Meta predictor restoration upon detecting misprediction

A method comprising:

• detecting a branch misprediction within an instruction pipeline;
• storing a set of misprediction history values within a hardware register;
• and
• restoring the hardware register based on the detecting of the branch misprediction.

A method, comprising:

• receiving an index value correlating to a pipeline branch prediction and a misprediction history value at a hardware-based meta predictor;
• generating a misprediction value by the hardware-based meta predictor, the misprediction value comprising a value indicating whether the pipeline branch prediction was correct or incorrect;
• and
• generating a final prediction based on the pipeline branch prediction and the misprediction value, the final prediction comprising information indicating whether the pipeline branch prediction is to be taken or reversed for the pipeline branch request according to the misprediction value.
