Method and virtualisation software for producing independent time sources for virtual runtime environments

摘要

The method involves exclusively associating real-time operating systems (RTOS1-RTOS3) with secondary time sources (TSC1-TSC3) that are provided in secondary processor cores (Core1-Core3). A primary time source (RTC) is provided for periodically transmitting interrupt signal (INIT) to a primary processor core (Core0). An overall operating system (GPOS) is operated based on clock signal generated by a virtualization clock module (VRTC), and numerical content of readable memory registers (AZ1-AZ3) are incremented by secondary time sources during existence of interrupt signal.
