Abstract
The invention pertains to a method and apparatus for implementing a real time control program in a non-real time operating system running on a processor of a PC system, wherein a change of environment from the non-real time operating system to the real time control program and a change of environment from the real time control program to the non-real time operating system are carried out by means of interrupt calls of an internal interrupt source of the PC system in an operating cycle so that run times are allocated to both the real time control program and the non-real time operating system in an operating cycle.
