Patent US 10,083,041

A method for outputting alternative instruction sequences. The method includes tracking repetitive hits to determine a set of frequently hit instruction sequences for a microprocessor. A frequently miss-predicted branch instruction is identified, wherein the predicted outcome of the branch instruction is frequently wrong. An alternative instruction sequence for the branch instruction target is stored into a buffer. On a subsequent hit to the branch instruction where the predicted outcome of the branch instruction was wrong, the alternative instruction sequence is output from the buffer.
