Abstract:
A method for implementing a real time control program in a non-real time operating system on a processor of a PC system,wherein at least two interrupts are initiated for each operating cycle of the PC system by means of at least two interrupt calls of an internal interrupt source of the PC system,one of said interrupt calls triggering the change of environment from the non-real time operating system to the real time control program and another of said interrupt calls triggering the change of environment from the real time control program to the non-real time operating system,whereby run times are allocated to both the real time control program and the non-real time operating system in each operating cycle, thereby enabling a deterministic time sharing between the real time control program and the non-real time operating system, andwherein the non-real time operating system is provided with substantially minimum run time.
