ABSTRACT:
A mispredicted path side memory is configured to be coupled to a stage in an instruction pipeline. As instructions advance through the pipeline, a result from the stage is stored into the mispredicted path side memory. The result is restored from the mispredicted path side memory into a pipeline stage when a branch is mispredicted.
