摘要： A process for the execution of a first application program of a first control unitto a computer, functions to control actuators and / or sensors and / or functions for

processing and / or provide information from actuators and / or sensors are executed bythe first application program, wherein comprises first control unit, a control devicehardware with at least one first processor core of a first processor core type, thecomputer has a computer equipment (1) comprises at least a second processor core of asecond processor core type, wherein the first processor core-type and the secondcalculation engine -type at least differentiate present a source code of a control deviceoperating system, wherein a first interface between the control unit hardware and thefirst application program of the control unit is formed by the control device operatingsystem, a source code of the first application program v with respect to the usedcommand set the source code of the control device operating system and the sourcecode of the first application program to be compiled for feasibility on the secondprocessor core type, being produced by compiling a first virtual control unit operatingsystem (6) and a first virtual application program (8), wherein orliegt, the computerhaving a simulation environment (7), provided a simulation environment interface (9) fordelivering a date and / or an event to the first virtual application program (8) and / or thevirtual control device operating system (6) available by the simulation environment is, anda computer operating system (5), wherein a second interface between the computerequipment (1) and the simulation environment (7) is formed by the computer operatingsystem and a hypervisor (2), wherein the hypervisor a first virtual machine (4) of thecomputer provides, and by the first virtual machine (4) Comput he hardware (1) partiallyor completely provided in the form of virtual hardware available, and the virtual hardwareincludes at least a first virtual processor core, said virtual control device operatingsystem (6) is carried out in the first virtual machine (4), initiating the simulation

environment (7) execution of the first virtual application program (8) within the controldevice operating system (6) within the first virtual machine (4) via the simulation

environment interface (9) and controls, wherein controlling the transfer of data and / orincludes events to the virtual application program (8) and / or the virtual control deviceoperating system (6), and the first virtual application program (8) through the virtual

control device operating system (6), a direct access to the virtual made available to thehardware of the first virtual machine is provided (4).
