Abstract
The present disclosure relates to a method of processing an interrupt comprising a peripheral unit sending an interrupt, the interrupt being intended for a virtual unit executed by a processing unit, transmitting the interrupt to an interrupt control unit coupled to a processing unit, and the interrupt control unit storing the interrupt in an interrupt register. According to an embodiment of the present disclosure, the interrupt is transmitted to the interrupt control unit in association with an identifier of the virtual unit receiving the interrupt, the interrupt register in which the interrupt belonging to a set of registers is stored comprising one interrupt register per virtual unit likely to be executed by the processing unit, the interrupt being transmitted to the processing unit if the virtual unit receiving the interrupt is being executed by the processing unit.
