Abstract

A method and device for performing switchover operations in a computer system having at least two execution units are provided, in which switchover units are included which are configured in such a way that they switch over between at least two operating modes, a first operating mode corresponding to a compare mode, and a second operating mode corresponding to a performance mode. An interrupt controller is provided and, furthermore, at least three memory areas are provided, and the access to the memory areas is implemented in such a way that one first memory area is assigned to at least one first execution unit, and one second memory area is assigned to the at least one second execution unit, and at least one third memory area is assignable to the at least two execution units.
