Method and apparatus for fixing a entering launch state in the case of a computer system having at least two execution units by switching over from register sets

摘要

A method for securing a entering launch state in the case of a computer system having at least two execution units, wherein between a performance mode and a comparison mode to be switched over and for the performance mode is provided a first register set, consisting of at least a first register for a first execution unit and at least a second register for a second execution unit, characterized in that, on switching from the performance mode in the comparison mode a start state for the comparison mode in a second register set is provided, consisting of at least a third register for the first execution unit and at least a fourth register for the second execution unit, wherein the starting condition for the comparison mode is obtained in that, between the first and second register is switched over.
