Abstract
A checkpoint technique associated with an out of order based architecture of a processing device is described. An instruction may be received by its retirement unit and an identification as to whether the instruction is associated with a speculative error is performed. If the instruction is associated with the speculative error, then a first operation may be performed to replace state values of a first checkpoint of the processing device with state values of a second checkpoint. If the instruction is not associated with the speculative error, then the second checkpoint state may be updated based on the instruction.
