System and method for handling exceptions and branch mispredictions in a superscalar microprocessor

摘要: An system and method for retiring instructions in a superscalar microprocessor which executes program comprising set of having predetermined order, the retirement simultaneously groups executed or out order by microprocessor. The comprises done block monitoring status to determine instruction group have been executed, control determining whether each is retirable, temporary buffer storing results register array retirable-instruction results. In addition, further controls determined be transferring their from array, retires directly array. steps buffer, retirable
