least one global history value to obtain a prediction value. The prediction value and the at least one global history value used to obtain the prediction value are placed in a queue. If a branch prediction is requested, the queue is accessed to obtain a prediction value. The queue may include any number of entries and the queue maintains the oldest prediction value at the head of the queue. The prediction value at the head of the queue is used when a branch prediction is needed.
