Instruction branch mispredict streaming
摘要:
A method and an architecture for recovery from a branch misprediction in a processor. The method may include the steps of (A) evaluating a branch prediction for a branch instruction, (B) pausing an instruction cache line fetch in response to the branch instruction, and (C) resuming the instruction cache line fetch from where paused in response to evaluating the branch prediction as incorrect to recover from the branch misprediction.
