Abstract
A data processing apparatus is provided. It includes processing circuitry for speculatively executing a plurality of instructions. Storage circuitry stores a current state of the processing circuitry and a plurality of previous states of the processing circuitry. Execution of the plurality of instructions changes the current state of the processing circuitry. Flush circuitry replaces, in response to a miss-prediction, the current state of the processing circuitry with a replacement one of the plurality of previous states of the processing circuitry.
