Zusammenfassung:Approaches for dispatching routines in an emulated operating system. A method includes executing a first operating system (OS) on an instruction processor of a data processing system. The first OS includes instructions of a first instruction set that are native to the instruction processor. A second OS is emulated on the first OS and includes instructions of a second instruction set that are not native to the instruction processor. A first plurality of tasks is created by the emulated second OS. The first OS individually schedules the first plurality of tasks and dispatches the first plurality of emulated tasks for emulation according to the scheduling.
